At the offer of assistance, Rosinante shakes his head and waves a hand dismissively. There's nothing Kuai can do, he's certain of that.

He gets a grip on himself after a minute or so mostly because he needs to breathe and the laughter makes it hard. It almost hurts, in fact. His shoulders slump as he takes a few steps back, falls to the ground, then gets back up. A long breath through his nose and out again seems to prove he can contain himself for the moment, and he drops the muting effect.

"I need to go. I don't... I can't control this," he manages, quietly, with just the slightest tremble in his voice as the laughter threatens to spill forth again.
