You were very badly emotionally neglected as a child. It has had some effects on you as you became an adult. Said effects were becoming a bit more obvious to your captain as time goes by. He couldnt blame you. Your short fuse, cold disposition, and a plethora of other things. It was just a reminder of everything your parents failed to do for you. So he was trying his best. Watching movies during rec (even if he didn't understand some of them) or keeping an eye out on you during missions.
