Maestro called out that there is "something wrong" with Ruby. She is a paradox. Somehow, she is her own Mother.
maestro even said something about the "Oldest" one, seemingly different than the one who waits?
@@jordanmcculloch1169 i think its also sutekh, the "oldest one"
@@Philmaster07 yeah It very well could be, she just seemed surprised he was there while then also mentioning the one who waits mere minutes later as if they were different entities
If she Knew the one who waits was coming, why was she surprised he was there
If she is,then does the Ruby we’re seeing have a belly button 🧐💭(think about it)
@@Philmaster07 are you saying Ruby has been intimate with a dog 🐕 😂
I think the Trickstar is her parent because Ruby's song in The Devil's Chord is literally the Trickster's theme in SJA. BUT, I also think that the person who dropped Ruby off isn't even her parent, and that's how they will make it the Trickster but not reveal it this season.
I have a theory: she wasn't pointing at the doctor, she was pointing at the tardis. Maybe she was trying to WARN the doctor because she could see sutekh wrapped around it?
Is that even a theory, i thought that was obvious from the episode. It annoyed me the doctor didnt cotton on to it
Yes!
What if Mrs Flood didn't make Cherry a cup of tea because she simply didn't know how to make one?
Yeah Mrs flood probably had a valid reason, she was too busy destroying or trying to save the world
Maybe Mrs Flood knows Cherry is a Harbinger that’s been waiting on a bed this whole time and that’s why she didn’t make her tea 🤔 jk!

If Susan is Ruby's mother, that makes Ruby the Doctor's Great-Granddaughter, not his Daughter, surely?
Freudian slip?
The Doctor told Kate Stewart that because he's a time traveler he could have raised his granddaughter before having his daughter.
Basically saying as much is the case... meaning that the doctor hasn't had a daughter yet... Meaning that it's possible that Ruby is his daughter. And that Ruby will someday have Susan. Sort of like Amelia pond has River song. It's out of the doctor's timeline sequence of events
@@EskoBomb What the Doctor said I am well aware of, but this conjecture has nothing to do with Susan's parents, just that the lineage is as follows...
Doctor > ????? > Susan > Ruby
Thus great-granddaughter.
@@giociampa well I missed the conjecture altogether I guess. Good day sir
@@EskoBomb No problem.
has anyone thought of Jenny (doctors' daughter) Jenny has been traveling by herself.
I came up with the Ruby is her mum theory during 73 Yards, because I thought the old woman was Ruby from the beginning
What if whoever Is dropping Ruby off isn't Ruby's mam. It could be something where maybe something dramatic happens and her mother is killed or dies straight after her birth. Like maybe they come across a pregnant woman about to drop, when the baby is born the mother dies and says "Ruby road" that feels quite RTD level of heartache
I think ruby is a living version of the puzzle box from SA I think her mother is a trick I don't think she has a mother I think that the trickster created her
I think the same, however that would make the trickster her father.
"Next of kin" was in a loop in Boom when Ruby was shot, so... Ruby could be her own creator.This and the loop in 73 yards, both point in the same direction.😀
Low key truths
I think her Mom is the Bad Wolf, Rose when she was merged with the Heart of the Tardis. We know the Tardis is beyond the constraints of linear time and would know that she would be consumed by Sutekh at a later date so she places Ruby in the right place and time to be a a new heart
I always thought the Bad Wolf was it's own entity. A consciousness formed by Rose and the TARDIS, now drifting through the Time Vortex for eternity
I’ve been wondering how the tardis reproduces as she is a living thing. We kinda see her do so with bad wolf (almost a child of the tardis) and river (who is called a child of the tardis). I’ve wondered is ruby is the child of the tardis as well.
Sunday is the original day of creation! She is a self willed life, the key is Sutekh’s Ruby stone
The boots may be a clue that it’s the 13th Doctor, because it alludes to the Bootstrap Paradox (as explained by the 14th Doctor when he explains how he became Beethoven to get the music out to the world).
