Wow, thank you everyone for all the wonderful responses! It took me a few days to thank you guys, due to my mind not being able to comprehend the whole "Mide-and-Dayan-are-just-there-it-can't-be-explained-ever" thing, but after rereading, it made a bit more sense. I'd love to just accept the fact that:

But I'm still really confused. Would it make more sense to just think of this part as an enclosed bubble kind of thing? Both you and Anony Moose said that we were all just actors playing our part in a script that was predestined and has happened over and over, and that somewhere out there, Mide could've lived her life out, and so forth. It's just hard thinking about that when I know there's an object she held onto (that Codex fragment from seemingly her encounter with our whole squad).

Sorry if I'm being increasingly difficult/overthinking it, but I really just want to understand my favorite story in the game T_T
