Julius has never flown before, and it is... somewhat distracting, so he's nearly startled when she finally speaks. He doesn't physically start, but she can all but feel him reining his attention back in from the view below.

When he does, though, he gives her a serious answer. "I am hoping she'll let me stay long enough. I intend to try, at least." A pause, then: "You two are close?"

It's not accusative. Of course she wouldn't have mentioned. That's what they're discussing, in a way.