Yo... That's good logic
10 and roses daughter from parallel world
I like that. No one would see it coming and it’s something RTD would do. Shamelessly and gleefully
Thinking about it: Maestro said there is hidden song but we heard the Trickster's theme before the hidden song... Could be the Trickster!
Personally, I would go for Susan being related to Ruby considering the family arc and there's been too much focus around Susan this season. Plus, "the twist at the end": the doctor implied that he has a grand daughter before a daughter, my crazy thought is that Ruby could be Susan's mum. Having a knowledge of the future event Ruby was dropped at that church, and the hooded figure tried to warn the doctor about Sutekh by pointing at him. This implies to me that if it was the Trickster he would not try to warn the doctor about Sutekh. So I would rule it out but not completely.
There's another personal thought I have concerning the pictures of old Ruby, (and even as seen in Unleashed episode) shows that she has a scar on her face, but during 73 yards we never were so close to see that.... why botter to do this?! We could see more of old Ruby, also strangely in Legend of Ruby, Kate and Unit people speaks in meters, why?! In UK you would normally not use meters to give a distance but yards... 66 meters is 73 yards, the hooded figure could be old Ruby 73 yards away from the Tardis and the doctor. Some sort timey-wimey event happened and the doctor went back a second time on Ruby Road when he disappeared during 73 yards...Could explain why the hooded figure stay away and does not reveal her face.
Two things can both be true at once. I think Susan is one parent, and the other is The Trickster who tricked Susan potentially.
But I think Ruby is the Harbinger for Hecuba. Being the Queen of time, you most likely have the skill level to trap Sutekh again. And Susan is Mrs Flood in disguise. Maybe even with a perception filter or something.
I don't know, they are just thoughts. We'll find out this week.
The use of Metres by UNIT is quite correct, and probably not a plot piece. The international metric system (SI) is the official, legal system for most purposes in the UK, including the armed forces. 68.58m is 75 yards. 66m would be 72.18 yards.
Really, I never heard people giving me a distance in meters. During covid I have never social distancing given in meters including in government's buildings or public spaces!!!
For short distances and journey measurement it's imperial not metric, I believe. I also believe that military use both in UK.
My believe is that Imperial units are officially used to specify journey distances, vehicle speeds and the sizes of returnable containers (milk, etc..)
People born before decimalisation tend to use imperial measurements for distance. I started primary school on the year decimalisation came into force.
So I can use inches or centimetres but favour centimetres. For larger distances I was taught metres rather than yards. When learning to drive we use miles an hour and not kilometres per hour. So it depends.
My comment to 73 yards. This episode is in yards.
Unit is talking and measuring the distance of old Ruby in yards.
Kate the same character is giving the distance in yards.
The software that Ruby uses given by unite mesures distance in yards.
The same character Kate did not use metrics at all.
73 yards is 66.57 meters exactly.
All of a sudden Kate speaks in meters... so yes I definitely think that this is strange. This is a two parter episode, RTD could have use meters instead to build up the mystery.
Again old Ruby as a scar on her face, the fact that 73 yards was distance calculated by RTD on purpose, a distance you cannot the face good enough means something... you have lady you do not want her face to be seen closely and you decide to add a scar on her face? Why? Why would old Ruby have a scar on her face?
If it's the Doctor dropping off Ruby Sunday, then possibly him crossing his own time stream may have released Sutekh. Explains why there's another Tardis for Sutekh to latch on to.
Since there is 'always a twist at the end', what if the person delivering Ruby is just a Kind Woman, not her mother at all?
It seems odd to assume that the person who dropped her at the church *must* be her mother
Oooh, that makes sense
OMG thank you i thought i was thé only one not inderstanding this ...
I dont get why the characters assume it MUST bé her mother dropping her off when it could literally bé anybody... Liké i dont know maybe that woman found her abandonned Somewhere else and brought her here or maybe she was abducted or whatever ... This feels like a Big storytelling flaw to me that no one IS thinking of those options
This one might be a bit out there, but we know that the doctor has had a child admittingly via a clone making facility in "The Doctor's Daughter" obviously he still thinks they died but we never did find out about what happened to Jenny, perhaps, Ruby is Jenny after a regeneration and has somehow managed to wipe their own memory due to a chameleon arch?
