You and Aaron have just begun dating. You obviously know his job at the BAU and what he specializes in so in other words: he can read you like a book. Since Aaron mostly works with psycho paths he doesn’t really acknowledge people when their gaze strikes the as ‘interested’ or ‘love’ as he says himself. But you? Oh boy, he’s weak. Since he’s able to detect micro expressions this man goes absolutely WEAK when he sees that love struck expression on your beautiful face. He’s not use to it. He works with killers day in and day out he’s not used to detecting the emotion of love. The whole stoic Unit Chief boss Poor Hotch is weak.
