Declan looked up at her from across the room, genuinely listening to what she was saying - but at the same time, he wasn't really paying attention at all. Instead, he was too busy thinking about what had happened the last time they were stuck in a room together. Not that they had been stuck in the Room of Requirement, of course. But he wouldn't have left her there. And, beyond that, there had been such a moment that morning, where they had just sort of stared at each other before he turned away to keep from doing something that would make everything so much harder for both of them.
But there he was, looking at this wildly gorgeous girl, and wondering how he had messed it up so badly. Somehow, it seemed unlikely that anything else could have happened between them, though. Was there even one thing he could have said or done to make her think of him differently? He didn't think so. And that was a terrible, unfortunate thought. But what they both felt right now - that almost helpless and confused air that surrounded them? It was his fault, no matter what he wanted to say about what Dom may or may not have caused with her reaction to everything.
Declan had walked right into this one, had brought it upon himself. Because he didn't know her well enough and because he held on too tightly to his past regrets. He wanted to know her, but all he had worried about with Danica had nearly been topped by the blonde woman in front of him. Not because Dom was in any way a bad person, as he now realized Danica was. But because he wanted to be allowed to care for her in the way he had cared for Danica, yet he wasn't given that permission. He didn't know how to move forward from there. He had never known how to move forward with Dom, though, to be quite fair.
There wasn't a real reason to put stock in what he thought they could have if she refused to allow it. Maybe it would be better in the long run to just accept that it had happened and move on. It wasn't as though he would be asked back to Hogwarts in the fall. His lifeline to the school was leaving, and that meant he would, too. Even if it meant he wouldn't be around her in this setting again. Perhaps that, too, would be better for them. If they had just met one day in the Leaky, none of this would have happened. They probably wouldn't have been trapped in this stupid room, either. Peeves always did seem to enjoy messing with the ones who already had it rough, didn't he?
"Dom," he began finally, as though he were snapping out of his conflicted trip through his own thoughts. "I don't know if this is the right time, but I don't know what else to say. So... I'm really sorry. It seems like I say that a lot lately, but I am. I shouldn't have done anything. Not any of it. I didn't know you well enough then, and I still don't, because of what I said and how I handled it."
Shaking his head, Declan stuffed his hands in his pockets. "Dom, I'm leaving. I won't be back here in the fall."