I kind of like that theory
I called this out as well. She's wearing a tank which reminded me of the military garb they were all wearing. Then I realized that they weren't wearing tank tops in that military
Isn't in this episode ending reviled that Jenny lives?
I have a little theory about Susan Triad Technologies. The Dr said that he had the wrong anagram but this had me thinking. I think her last name , Triad, is still relevant. The is the Triad of Memphis : Ptah, Sekhmet* and Nefertem.
Sekhmet is sometimes called the Eye of Ra and is known to be strong, mighty, violent. She also is clothed in red, Ruby.
Very surprised that 2 of my very unique theories made this list. Maybe Adipose saw and liked them.
Or maybe my they weren't as unique as I thought
Surely susan being ruby’s mum would make her the doctor’s great granddaughter? 😂
Despite my previous comments. I just realised. It's not her mother, it's her father. And it's clearly Palpatine.
The 13th Doctor being Ruby’s mother would possibly cause the internet to implode. Seriously. It would need to be quarantined from all the Chibnal era hate that would be boiling in the Wi Fi signals in the air
Backing the ruby is her own mother theory (at least for me, so far) is the parralels with the doctor as orphan/refugee presented in this new run.
My hope is that'll also introduce the possibility as cannon that the timeless child might be an oroborous loop in itself as a consquence of cheating death on trenzalore.
I wouldn't put it past RTD to pull a swifty and make Ruby Mrs Flood's mother rather than her daughter. In that way Mrs Flood has already done the travel through time bit and ended up in the past in order to see her own mother grow up.
Ruby's mum still looks like the 13th Doctor to me...
She is The Master.
Ruby creating herself is a Bootstrap Paradox
Who really wrote Beethoven's fifth?
who is her mother?
actually in terms of what we know on screen people are focusing a lot on a different question - who is the person who leaves ruby at the church?
that person is, based on what we can see in 'ruby road', female, not old, white, slim to average build, not short or notably tall, appears to have slim lips and a slim nose, and visible knuckles (ie not chubby fingers). that's not a ton to go on. the only prominent character we know of in the story that could, 20 years ago, fit that description is susan triad. susan is not a 'bad person' just one that, like in pyramids of mars, gets posessed and used to do evil for sutekh. but that would suggest she's likely dead now. :-/ oops. except maybe not because she maybe is the tardis in human form. her 'posession' in human form parallels the tardis being 'posessed' by sutekh in jackal form.
way more interesting, and thisjust might tie in to the triad thing... in pyramids of mars the eye of horus glows red. like... ruby red. or is it rose red... or maybe cherry red? not sure. Its one of that triad of reds anyway.
the eye kept sutekh trapped. the eye got destroyed. so now the fragments, if they can be reconnected and healed (as I remember you'll need the milk of a gazelle for that!) they can re-trap sutekh.
but the bits are on mars and likely you'll need a timelord to collect them and seed them into the doctor's timeline - ruby, rose and cherry.
why the hell, after all, do we need rose in the story? why is mrs flood focused in on cherry? and while we can say rose has a reason to be there, she's focused on finding her mother, not on the sutekh problem. all three seem peripheral to the sutekh story. which is why they are essential
you heard it here first
4:21 if Susan is Ruby's mother Ruby would be the Doctors great Granddaughter not Daughter
Doctor told Kate he has children out of sequence. Granddaughter first... No daughter yet...
That would make Ruby Susan's mother if she's the doctor's daughter and I think that's what they're hinting at.
