In this story, Doctor Who is delighted to be reunited with giant green space penis Alpha Centauri. They are friends from an earlier, much better adventure, where they had a fun time drinking wine, wearing expensive cloaks and watching lots of other aliens get murdered.
You can tell from Doctor Who's face that he loves standing next to Alpha Centauri. He can be as weird and offensive as he likes, and he'll still be the one who doesn't look like a massive pulsating phallus in a charity shop dress.
The Ice Warriors are back for this story too. They look brilliant - all majestic and hard and like they'd win at anything that happened next, whether that be an orgy, a thermonuclear war or a game of Connect Four.
Alpha Centauri is clearly feeling a number of emotions.
His face - in as much as it can be called a face - suggests that he is thinking back through the events of his life and realising how different they would be if he looked more like an Ice Warrior and less like an intergalactic sex toy.
There is a villain in this story, and he's pretty good. He's called Eckersley, I think, and he's ever so cool . Look how he's just ignoring Doctor Who and carrying on with his evil plan.
Usually when Doctor Who stares like that at the villain, they give up and say sorry. The fact that Eckersley hasn't given up has rather spoiled things for Doctor Who, as he has no follow up. He's just going to carry on staring, I think.
Look at Sarah Jane go, though. Jo Grant would have been in tears by now, or fallen in love with a prince or been captured by dogs or something. Not Sarah. She's yelling, "Stop your evil plan, right now, you badly dressed ponce!"
He does stop, eventually, though I can't remember why. I think he tries to use a big gun and it explodes or something. Doctor Who claims credit, obviously.
Once the story is over, Sarah finds the Queen of the whole planet and spends ages telling her to sort her life out. Her main recommendations are:
a. Stop inviting killer aliens to invade you
b. Get a better hat
c. Don't let men tell you what to do - just shout at them and they will cry
d. If a giant green space penis asks you if he can come live here, forever, say "No."
