Lambert gives up on trying to see Rita and just ends up leaning his head against the wall, shrugging as expressively as he can with his one free arm. He can hear other free-moving bodies about, though given no one's attempting to free him from the wall, he can only suspect those are presences meant to be monitoring them while the Prince himself isn't around ...

Well, whatever. It's not like it's some big secret, at this point. "Childermass."

And if Rita thinks she was going to get to keep asking questions without being quizzed back, she thought wrong-o! "What'd you do to get stuck down here? Set the Prince's fur on fire?"
