It's some combination of Tybalt sparing him the laughter that his total lack of suaveness deserves, paired with his absurd feigned jealousy over the minion, that brings something of a smile to Eddy's face. Or maybe it's just that ridiculous brave new world pose. Eddy's mouth doesn't twitch much, but it's there in his eyes. "Saying you don't have what it takes," he asks, playing along better now that the initial wave of panic has passed. There's just a touch of soft smugness to his tone, enough to poke lightly at Tybalt's ego. Though he's still very much keeping his hands and his leaning to himself because there is absolutely no need for a repeat of that.
