The whiplash of the mood shift made him laugh. That was just what he needed to knock himself out of his mood even though it would remain there, lingering like a black cloud. At first, he didn't move, just pushing his fingers through his hair as he thought and worked through shoving the rest of his anger in the mental box he kept it in though it strained and pressed like a jack-in-the-box waiting to explode at any moment.

Ariel stood slowly, deciding to slip off his leather jacket and casually drape it over the arm of an unoccupied chair. Part of him felt bad about the state of the wall and the sofa but Amadeus had said nothing and so neither did he. But the real question was - was he honestly going to take the Elder up on the offer even if it might have just been a joke.
He did approach, silent like the apex predator they both were. As casually as he could, he straddled Amadeus's lap with a faint smirk, just so he could be facing the Elder vampire as he draped his arms over the other's shoulders, "Like that?" He needed the distraction, desperate for anything else. Maybe Amadeus knew that.
