She's not nervous, just evasive. Why would she full on accept blame when she knows the dude's not happy about it and she's probably in trouble? Stupid move. Kenzi's main thing is avoiding trouble entirely or knowing how to get the hell out of it before shit goes South.

But now she's getting defensive. She'd never ruin anything intentionally. Whatever she did was accidental, but the boundry issues clearly override any explanation she could even muster. Her expression sits somewhere between a pout and a scowl as she shrugs, "What's wrong with reanimated rabbit skeletons? It's probably the best pet you could ever want. You don't have to feed it, it would look totally cool, and it wouldn't have to fear predators if it gets outside because who the hell in their right-animal-mind is gonna mess with a freaking rabbit corpse? No one. I'd name it Nigel and it could live in my room and then you wouldn't have to worry about laying around on dishes I was gonna do later anyway."

Yeah, she's being really immature about this, but no one ever said she was mature in the first place. She rolls her eyes, picking her comic book back up. "Fine." So much attitude, Kenzi. But she attempts to make amends by adding a huffed out, "Sorry." Slightly less attitude that time.
