Katie's anger only seemed to draw out Oliver's own anger. He supposed for the moment it was a relief from the sheer amount of embarrassment he'd been feeling since Katie had run into him. "I'm the damn captain for this team, I have every right to be here!" he shot back, irritated that he was getting grief for putting in 110%. "And I don't see why my appearance relates to this situation or how it's any of your damn business anyway." Seriously? What the hell had that comment even meant? There was nothing wrong with him.
In all honesty, he really didn't understand why either one of them were making such a big deal out of this. They'd been friends for so long and had played on the same Quidditch team (therefore sharing a locker room) on and off since they'd been in school. They should have been able to handle this like mature adults ... the fact that they couldn't? Well, Oliver couldn't really wrap his mind around that which didn't help his irritation all that much.
It really was no big deal. So what if he'd seen more of Katie then he'd ever thought to before. It wasn't like he hadn't seen a naked woman before. "Just-" he waved toward the shower, before stepping around her and heading to his locker. "-go shower." He intended to put clothes on as quickly as possible. Standing around naked was clearly bad for his mental stability.
