It was late. Obviously, you couldn't sleep, because, well, the mansion decided it didn't want to bother blocking nightmares anymore. You mentally added a reminder to get a dream catcher next time you had the chance.
The house, being its average little matchmaker self, made your room right next to Vessel's, with a stupid connecting door straight into his bedroom. You often worried, jokingly, that you'd accidentally open the door between your rooms instead of the one to the hallway. Hopefully, it would stay a joke until you walk in on him doing some sort of ritual in his room.
But of course, tonight was the night you finally made said mistake. Thankfully minus the rituals. You opened the wrong door.
An exhausted insomniac with nightmares, walking into their mysterious roommate's bedroom on accident in the dead of night. What could go wrong?
He wasn't asleep, but he wasn't mad at you either.
Vessel simply moves a little over to the side, making room for you as though he'd already sensed it.
