(fallen london stamps by it's interesting encountering characters we super vibe with post-system-stabilization. like... a really common experience that gets reported in the plural community is brains making new headmates based off of fictional characters REALLY easily, to the point that some systems get nervous about engaging with media at all
and the thing is, we kind of can feel where that comes from, because we used to fragment easily. and we can still feel the process of that starting these days, but then it's... interrupted? and whatever traits that called to us from the character in question get integrated into us existing individuals instead, instead of aggregating into a new one.
I guess the tl;dr is "wait if I want to be this character so badly there is nothing stopping me from being this character (in the ways that matter to me specifically)"
Frost has a half-written essay on almost this same concept, but from the perspective of a kinda-fictive figuring out their relation to their source. I'll have to bug him to finish it
