Blaine might also be a Psychic Gym because Scientist=Smart=Psychic, but the Mewtwo thing is probably also a reason, especially since in the Manga Blaine did work on the project(there is a theory MR Fuji did too, but that's not important) and used his own DNA to fill in at least some of the blanks of Mew's DNA. Edit: Turns out we both got the ditto Quest wrong, at least you completed it in the end
