"Turning into a magpie, then?" Fortunately, he doesn't seem inclined to grab for Childermass again, even though his gaze snaps greedily to the necklace dangling from his fingers. While it would be nice to think it's simply because the knee was a permanent deterrent, a brief consultation with himself and the new, strange urges he's found rising in him suggest it's only because Childermass has successfully 'won' the necklace back this time that he isn't attempting to grab for it again.

Though if he should misplace it... well, Lambert won't be held responsible for that. He ruffles Baker's fur idly, considering what the magician's just said.

"Can you stop yourself from doing it?"
