107 Doctor Who (The Androids of Tara)

Excellent, you're halfway there already, now the fourth segment can be found in—Oh you have? that was quick. Well, I’d better tell you a story about a prince and a princess then… He is going to marry her, but she isn’t her, she's her it, which only looks like her so he’s actually going to marry her it, only he isn’t because he isn’t him, he’s his it. He is actually being held prisoner next door to her, with both their it’s failing to it it off. When Romana turns up - looking exactly like her and her it - she has to pretend to be her. The actual her, not her it. Which is ironic given that she now has her own it (currently being set fire to by a dog). That’s the point when the it hits the fan. What's the Doctor up to? He’s having drinkies with royalty and getting completely it-faced. That’s about it, oh yes! The legendary Taran Wood Beast has a cameo appearance in this one but it’s quite brief; blink and you’ll miss it. No, seriously….blink and miss it, it’s for the best.
