There was too much satisfaction in Gamzee's expression as he looked to Karkat. He had predictably exposed himself, predictably let his anger take control of himself. He attacked Gamzee, and Gamzee allowed it. Not moving out of the way, letting the other troll strike him. A step, and another back. Letting himself take in the feel of that fist against his abdomen. His smile never faltering. His gaze never shifting from their transfixed position on Karkat's face. Even if his weak human muscles ached from the spot that was stricken, he didn't show it. There wasn't even an ounce of weakness revealed to Karkat.

"What's the fuckin' matter my brother? ARE YOU MOTHERFUCKIN' BOTHERED BY SOMETHIN'? I can't imagine what could ever be all up done be the problem. IS THERE SOMETHIN' ON MY MOTHERFUCKIN' FACE BROTHER?"

He takes a step closer, his movements slow, but it had an obvious deliberateness to it. As if holding back, as if trying to psyche the other out, mess with him, something. He wasn't about to strike him, not yet. No, the brother couldn't be spoiled yet. That would take all the fun out of it.
