You two were bored as hell, just being goofy as y’all waited for someone for a mission. He decided he’d start messing with you some. He’d tap your shoulder, pointing to some place in the alleyway as he’d ask, “Hey, isn’t that the person we need?” Then, as you looked that way, he’d wack the living daylight out the back of your head, bursting out laughing at the loud ‘thhwwap!’ the hit made, also at you whipping your head around back at him.
