Steven is initially just regarding Joker warily, like he isn't sure about what he's selling. He at least seems like he's going to refrain from being actively violent - that is, until Peridot starts going off on him, like she's the boss of who he is and how he feels. He jerks away like a vampire from the sun, jumping off the leaf just as the two of them get onto it, lifting himself into the air on wing and looming ominously.

His emotions are spiking even more violently than they have been the last few days - something about the concert being so near has him completely on the edge, and it seems like Peridot might be positioning herself to push him right off.

"DON'T TELL ME HOW I FEEL!" he practically screams at her. His voice breaks with frustration and helplessness. His vine arm is growing long and cruel looking, in a way that will be particularly familiar to Peridot.

"It's too hard!" he pleads. "I can't do it anymore."
