Seamus frowned at that - and at the tears shining unshed in Dennis's eyes. "You don't?" That he couldn't understand. Paden obviously hadn't been good enough, if he hadn't valued Dennis then he was an idiot and the fact that he'd had no problem with infidelity meant he was a prick into the bargain. "What, ever?" Seamus had never had a relationship serious enough that he'd been sad to lose the person themselves, he'd only ever missed the hope that he might finally... He pushed the thought away, focusing on Dennis.
Seamus's flush darkened and he cursed - not for the first time - his Irish complexion. "Why do all my friends have a Seamus-got-laid sixth sense?" he complained, though he was laughing as well as blushing. "Alright, yes, I have - but it was over a year before that. As you were all doubtless aware."
Dennis somehow got his hands free and Seamus was all but ready to give himself over to being tickled - when Dennis pushed his shirt up. Seamus bolted upright, pushing it back down and going pale, his mouth pinched. "Shut up," he hissed. His eyes darted around the room like a nervous prey animal. Susan, Dean, Ernie - all fine, but fuck, Bryn was here too and Dennis and now everyone was staring at him. He could feel the weight of their eyes and he forced himself to laugh - a sound that got stuck in the back of his throat.
It wasn't just the scar, though that was bad enough, it was his own overreaction. Dennis's words were running on repeat through his head and he couldn't decide whether they sounded more like mockery or pity, or which was worse. He glanced to Dean, to Dennis, back to Dean and finally back to Dennis. He should offer some kind of explanation - but the last thing he wanted to do was talk. "Need the loo," he muttered after what felt like an hour - and walked off before Dennis could react, his shoulders stiff as he held himself back from running to the door and slamming it behind him.
