Sometimes escape was needed, and this was one of those nights. With his pillows stuffed under his covers bewitched to move a little every so often and his invisibility cloak on, he snuck from his dorm slowly, careful throughout the common room since there was still a few people there doing homework.
The castle was lovely at night, not that he'd let anyone actually hear him using that word, but it was a completely different world when it wasn't clogged up with students.

He silently moved through the passageways, taking his time as he admired the quiet and the serenity of the historic grounds. Really, it had come to the stage that anywhere else was better than being in the dorms, what with his two best friends being all...into each other. He wasn't against it, per se, it was just his best friend was now always distracted by his affections, and although he was all 'good on them' for finally getting together after long last, it was a bit sickening to see then so affectionate, any couple got annoying like that after a while!
And really, it just made him feel lonely that they had each other, and that his affections were still un returned.
Still, he'd win her one day, he knew it. She'd come to her senses again, once she realised how much he had grown up and changed for the better, he was sure of it. You couldn't love someone this much without them loving you in return, the very thought of such unrequited love would force him to lead nothing but a half life, and she'd never do that to him, he knew it.

Slowly he pushed open the door, which creaked, hoping that no professors were around close by, monitoring the corridors. After a pause he started to make his way up the stairs, taking it slowly since the Astronomy Tower was well known for couples to go to in hopes of making out. As such, the professors made trips there a few times a night and if he bumped into one...well, he was Head Boy, it wouldn't go down that well, especially since school had only started last week.

He turned off before he got to the open area where you star gazed and where couples always went to, and instead paused by the door to the classroom, listening closely for a moment before he entered slowly, trying not to make a sound, although she was always distracted enough to ever notice he was there.
He tip toed in and lay down in the corner, well out of the way of where she was sitting on the window ledge playing the violin, the noise dimmed a little so she could remain hidden from the professors.

James Potter watched Lily Evans happily, resting his head on his arm as he lay, listening with half closed eyes. Music, especially when it was coming from her, was never better when it was music of the night.
