When Colonel White says
Anything to report Lt Green
Captain Blue mouths the words along with him!
As Captain Black starts to follow Chapman, watch the side of the lorry. A fly goes past which would have to be the size of a characters head if it were to puppet scale.

Also the car that Mysteron Chapman takes from New York has the same registration as the car that vanished with Captain Black at the end of Heart of New York.

Correct me if I'm wrong but the plane with which Chapman flies to New York was previously the RTL2 freighter in the Thunderbirds episode The Cham-Cham.

it was and chapmans scream as she fell down the dam wall was very realistic

Yes - not just that but the actual shot of her falling was very well done as well.

And Scarlet shot her before she did that.
Unlike Model Spy, where he ran away.

The security guard was previously Orson in Lunarville 7. And once again he is unlucky...

And since when was LA only 30 minutes away from Arizona? ;-)

When the doctor was "activating" the culture, he poured a clear liquid into a beaker of red liquid, stirred it, then poured some into a test tube. The fluid in the test tube was clear, even though the remaining fluid in the beaker was red. Later, they show Chapman pulling the test tube out of her purse, and the fluid is red.

I wonder if that security guard actually died. Chapman didn't throttle him for very long.

It was very realistic for them to have "civilian" reports of Chapman coming from all over the country.

When Captain Scarlet parachutes down (and that must be unnerving, facing a gun with no place to run to) Chapman shoots him. We see her dig her hand into her purse. Scarlet lands on the dam. We then see her pull her hand from her purse, then insert it into a separate pocket of the purse. What was she digging for in the other pocket for so long?

Chapman is, I believe, the first Mysteron agent since Captain Scarlet to vocally react to an impending second death. (Heights must really bother them.) It's really kind of weird, when you consider that so many of the agents are sent on suicide missions--especially the ones who become walking bombs!

Captain Scarlet's sweating face, as he finally managed to retrieve the test tube, was very effective.

If you take Noose of Ice as being before this, then she's the third to die making noises.
Neilson was screaming on the stairs at the end.

Oh, yes, thanks.

He was being quick-fried, wasn't he? Don't blame him for yelling.

BTW, did Dr. Magnus yell when the same thing happened to him?

I think he did. Not sure.

Yes, he did.
