Mass Effect 3 - Kelly's death - All variations

If you had dinner with Kelly Chambers in ME2, you can meet her at the refugee camp on the Citadel in ME3.
When you first meet her, if you don't advise her to change her identity, Cerberus agents will find and kill her during the Citadel Coup.
Later, when you meet her again, she will reveal that as a yeoman she had been sending reports about Shepard directly to the Illusive Man. If Shepard does not forgive her for doing this, Kelly will take her own life.
After the Citadel coup, you can overhear a conversation at the refugee camp about Kelly's unfortunate fate.
Back on the Normandy, Ken will deliver the sad news to Gabby.
