[Nico hesitates for a second - he knows he's the one who brought it up, but there's just this niggling voice in the back of his head that says he's not supposed to really talk about it, all the same.

He's been trying to ignore it, because the rules are different here, and Hanna's his inmate, anyway, and he probably should know.]

It's called shadow travel. You can probably work out how it works, [he adds, with a twist of his lips before he takes a sip.] I can get into any public space and also my current inmate's cabin, even if the door won't open. I just need there to be a shadow, somewhere. Size doesn't much matter, but bigger is better.

But I don't think it'll work after next month. Kinda like, uh, special permission from the Admiral while you're my temp, I guess.
