He was... too kind.
What sort of person took her, Dominique Screw-Up Weasley, seriously? No one ever had before. They always chalked up whatever she said to being a result of how weird she was, assuming she could never really mean anything. She was goofy Dom, stupid Dom, burnout Dom, naive Dom. She had always been too stupid, too goofy, too intoxicated, too young to have anything worthwhile to say.
But apparently, Declan Arryn didn't get the memo that Dom Weasley only spouted nonsense. Or if he had, he had chosen to ignore it. Why would he, of everyone else, decide that her words had value? She didn't have a track record for being reliable or unbiased and Declan knew her in her horrid twisted-thinking glory. He had seen the side of her that wasn't to be trusted because she didn't even know who she was or what she meant. He, of all people, should have been suspicious of her intentions.
It just so happened that this was one of the few times that she was right, one of the few things that needed to be heard. And only Declan would have believed her.
The problem with Declan wasn't that he was too traditional, or he didn't share her vices, or that he was a few years her senior. The problem with him was he was kind, and gentle, and romantic, and well-meaning, and he stuck to his decisions. Meanwhile, she was coarse and nontraditional and lusting and so inconsistent. She was exactly the sort of person that would break his heart and disappoint him. And, even worse, she was beginning to realize that she really liked him.
He pulled her into an embrace and she let him. She inhaled his scent, her arms reaching up to rest against his shoulders, thumbs brushing across him. She nuzzled her cheek against his chest, sighing as she squeezed her eyes shut. She knew there was something in her, developing a strong desire... and she rarely gave up on what she wanted. Still, her own knowledge of herself knew that she should have more restraint, should choose the easier solution.
But that wasn't going to happen.
He mentioned Roxi and she wanted to laugh, but she couldn't. Not when she knew Roxi. Slipping out unnoticed was the best solution, but Roxi would find a way to punish her, and probably Declan too. She just clung tighter to him, trying not to reveal the healthy fear she fostered for the brunette waiting back in the bar.
He stepped away and she watched him nervously, her large eyes still full of worry and uncertainty. He seemed like he wanted her to join him, but wasn't certain enough to ask. He looked to her and she nodded in affirmation, taking a step forward before taking his hands. "Let's go."
