Isaac had offered to pick up some sentry shifts. He was a raider but he'd done a lot of sentry shifts while they were on lock-down and he knew the ropes really well now. He felt like he owed it to the prison to do more, that and being in a tower most of the time meant he could just be quiet and pay attention to the job and stay away from most people. Only problem was that he was shit with a gun, he was so used to using his claws and teeth that he never really bothered to learn how to use a gun correctly.
He climbed up to the tower a little late and let himself in. On the way over he'd been distracted by the scent of Winston but he couldn't find the dog. His gaze slipped over Rogue as he entered with a mumbled "Sorry i'm late..." and moved to settle into place quietly. He didn't know her but that was probably better. But now that he knew he was in here with someone else, and a stranger at that, there was a tense awkward feeling. Like he should be saying something. He cleared his throat after a minute and looked over at her, hoping not to catch her eye.
