Alllllll right so after a really emotional ordeal at the Glass Workstation I've finally been able to compile my thoughts into coherent sentences, and something that was mentioned there stuck out to me.
I don't think Anna says anything if you took the Zekrom route (which I haven't done yet) and I'm not sure if she's there, but I took the Reshiram path, and as we all know Taka is unfortunately killed down this path. When you wake Anna she says something along the lines of "the boy with the broken wings didn't have to die...I can fix this. I have to fix this." or something like that. Considering the fact that we were saved from the void (and surmising that Cain is still stuck in there despite "dying" from the black hole), is it possible that the void is what is considered death in this universe? And, if we were saved and considering Anna's word choice, is it possible that Cain and Taka could come back? Both of them are dead (or at least one of them, if Cain isn't), but what really piques my interest is the fact that Anna said "I can fix this". Is it possible for her to bring Taka back?
I was really emotionally distraught after his death, so maybe it's just me clinging to hope, but what does everyone else think about her wording? Any theories or thoughts? I'm really interested in hearing what everyone else has to say!
