A little of column A, a little that he likes getting out of the house and isn't in any hurry to see what would happen if the Doctor tried Enfys' patience. (She still carries an ax.) He pauses, not turned fully back to the Doctor, and raises his hand. His wrist, complete with silver, irremovable band, is exposed. He doesn't say anything, but the implication - that he's trying to sneak up on a telepathic, omnipresent force (which has now heard him say it out loud, even) - is clear.
