Last week, after a demonstration with a balloon popping unmercifully, Carol was pushed into an airlock on board the space rogue’s space ship. The deal was that Peter – guardian of the time lanes – would show Jedikiah how to use the beta wave and travel in time by himself or Carol would be depressurised to death in the airlock. Carol made a brave show of defiance, telling Peter not to give in to the pressure (ho ho ho – just my little joke) but he was on the verge of cracking.

"Yes – I’ll tell" bleats Peter after literally five seconds of Carol making bloated and woozy faces. Is it me or has David Prowse got glittery nipples?

The airlock is open and Carol swoons out.

Back in the lab they – that’s Stephen, John and TIM but not Ginge or Kenny – are having a technical discussion. The time drift theory – which sounded nonsensical last week – has a new twist. Matter, proposes TIM, will drift in time while in hyperspace but always return to its own time when it leaves hyperspace. So hyperspace now has an administrative department does it?

Jedikiah decides that the medusa – star of "The Medusa Strain" – is no use because two telepath minds are too strong for it. So he invents collars that will suppress Carol and Peter’s powers without the need for a plastic octopus that looks like its trying to mate with an apple.

TIM is explaining that the government have COVERED UP~! the recent time freezing episode. The Beefeater who saw Stephen has been subjected to a number of tests because they think he’s a loony. Stephen feels sad for blighting the career of a man who had his whole life ahead of him.

Stephen and Kenny jaunt off to the Tower of London to look for clues.

Ah ha – they’re not new fangled collars – they’re the same silencer hats Jedikiah used last time. They are placed on the blonde heads of Carol and Peter. Sucks to be them.

Meanwhile, at the tower, a demographically correct group of bored children look at what they think are the crown jewels. Ha – stupid brats – they don’t know they’re fake. Ha ha ha. They’re wasting their boredom on plastic and tin.

Stephen hasn’t worked out that they’re fakes. He’s literally baffled by there not being empty cabinets on display. It’s the same Beefeater on duty by the way. He’s been tested for insanity and put back on duty the same day. They must be really short staffed. That’s probably why, a mere thirty years later, they started resorting to women to beef up the numbers (GEDDIT~? Beef up the numbers? I’m wasted.)

Stephen and Kenny behave in a hugely suspicious way by examining the floor right next to the Beefeater. John said not to draw attention to themselves. They must’ve been thinking about boobs during the word "not". They are teenage boys after all.

They have found diddly squat all and go back to the lab. The non-speaking Beefeater earns his non-speaking fee by expressing his suspicion that he’s seen that boy before somewhere.

On board the ship, Jedikiah orders Peter to adjust the time key so he (Jedikiah) can use it. Peter says he swore an oath to die before he did such a thing. Jedikiah orders the android to squeeze him a little. He then threatens to kill Carol if Peter doesn’t cooperate. Interesting fact from the commentary is that Peter’s dad in real life wrote the massively overrated Alf Garnet series.

Peter says he can’t do as Jedikiah asks – he’s abandoned his moral objections by the way and moved on to more practical concerns – with the silencer on his head. Jedikiah reluctantly removes it.

Peter sticks his hand into the globe thing to make the necessary amendments. While he’s doing that he takes the chance to send a speculative message to the Tomorrow People.

John receives it. Drama.

Somehow Jedikiah knows what’s going on and he violently puts Peter’s hat back on.

But it’s enough for John to know where Carol is – she’s in hyperspace. Erm, didn’t we know that already? John says he’s going after her. Stephen and Kenny want to go too. John tells Kenny he’s got to stay behind in the lab. Welcome to the rest of your television career, Kenny.

John and Stephen put their AE suits on, everyone wishes them luck and they are jaunted into the time drift zone.

The rogue is taunting Carol with his trinkets and his not-being-in-a-cage-ness. He hasn’t twigged yet that Jedikiah has betrayed him and locked him in the menagerie with the other prisoners. He still thinks that – because he’s got a crown – he’s top dog. Like Elizabeth II in fact who hasn’t noticed that she’s got less power now than Robert Peston.

It turns out he’s a sap born into a world of tomorrow people. He’s an oppressed minority. This whole thing is actually a racial parable. He even declares "I am a count" at one point. You said it mate (chuckle). Peter is thrown back into his cage and Carol tells him that under no circs must he give Jedikiah the secret of time travel. Peter looks so sad – he’s just given Jedikiah the secret of time travel and now he’s never going to get to sleep with Carol.

In hyperspace, the life force thingy is failing to detect life. Things are looking bleak.

Jedikiah’s plan is to send the rogue back in time to eliminate the Tomorrow People in the 20^th century while he – Jedikiah stays behind and operates the machine. The rogue suggests they swap and Jedikiah goes back because it’s his feud but Jedikiah says no – that would let the rogue sever the time bridge and leave him stranded.

He wins him over by saying that eliminating the TPs in 1973 could mean a 26^th century free from telepaths. The rogue’s time would be full of men. It is very homoerotic – every time Jedikiah says the word "men" in a dramatic way, the rogue’s eyes get brighter.

In the lab, Kenny and Ginge are filling time by playing a game to test Ginge’s latest telepathic powers. Can he predict which shapes Kenny is holding? No he can’t. Just like in Ghostbusters.

The rogue and the full sized medusa go through the time bridge. There is absolutely no way they’ll stand out in 1973 looking like that. None at all.

Ginge asks TIM to get him some cigarettes. TIM refuses. Smoking is bad, children. Even if the goodies do it.

The time bridge brings the bizarre trio to the underground near the lab. At least I think that’s where they are. Ginge has gone out for some cigs leaving Kenny all alone.

Ginge spots the newly arrived crew. He is appalled.

The medusa races after him.

He makes it back to the lab and warns TIM and Kenny that "Dracula and King Flamin’ Kong" are outside. Ginge is possibly the least witty person in the world.

Kenny can’t jaunt away and Ginge can’t use the stun gun because it’s on charge. Oh fiddlesticks – they’re done for.

Ginge hides Kenny in a cupboard and readies himself for a scrap.

The lab door disappears and the baddies invade the Tomorrow People’s secret HQ. They’re the second lot of baddies to invade their secret HQ in two stories. I think they may need to revisit the word "secret".

Ginge is being taken to the time bridge when he breaks free and pushes the medusa onto the railway line. It is electrified to death in a puff of smoke. Thank goodness one of the goodies in this story is allowed to kill things. This allows TIM to contact Stephen and John in hyperspace too.

Stephen and John return from hyperspace. They see the devastation. "Oh no" sighs Stephen. Yes – it’s that bad.

Jedikiah is not pleased – the rogue went back to invade the lab and brought back the only person there who isn’t a Tomorrow Person. I’d forgotten that Jedikiah used to employ Ginge and Lefty. Jedikiah is appalled.

Ginge is locked up with Carol and Peter. "This must be that spaceship they’re looking for" he says.

Back on Earth, first things first. Forget Carol and Ginge – they lab needs a new door. TIM, John, Kenny and Stephen concentrate as hard as they can and make one. DIY-tastic.

Recent events mean that TIM now has coordinates in hyperspace to aim for. Kenny asks if he can go with them. He can’t.

Hooray – they’ve spotted the space ship.

Boo – the space ship has spotted them too.

Jedikiah uses the big gun to shoot them.

They’re blasted to atoms. Sucks to be them.
