In G ending, Carrol and (likely og) Alice's soul were reunited, so make that as you will (altho Grand Guignol happened so idk).You don't have permission to view the spoiler content. Log in or register now.
In H ending, Grimm seems to be determined to be reunited with Prickett/Alice from "Tea Party for Three" which would probably be a major plot point in BS III.
I personally believe og Alice were somehow involved even after summoning TCO, cause of the scene at the G ending. There is no solid evidence for it, and I could be wrong, but maybe more about it will be explored in BS III.
