It would have been unfair to Theo to say that he flinched almost imperceptibly (but not quite) as Dean's hand came down on his shoulder, but it would have been accurate. His fingers twitched like they wanted to go for his wand and he tensed up but managed to restrain himself because if he had drawn his wand and hexed Dean over something as insignificant as a pat on the shoulder he wouldn't have been able to live with himself from the embarassment. "I suppose." he replied, to both, but didn't make a move to leave himself.
