For this week’s episode is called ‘Rogue’, and is named after the rather dishy swashbuckling bounty hunter who is on the scene at the ball, played by Jonathan Groff. He’s trying to capture the shapeshifters and beam them off to be incinerated, and mistakes the Doctor for one. So he takes him off back to his cloaked space ship in the garden (“My ship is behind that shed,” Rogue says, pointing to the TARDIS. “Shed?” says the Doctor, “That’s my ship.” “You travel in a shed?”), where the flirtation can begin in earnest.
