New Revelations: Time Shenanigans

[Fenral]

I feel like the "optional-ness" of the Crystal Tower storyline is a barrier to getting young G'raha reinvolved. For story-structure reasons I think he has to remain in the tower until some point beyond the game's time bubble.

He easily falls into Esitinien territory at this point, and can use the extra Alisaie handwave of "I've read so much about you that I feel I know you already." And let us also never forget that Urianger (and by extension Alisaie and Alphinaud) can now literally be in multiple dimensions at once. Though that could just be an Elezen thing.

Exarch's last line of 5.0 is "This is no time to be sleeping, G'raha Tia!" and it comes after a long interior monologue in which he realizes his dream is within reach but he can't journey to the Source himself. I think there's only one real interpretation for that. He's also vague enough about his origins if you haven't done CT, such that Source!G'raha could simply be treated as if he was sealed in beforehand without changing too much (though he would presumably still know Krile).

I had completely forgotten about Old Spock and Young Spock, but I now have a feeling that is what they might go for, assuming opening CT on the Source doesn't break the last bit of causality holding him in our timeline.
