Adrian was indeed napping. It wasn't that he didn't have his own place, rather he was keeping his head low after the altercation with Warrington over the return of the other wizard's wife. Yes, better to lay low.
The cottage had been deserted when Adrian arrived, two bottles of wine and a bag of sandwiches under his arm. No doubt most of the Renegades were enjoying a little time off after a rather successful kidnapping spree. He tended the fire place, uncorked a bottle and demolished a few sandwiches, enjoying the peace and quiet. Then he'd sprawled out on one of the overstuffed sofas, boots tucked neatly to the side, and drifted off.
