Doctor is distracted when Greg first wanders into the living space where he's practicing spells. Currently a plastic cup is doing something that resembles break dancing on the table in front of him. Doctor switches several times in one minute between looking amused and pleased with himself, and shaking his head, "No. No. This won't work." He ends the enchantment with a wave of his hand and finally looks up at the other person in the room.

It takes him a moment and then he hesitates just in case he's mistaken, then nearly shouts out his recognition. "Greg! You're all beardy now!" He gestures at his own chin.
