Amethyst: You do realize we can just break these ropes right?
Garnet: And that I can just defuse to escape?
Pearl (muffled): And that Steven is still around to free us?
Jasper: HA! OFCOURSE WE DO! (Whispering to peridot) You did prepare for that right?
Peridot(also whispering): well to be honest, I was kind of hoping they would forget all that.
Jasper: Oh……..Lapis?
Lapis: Don’t look at me: I’m just here because you were going to kill me otherwise.

Either way, Lapis wouldn't approve.
In fact, she's out of character.
