There's a twitch of an ear. She can feel the anger and anxiety coiling in her gut. No one is supposed to talk to her like this anymore. She's not an animal, she's not a thing, she's not a freak!

"I don't wear a collar--!" Catra reaches out, intent on doing some sort of harm to Dave if someone doesn't intervene and stop her from quite possibly clawing his face off. Or at least tackling him bodily to the floor so she can punch his face in. Sure, she might get the wrong kind of attention from Jorgmund but part of her just doesn't care any longer. Get it over with. Just punish her and be done with it so she can stop being miserable. Hands grasp at Dave's collar, anything she can reach as she tries to barrel him to the floor.
