The Master grinned beatifically at the Doctor's little conceding. He nearly swooned with it.

"Ahhh, I love to hear you say that..."

He swung around dreamily, oblivious to the Doctor's near-fall, and began to flip through the rack.

"Something comfortable, yeah?"

He was feeling rather chuffed with himself right now, for some reason. Probably thanks to replaying those words over and over inside his mind, savoring it, even if it was just a tiny outburst.

He came to a leather-vest-and-chaps cowboy ensemble, gave the Doctor a look, and kept going.

"Ooh look, thermals," he said as he pulled out a dark long-sleeved shirt.
