Okay so you know that trend where the main cast goes into one character's mind for a bit and finds multiple versions of them? And how canon usually plays this as some sort of ~unknowable metaphor~ but systems and allies usually identify it as evidence for plurality?
Okay yeah so take that but instead of the second half, make it so the character whose head is getting investigated is like. Wait. Why are there multiple of me. And this is how they find out they're plural.
(surprisingly, it was not the earlier TADC ask that made me think of this, although I see the connection, lol)
