The body was tired, Jake realised. So, as he walked through the dorm hallways, he quickly ran through all the things he knew had happened ever since the last time he'd been in control, either from reading the messages on their phone or from what he could remember when he was closer to the front than not, to see what might explain the tiredness.
Marc had woken up, gone to classes and then gone to get a cookie and a lollipop with Mary and Eponine. Steven had done most of their homework already, and gone to see a movie? Well done, Mary, for dragging the nerd away from his books. Marc had almost freaked out about the idea of Layla getting into trouble - not that any of the adults here were like Her, but Marc was still convinced that all adults would either beat the shit out of them for, like, breathing too loudly, or ignore that it was happening in the first place - so Jake had taken over and gone to see what a blanket fort was like. Steven showed up after that and did some more reading for English, and then Jake had taken over again when Steven had dozed off at Layla's, and he'd been in control ever since.
So now, as a reward for so much 'having-to-control-the-body'ing, Jake was going for a smoke, despite how tired they felt. He'd checked his little stash when his roommate wasn't paying attention (only two cigarettes left, so he'd need to check in with Bev very soon) and then left the room, muttering some excuse as he did so. He was heading for the roof, and he would have one of his cigarettes up there, and then head back to the room after he'd had some time to himself (hahaha like he was ever alone), and then they could try and sleep.
