"It's fine." Lambert does, in fact, want to sit with Childermass... so he'll pull up another chair facing across Peridot, where he can easily glance between her and the magician at the same time. He won't do anything so sappy as reach out and hold his hand or anything like that, but it's reassuring just to reaffirm that he's here. Not gone, not taken.

His gaze turns to Peridot again, watching her struggle with it.

"Sometimes you need time to sort things out for yourself." He pauses. "I told her you were busy. Figured you could talk to her when you're ready."