Love your content and well done for working out who Ruby's mum was
It's Either """ROSE TYLER """ or """RIVER SONG""" Ruby's Mother !!; 🤗🤗🤗
Mrs Flood has a motherly vibe, a judgemental mother saying Ruby is too short
OK, crazy thought. Is Mrs. Flood Jenny? (I just re-watched The Doctor's Daughter and thought "Wait -- he's got another daughter out there...") Jenny had "regeneration energy" but didn't regenerate, so there's every reason to believe she would age and eventually die. Jenny was gorgeous, and Mrs. Flood is gorgeous for a woman in her 70s or 80s. Jenny was shorter that Mrs. Flood, but she was newborn and might have had a growth spurt like she suggested to Ruby. While I think it's more likely Mrs. Flood is an old Ruby or someone else entirely, I'm pretty sure Jenny will pop up again sometime.
I don’t think she’s the Doctors Daughter, 10 said to Donna that he’d been a father before. He also dodges when Amy asks him if he’s had kids in a Good Man Goes to War, which Russell did say to view prior to the finale.
Calling it, Ruby’s mum is River Song, making Ruby The Doctors daughter.
The Trickster could work, so ce the idea of him leaving a baby on a doorstep was an old idea meant for the next season
The kind woman?
May be a reference to "Compassion", the Doctor's assistant from the books who became a living humanoid TARDIS.
Maybe Ruby is a phoenix and instead of regenerating like time lords she becomes a baby again.
The Thirteenth Doctor being rubbies mom? I've never heard that theory.
i have 🙃
I have heard and even heard a joke about it. 🤣
I find it very odd and bizarre that the doctor says he doesn’t have kids yet unless Ncuti is an alt u doctor. Ten spoke of having had kids in the past (not grandkids) so it makes no sense that he doesn’t have them yet. Ten knew his kids (and so did two). As far as the woman being ruby I agree. It’s all a distraction to defeat sutekh. Ruby is a trap but not for the doctor. She’s a trap for sutekh. She could be a baby farm baby.
Perhaps the woman who brings Ruby to the church is not her mother at all, but someone who did it in order to set the story into motion, perhaps because they already knew that it had happened. Having said that I don’t think it's Ruby herself, the woman seems taller, but she seems to be hiding herself, perhaps knowing that she's being filmed (timey-wimey et all). There's another interesting bit about Ruby - following the Susan Twist thing being a Susan red herring, complete with the actress having her name, what did Maestro say about a song buried inside Ruby? A carol? As in Carole (Ann Ford)? Has RTD been playing the names and anagrams game with that too?
There has been rumours for over a year now that 13 will be appearing in RTD series. RTD said he would have loved to work with Jodie, so I think Jodie's doctor will return at some point
About Trickster theory, there is some more evidence, in Devil's Chord Ruby sings notes that are used in the first episode with the trickster, +complicated stuff with Ruby possibly being part of Sutekhth plan to trap the doctor and his history of teaming up with other gods (in comics I think) it would make sense to call a god of traps to join in. BUT unlike Trickster hooded person has her hands and visible legs, which don't really correlate with the Trickster as we know him
What about the Doctor's daughter Jenny, we know that she can travel in time and space?
I bet the comment on "what is the memory of a tardis?" in the time window was a foreshadowing of Ruby going in it while being stuck in the time window room and it being linked to the memory tardis that we've been seeing all the past drs and companions. Would be awesome.
Why does everyone assume the woman dropping off ruby is her mother. She could just be the equivalent of a delivery driver, dropping off an important package lol
She's delivered by the Kerblam man?
What about Ruby being the Drs child of a previous incarnation from before they were mind-wiped?
Now that's what I call a good video
So my theory with the whole reveal that the doctor doesnt have a child yet cause timelord stuff, is what if thats River? It HAS to be someone we know. They keep her face hidden too much to be a new character. It could be during her time with Capaldi's doc at the singing towers she became pregnant. Then before going to the library, she leaves her child at the church. The reason she doesn't tell the doctor is because she knows he doesn't want to bring people into his life in a dangerous way. Idk. Silly theory. But would be cool.
Whoever Ruby's mum is - I think RTD will want to nail down the idea that Carla was the mum who stepped up and raised her so I think the answer she finds will be dissatisfying
She may be the daughter of the Moment. Remember the big red button shaped like a jewel. Was that a ruby?
