Rey would be lying if she said she hadn't thought of that possibility from time to time. It's just something she'd rather not think about, considering who has gone home and who could leave at any given second.

"Was sent home and came back before. Have known others who have also come and gone and returned again. Sometimes after a few months, or days," she replies, nonchalant. Then, she's more sincere. "But you're right -- we don't always know if that's the case for everyone. Even some people who come from the same world can go back to a different timeline and outcome."

Not the most comforting, is she?
