Well, Lapis would disagree, but Peridot is at least a close second, because no one is better than Steven. That's... probably not what Peridot really needs to hear about right now, though? So for once instead of making a smart comment, Lapis shuts her trap.

And continues patting Peridot as she tries to find something more helpful to say. "Everyone sucks at new things." Is the best she can come up with. "Besides, you got used to earth and this place a lot faster than me, and that's a new thing."

Honestly when the RM said she was human she's lucky Lapis didn't murder the shit out of her? It's probably a good thing that Peridot and Steven are her moral compasses, because whoa boy.
