Despite the fact that he deserved far worse than that, Barty's grin faltered, his eyes falling to the ground. If he kept them on her in that outfit, he'd be distracted from why he was here, why she was mad at him. She'd never been this angry with him before, but then again, he'd never done anything to hurt her before, either. He was currently mentally thanking himself for having such strong will against temptation, else him even being here would have been a slap in her face. As it were, his only transgressions were in his head, and in the way he had not been here when he should have been.
He was not so naive as to think that everything could be fixed right here and right now. After all, he knew there would be a strain between Rora and Bayleigh for a while to come, if Rora even chose to stay with him. And he couldn't very well continue on lusting after anyone but Rora if he chose to fix this thing between them. There was a lot that needed to be fixed, yes, but tonight was a good start.
Her tone, however, clued him in to the fact that whatever he was trying to do, he needed to do it now. There would be no dancing around the subject without her kicking him out before he got around to the real reason he was here. The necklace had not been intended as a bribe, but he could not deny that it had stemmed from his own guilt over everything that had happened in the past months. He glanced back up, eyes catching hers and zeroing in. In a voice very much his own, without pretense or expectation, he said, "I'm sorry, Rora." If that was not a sign of how vastly he knew he had fucked up then Rora didn't know him at all. On the contrary, though, Rora knew him best of all.
