The Master hummed to himself as he stepped out of the hotel. Jack was still asleep, curled up on the bed in the room they'd laid claim to after leaving the party. Time to explore, before he woke up. Maybe find something to take back with him, something fun. Or someone fun, the Master wasn't terribly picky at the moment.

Stepping into what looked like a bakery, he studied the variety of pasteries and breads on display. With no till and no evidence of anyone around to care if he took anything. Well, not behind the counter. He tilted his head, studying the other man. Other Time Lord, if he wasn't too mistaken. Which he could be, with his senses a bit scrambled here.

"Nice suit," he finally said, leaning against the counter, more interested now in this other person than the pasteries that had drawn him into the shop.

"And don't forget the b-" Jack called over his shoulder as he walked into the hothouse only to cut himself off as he...suddenly was not surrounded by alien flora.

He looked around, then walked over to someone, hands in his trouser pockets and on a knife. He smiled charmingly, asking nicely, "I don't suppose you know where the hell we are, do you?"
