@Laughing_Snake : If she points it out, he'll probably care.
But that's the real issue.
He didn't notice, or rather he didn't think to check for injuries AFTER SHE JUST GOT KIDNAPPED.
He is basically all in the present, lacking both foresight to see how his actions (or rather, lack of reactions to other girls' approaches) might be taken, and the hindsight to learn from his 'mistakes'.
