In her infinite talent, Peridot somehow manages to make a distressed sound that is both nasally and guttural at the same time which, persists for the duration of the mussing. The gesture catches her by surprise enough that she freezes up at first, but then she's flapping her hands at his hand with an indignant snarl, trying to shoo him off.

"You know what I meant," she huffs, scowling at the other supervisor and running her claws through her hair to try and tidy it back up. It's weird, though... annoying as the gesture was, it also isn't entirely unwelcome? It's almost... comforting, in a way that Peridot really needed.

Not that she's going to tell Lambert that, because she doesn't want to encourage him.
