aaron on the surface kind of seems like this cold, unfeeling man whos stoic and has absolutely no sense of humour. and to a point, he is similar, but he's caring and loving. he's a sweetheart, really.

he's determined and damn good at his job, but a lot of that comes from care for those around him, which he prides himself on. aaron's gentle and warm, despite how he portrays himself, even if that part's true.

so when he starts falling for the new, young recruit, it's obvious to everyone but you.
