By now, Thor knows where to find Jane when he cannot see her wandering the halls or enjoying meals with the rest of her house. With a castle this huge and them being in different houses, it's not as if he's constantly bumping into her. HOWEVER, he's both found her and been invited up here to see the stars enough to notice the trend.

Of course, he doesn't actually have a particular reason to be looking for her. He doesn't have a pressing question or something to tell her, sometimes there's just a passing thought in his head that tells him he wants to see Jane and very often he acts on it.

He's not quite as he thuds up the stairs, hell he's making so much noise you'd think they were herding cows up here. Jane will probably not be surprised when he pokes his head in and beams at her, proud of himself for finding her.

"Jane! I knew I'd find you here!" Now he's going to trot over and flop himself down next to her without inviting himself.
