"Mmm, that is a bit different from my experience then," he agreed. "I don't think the Doctor ever needed me that much - not as much as I needed him, or as much as he needed you - and now he's regenerated he's. Well. We just sort of have fun together. Neither of us are that needy."
He didn't add that the Doctor seemed more needy about the Master than about him.
"I guess our relationship didn't change that much after he regenerated. Maybe yours won't either, once he's settled down and you've got used to the new him?"
