Lol, yea it's pretty hilarious when he pulled out that gun and forced it to the barber's head. And it was pretty obvious it was going to happen sooner or later. Since he always does something like that to a civilian who has objects he might think to be dangerous. The way he acted was funny too, repeating everything over to make sure it's just that. Towel, towel, towel, towel, scissors, scissors, but we all know Sousuke can't controll his need to take out anything that might be a threat to chidori or himself.
I never get tired of Chidori bashing his head in lighting speed mode. Im guess even though they told Sousuke to not go near her, I believe that when Chidori is in trouble Sousuke will come to the rescue. Or he could just live his life in misery thinking of horrifying events that might happen to Chidori since hes good at doing that.
