NOTE - Charles Tingwell and Paul Maxwell did not appear after this episode. Both are heard however in flashback during Traitor and The Inquistion

OK, I can accept that Captain Blue doesn't have Scarlets built-in mysteron sensor, but doesn't Brecks manner when Blue comes in after the reconstruction seem a tad... strange? He may as well have a sign above his head flashing "This is a Mysteron, and this Mysteron has obviously learnt the art of sticking close to idiot Spectrum officers who couldn't notice something wrong if it died right in front of them and sat there rotting for five days."

Why do the Mysterons sound like they've been sucking on helium?

Imagine : you are a scientist, and you and your fellow scientists have been working on something for a very long time. Your two fellow scientists (I'll call them Wilkin and Maxwell, and I'll call you Tingwell ) look and sound very happy when your project finally succeeds. What do you say, after :
Wilkin : We've done it!
Maxwell: Wonderful!

'Hoorah!', perhaps? 'Yippee!', maybe? An 'Excellent!' worthy of a Cyberleader? No, you say :
Tingwell : 'Well, we've succeeded.'
I'm sure you're smiling inside, Mr Tingwell. You look and sound utterly depressed.

>Both are heard however in flashbacks during Traitor and The Inquisition<

You also forgot Dangerous Rendezvous Tingwell said "There hostile."
In Captain Black's mind he must of thought "DUH!"
But amazingly they were both wrong.

Oh yes.....the whole series shows how thoroughly unhostile the Mysterons are....

My personal least favourite episode - although it's got a few nice effects the plot lacks any weight. And Breck's first death lacked all impact (that silly shining light effect didn't help either).

Very melancholy touch at the end, with the camera probe dutifully sending off its signals to a station that can no longer receive them.

I don't think that Scarlet should have made the flat statement, "No one could have survived." People have been known to survive the most extraordinary situations.

And why didn't they have a method for communicating with the station from the outside? A walkie-talkie or something? If they could have warned the men instantly, they just might have made it out of the building.

For that matter, they could have had Melody broadcast a warning from the helicopter.

The whole situation was handled badly. Once they decided that Breck was a Mysteron, they decided that their priority was in capturing him. They should have considered what he was likely to do to foul up the works, and conducted their search accordingly.

They've got their mini-sat, and it will be transmitting for an indefinite period. What's wrong with rebuilding the station and obtaining the info?

We're left with that tantalizing reference to "Operation Sword", which is never heard from again during the series.
