Lapis gives a hum of acknowledgement, but considering what she's doing, it's not like she can verbally respond. She does, however, reach forward with one hand, sliding it along Peridot's arm to lace their fingers together, because if she remembers right, Peridot loves that sappy shit.

Lapis herself doesn't care too much for it, but it's something Peridot likes, and she supposes it's the least she can do for chomping down on her like that, even if it was in response to a very rude comment.
