Sounds like an adventure. If Sora were ever to actually read a book that wasn't either nonfiction or something the Librarian suggested, that sounds like that could be pretty fun. Maybe in very small doses? Whoever they were before HYDRA, they sound like fun.

Sora likes that. He wants whoever the soldier is in the future to be fun. Or, like, happy, at least.

"I don't think I've ever read a book like that, but I'll help you find it. Maybe if I remember more space stuff, we'll find something else there." He hooks his fingers behind his head again as he walks. "I did a lot of stuff before - or, Sora did. Even if I never went to your world or met you, I'm sure there's something i did that must have been close to whatever you were up to before." They should keep sharing, is the implication here.