If Susan was her mother then Ruby couldnt be the doctors daughter
I was confused about this too... that would make Ruby the Doctors great granddaughter
Well. She COULD, but it is usually frowned upon.....
I heard the disciples of light line when rewatching recently definitely thought that sounds like it could be ruby!
The only way that the 13th doctor as the mother of Ruby would work for me is if another of the Doctor's regeneration was the Father
Bro, even Master/Missy isn't enough insane to do this.
Surely the figure with the hood is the actress Jodie Whitaker. Wasn't she revealed as the 13th Doctor by pulling back a hood in the promo? And the lace-up boots.
A villain picking a companion wouldn’t be new; Missy is the one that gave Clara the Doctors phone number and Clara had already jumped into the timestream since we had already seen her twice.
I've noticed you didn't include Claudia Winkelman on the list 😂
Back when David tenant was the doctor he had a daughter played by his actual wife ruby could be connected to her no one seems to talking about this
Ruby is human as scanned by the doctor whilst she leaves the Tardis at the end of Space Babies at 46:24 - this might cancel out a lot of the theories. The genetic code given is JD6784 which corresponds to a homo sapien (human) species with an age of 19, and the scanner also tells us that.
I love that you made a reference to The Acolyte. I wonder if you are following and maybe even a fan? Would you ever divert your Doctor Who content to review and share your thoughts on the Star Wars show?
I was not expecting the Osha swipe 😅
Heres a crazy theory for you. In the Christmas special Donna survived because of a "shared inheritance" with her daughter Rose. What if a smilar thing is true for Ruby.
What if Bad Wolf is actually an Elder god in the same way that Sutekh is, and when Rose Tyler looked into the heart of the Tardis she became the avatar of Bad Wolf. Later she and the meta crisis doctor have a child and she is dropped of at the church on Ruby Road by Rose.
After Eccleston absorbs the energy from Rose all she can remember is singing in her head. Remember Maestro said Ruby had a hidden song in her heart, could this be the bad wolf song remembered by Rose Tyler?
Bad Wolf had the ability to reshape reality, and this could explain the snow, Ruby is subconsciously using her shared inhrritance to recreate her earliest memory, the snow falling the night she was left at the church.
Seems like a very RTD thing to do.
What if it's Susan and Ruby ends up being the Doctor's Great Granddaughter?
Has anyone seen the way Ruby is holding her lapels in the photo in last week's Radio Times. Very First Doctor! Peter Capaldi did it when he was revealed as the Twelfth Doctor, too.
The Doctor said “he didn’t have kids yet” could mean he’s talking about his personal timeline as in he just didn’t conceive he’s kids yet, but could know them as a different name or wasn’t galifrey supposed to be in far future so in the sense of world timeline he hasn’t had kids yet as in that it’s not the physical year he had kids.
Queen of the time
Ruby’s mother is Sian Clifford, the Kind Woman. She points at the doctor because it’s his fault that she had to give up her child. Dropping her off at the church on Ruby Road was necessary for some reason, because something something being exposed to Sutekh on that night will give Ruby the power she needs to defeat him.
Ruby Sunday is the daughter of River Song. Same initials.
The way chibnall wrote the 13th doctor, I doubt she will be rushing back 😂
Susan Triad is everywhere but Ruby Road, I think it must be her
Given that we have only 8 episodes and a huge budget,I think the answer depends on which of the final episode versions they've probably shot.
Ruby's mother could be connected with Osiris, the Osirians, Rah (Sun Day, and gods can make sure their offspring wind up with the right family name.)
"Evil! Evil since the dawn of time!" Sounds like "the oldest one" to me, so there could still be a Fenric connection (some incidental music red herrings on previous episodes suggested that possibility, subconsciously)
Is Ruby's mother The Doctor? It's possible twice over, given both bigeneration and the line of dialogue about the Doctor yet to be a father (despite already claiming to be one. Now that's a paradox!) The 14th Doctor could easily regenerate onto the Curator, and another Jodie Whittaker incarnation and hell even Merlin and ultimately the Valeyard. Moving on...
