(1) Let's start with TV. All these shows have the word 'Two' in the title. What are we watching?

(3) People like movie sequels, don't they? And 'Part III' films, which they call 'threequels'. I don't know what the term is for films like Fast & Furious 8: The Fate of the Furious, and anyway - it's not relevant right now. Here are the subtitles of some 'Part II' films. What are they sequels to?

(4) Next time you see a turtle dove, admire its turtle-like plumage. That's how it got its name, right? Wrong! Turns out they're called that because they make a sound like 'tur-tur'. Turtles are a whole different world, with many species, often endangered. Below are ten types of turtle. Five are real, the other five I invented just now. So a point each time you can tell me: Shelly or Smelly?

SMELLY!

(5) Last time, when we did people with three-letter names, I said I didn't think it would be possible to repeat the trick with two. But, allowing the odd initial and numeral and animal and robot, I'm happy to admit I was wrong. Who are these individuals?
