Don't mention it. [she doesn't quite get all of it really, but enough to spot errors when she sees them. What the woman wants to do is impressive and she can see the Professor getting up to something like that too.]

Fun. [she grins, wondering if that's all that is] I dunno, I've wandered through here for a few hours. I think it might be some kind of pocket dimension. It might have an end but you might never find it. [she takes another bite of her sandwich]

Everything else on board so far seems normal and fixed, so that's why I think this may be elsewhere or some sort of ship inside the ship or something. Haven't seen any controls though...
