It took Jack a brief moment to notice the other mans arm. Or rather the lack of... He had seen Bucky around the hotel before and he didn't look quite like that. They had never really had any long chats before, but something was definitely off about the other man. More than just the obvious arm, his face seemed a bit more narrow. Was he one of the imposters? One of the replacements? Jack had a few choices to make. Either play carefully or just call him out. He was going to opt for the first one. See if he could get him on his own in the kitchens and maybe confront him.
Jack nodded. "I'm heading in that direction too. I'll join you. Maybe we can talk a little more about security around here" he offered. "There's bacon, eggs, hash browns and some really good coffee right now" he added with a look that said he was looking forward to his meal.
