Jamie shakes his head, a little mm-mn sound coming from his throat. He's got too much energy built up inside of him, and too much energy means he can't sleep, and he really tried to keep himself from waking Jon, but, clearly, that didn't work out for him. He's looking out the window, unsure of what time it is, but it's still dark enough to be... well, dark. The middle of the night. Jon should definitely be asleep. So should Jamie. "Sorry, didn't mean t'wake you..." he mutters, rubbing a hand over his jaw. "Y'can go back t'sleep, I... I'll just..." he gestures towards the door. He'll be fine, he will, it'll just take him a bit longer to fall asleep, and he doesn't want to interrupt what sleep Jon needs.
