Seamus was just mulling over Charlie's last words when he spotted Dean. Relief flooded him, easing every tension he'd been aware of carrying, and several he hadn't even known about. It was irrational, he'd known Dean was alright - could recognise his handwriting anywhere. Still, knowing a feeling was irrational didn't necessarily stop him from feeling it.
"Hey," he greeted back, resisting the urge to reach over the bar to touch and make absolutely sure Dean was really there. "I'm not really working, you want to head upstairs?" He shot an apologetic look at Charlie. "We can talk about this later?" he suggested. "Give you time to think about it, then if you've got any questions." He shrugged, not sure how familiar Charlie was with LGBT clubs or the scene in the wizarding world.
