It seems as though he didn't check at all. He claims he thought she was in bed and so that whoever was in the bathroom was an intruder. Surely the first thing you would do is 100% make sure she was in the bed. Then if not, call out when you get to the door. I understand the arguments about being paranoid/skittish but I think in that situation my first thought would be making sure my girlfriend was ok/safe.
Of course we would check to see if our partner is in bed before shooting through doors. You would be thinking who is behind the door unless you didn't really care and knew who was behind the door? why not shout who there?
