The Doctor watched silently as the sonic screwdriver disappeared into the Master's pocket. He hadn't really expected the other Time Lord to just return it to him, and would have been suspicious if that had happened, but all the same there was a sinking feeling in the pit of his stomach at seeing it vanish from sight. It wasn't going to be easy to reclaim it now, though at least the Master hadn't broken it or tried taking it to pieces for parts. At least there was the chance that he could reclaim it.

"No, not conventional at all, is it?" he agreed. "You're not really the Housekeeping type." The House of Oakdown must have been in a bad way indeed to form that sort of link with a male Gallifreyan, let alone someone like the Master. Something else that backed up the other's comments about the House's sanity.

"But if you're connected to the House, then you share a psychic link..." the Doctor continued, musing aloud to himself now. The question seemed like something obvious, but he needed to hear it from the Master.
