Oh yeah, this is the first time Fionna is meeting one of her alternate selves.
Come to think of it, as far as we know, Fionna is basically the only "girl Finn" as far as we know, and that's gotta be weird for her.
There's not a multiverse of Fionnas out there because Prismo only made the one. It's just a whole lotta Finns. Like, imagine if you got to meet a bunch of different versions of yourself and all of them were a different gender than you. That's make you ask yourself some questions, right?
