Sure, Steve needed to study his Astronomy, but really he just wanted to get away from his dorm and breathe. He makes his way up the Astronomy tower with his notes and sketchbook in hand, doing his level best to not think of Transmutations and spells against all manner of dark creatures, while his familiar (a huge, fluffy cat) is close at his heels. When he sees Jane, he feels for a second like he's intruding, but he's made it this far, no need to leave now.

Unless she asks that is.

"You look like you found a good spot," he smiles coming to sit near by her, but by no means crowding into her space, his familiar keeping post by the stairs, "catching some moon before the night is out?" He's aware it's a bad joke, didn't stop him though.