Now introduce yourself to Rakija (fruit brandy) and take some headache pills, you'll need them to believe this idea.
Ruby is the Doctor, which is why her mother points. Her mother is telling the Doctor that Ruby is himself. Ruby becomes the Timeless Child and somehow gets her abilities to chest death (Sutekh) by regeneration. Who in this context is Ruby's mother? Rah, the Sun God.
Ruby is Susan, the doctor's granddaughter, her mother is Jenny, the doctor's daughter, she doesn't even realise she is a timelord because she is on her first incarnation. She changes her name to Susan so that the doctor recognise her name from his past. It's all timey-whimey.
Britush people must do it differently.
If Susan is Ruby's mom, Ruby woukd not be The Doctor's daughter.....
This ain't PornHub......
Just finished watching the finale, man i got emotional
Ruby being her mother can't be possible. She doesn't remember her parents, if she was her own mother, she'd remember.
An Osirin that makes sense is the mother is Isis. In mythology, she gives birth to Horus the enemy of Sutekh. Isis also hid herself from Set during her pregnancy with Horus. So my guess Isis gave birth to Horus' sister who will pick up her brother's reins and defeat Sutekh.
I am convinced Ruby is the daughter of Isis.
its probs gonna be ruby carying herself as ruby found her younger self and is delivering herself to the church
You forgot to mention River Song man..😂. someone was rattlin on the other day aboot some book that was written awhile back called The Ruby's Curse....I divvent knaa what the crack is about that only someone said it were her like 😊
Leela is Ruby's grandmother. Leela had a daughter who gave birth to Ruby but she was killed in the Time War. Leela escapes with infant Ruby to Earth knowing the Doctor will find Ruby.
Wasn’t the eye of Horus In the river song novel and it was a large Ruby what if she’s a weapon made to stop Sutekh
Everyone keeps asking who is "She" but are we even sure it is even a woman. It could be a man or even a demon/villian
I feel like trickster he is being mentioned through out the episodes
@@marinadelrey339 we see part of their face it isn't him
@@Foxtrot5 In disguise…
Looking back at Space Babies being the first episode is starting to make sense to me. It seemed like a nonsense episode but I think it ties into who/ what Ruby is.
Carla = Clara
I'll be honest. I was dubious of Sutekh when you first mentioned it. But with Ruby I am certain I have a grasp on this. I think the Woman under the robe, is Not Ruby's mother. It's Mrs Flood. And that some future story will see a younger Mrs Flood being given the baby by either The Doctor, or some other clearly alien. ie; next season she has to look for her mum in space
Is there any reason she can’t be Rivers daughter?
The master connection
Imagine what fun RTD has watching your videos….and I’m CERTAIN he watches
My Theory: like with the weeping angels, that which holds the memory of a Tardis is a Tardis, it will become the Memory Tardis
The theory I think is most likely is that Ruby’s mother is the 13th Doctor, The reason I say that is that after The Giggle aired Russell said during the commentary for it ‘every Doctor bi-generated as well in their own personal timeline at the same location they originally regenerated’ so my theory is that if that’s true maybe 13 awoke on that cliff edge and sometime later somehow conceived Ruby? Plus the Doc Martens boots are very similar to 13’s ones so I think dismissing this theory immediately ain’t exactly fair
Ruby is half human, half time lord, on her mother's side. Susan is Ruby's mother and the season will end with Ruby saying, "See you around, Grandad."
One theory: River Song? Same initials...
S teir is surely river song because then it would make sence that ruby is the doctors daughter
I’d like it to be The Trickster, but I just do not think they have the time to include them within the confines of the story with Sutekh. If they were going to tweak it they could have Ruby’s mother give up Ruby in return for living as a deal with The Trickster (that being Mrs Flood cos why not) but I fear this would undermine Rubys found family with Carla and Cherry.
