[He knows it is asking a lot. He does. But he's put Roy through a lot and he doesn't want to add to it if this crazy line of thought of his doesn't pan out. Because there is every reason why it shouldn't pan out. And he knows better than to wish or hope but it's just so goddamn hard not to. He sighs, deciding to just try laying it out in a way that might make sense. He's a logical man, so sometimes it helps to lay the pieces out like a puzzle.]

You and Roy were stuck in a place like this before and you've been with this Witch for awhile now as well. People are brought here by her, but sometimes they go home right? For example, while we were in Struxta, Keith and Shiro both apparently returned home and came back with a lot of time passing for them but not us. Do you know how much say or control she has over that?

[He waits for an answer, wanting to test the waters first before taking the plunge on where he's really going with this line of questioning. Of course, Riza's an intelligent woman so she may get there before he even says it.]
