The Master sensed rather than heard the disturbance in the hotel lobby, and instinctively went to investigate.
He poked his head round the door and raised his eyebrows high at the sight of a dirty, wild-looking boy in very odd clothes (were those animal skins?), with a rather formidable-looking weapon aimed in the other direction.
The Master slipped through the door, leaned back against it and folded his arms. "Not where you expected to be?" he inquired lightly.
Yes, he was risking getting shot at by those stakes, but after the night he'd just spent with the Doctor, he was too high to care.