I bet it's the trickster is the cloaked figure, the music from The Devil Cord was the same one that they used in the Sarah Jane adventures when Sarah gave the memory cube to Maria, which helped her remember Sarah when she was basically erased from everyone memory after the incident on that pier when they were kids. I think I saw somewhere that Russell wants to reuse the Sky storyline again. so I betting it has to be him. Even before the legend of Ruby Sunday, I was guessing the one who waits was either Suetkeh or the Trickster.
However, if it is not the trickster then I guess Ruby's mother is a new character (maybe the kind person from the cast list) and is also the one who saves the day. The synopsis did say that one woman will save the day (unless there's another twist and it's actually Susan Triad who saves the day). Although at the same time, anything is possible and is anyone game at this point, lol XD.
It could be ruby herself,or the trickster or maybe a random person or could be rose and 10ths doctors daughter from the parallel world or she could be Rivers daughter
I would be sad if they don't put the song Ruby by the Kaiser Chiefs for Ruby
Mrs. Flood's name might be a Biblical allusion referring to the flood in the Book of Genesis that wipes the slate clean and life on Earth can start anew. My theory is that Mrs Flood and Ruby are the reset switch that reboots the Universe after Sutekh destroys everything.
As the last episode is still in the future for me I'm going to share some theories I ran out of time for sharing before I find out if I'm right or wrong by watching it.
Firstly, as you are clearly aware but don't explicitly say here the figure does not have to be Ruby's mum, it's just someone or something, Ruby is just assuming it is her mum because she wants it to be. I think.
Secondly you maybe missed that who/what it is COULD BE CHANGING with the time/memory flips, The Doctor, my memory of this keeps changing, time keeps changing, and of course time is always in flux for the Doctor and company because of The Doctor and others meddling with it. I think it is different things with different flips of various time switches, things that do or do not happen and maybe characters/ entities that do or do not exist or that live or die in these different possibilities. Would explain the fuzziness, lack of visibility, perhaps also true of '73 Yards'' mystery figure. perhaps alluded to by the snow and the snow of the videotape.
So the true answer might actually be 'some of the above', at one point would it not also be the current doctor as he saves baby Ruby from the goblins and returns her? So Ruby could have been placed there at the same time several times but in different 'changed' timelines (another timeless child in this respect) where each placement is sequential yet not sequential in a very time travel kinda way, yup, the bootstrap paradox again, a moment happening before and after and before and after etc itself. that out of sync clock does after all show 308, 8 for infinity and loops?
I think ONE of these variations in who it is is the trickster as the character points which is the Tricksters changing/ unexisting things etc signature move. I won't TLDR this even more with all the links but there are loads across all series of The Sarah Jane Adventures, check the trickster's doings in that, they are interested in Sarah Jane's memories to eliminate The Doctor and SJS is in The Pyramids of Mars thus also linked to Sutekh encounters. Everything about the Trickster totally fits them actually being in this storyline. They get one of Sarah Jane's childhood friends to swap deaths with her, they use her unknown parents as a lure to trap and trick her, Trickster can use changes in history and weak unstable points in timelines to manifest physically through changing something, Maria ceases to exist due to trickster, Sky was a trickster trap and (was to be revealed as) its daughter. Left as a baby for SJS to find. Links thematically to twinning and possible duality per how this may tie in to Sutekh maybe having twin aspects. Goodbye Sarah Jane Smith had a 'replacement' for SJS enemy Ruby White (but those Ruby White links more thematic than tied in I feel unless it was to also be revealed the trickster aided this character).
The trickster tells SJS I am nothing which echoes Sutekh's arrival speech (Sutekh also says 'I am the loss' as Ruby Sunday looks at the mystery and-or mother figure, the UNIT victim said 'I am lost' and this would fit the trickster taking people out of timelines and the loss caused by death.) Also fits things like the not things having no physical form trying to manifest as with Sutekh and others, plus death as death leaves just dust and memory, perhaps soul or spirit, but no physical form.
