That is so entirely fine with her.

Eventually a night watchman comes around bearing a lantern and coughs at them.

But they are busy.

"Don't you two have class in the morning or something?"

"Fine, fine."

"Awww. ...He's not wrong, though, I guess." She sighs. "Fly you back to your dorm?"

"Yeah, thanks."

She knows where everything is well enough that the darkness isn't a serious obstacle. "See you tomorrow."

"See you!"

And sleep. And learning!!
