"This morning we heard the most terrifying sound in space, the Universal Plague Warning Signal." We presume they know about the signal from Maya or from other aliens they have encountered. Why do the Crotons use this signal when they are transporting a prisoner? Sahala could explain simply that the prisoner can control minds, but instead conceals any information, which encourages the Alphans to mistrust her.
Sahala appears on the Big Screen. In the reverse angle of Helena, we can just see the corner of the Big Screen - and it's showing the Alpha diagram.
The Croton ship lands on the Alpha launch pad. When the pad descends (middle picture) the boarding tube is standard for connecting to an Eagle passenger module. In the first and last pictures there is a new ribbed section which fits the profile of the Croton ship.
The first stretcher bearer has no commlock in the travel tube. He has one on his belt when he emerges from the tube.
When they enter the travel tube, Helena carries her helmet (the two medics don't carry helmets). It is a yellow helmet with orange neck ring. When they leave the travel tube, a helmet can be seen on the barrel inside the unit. It is a silver helmet with silver neck ring. It wasn't there before, and Helena does not have her helmet any more.
The silver suits of the stretcher bearers are different to Helena's silver suit. They look like the firemen suits seen in other episodes. They have normal spacesuit belts, while Helena's suit has no belt. Helena wears an ID badge, but the medics don't.
As Ed Spencer and Helena discuss Maya, we see through the observation window a blonde nurse sitting at the desk in front of the window. She stands and walks to the operating table, shortly before Helena and Spencer leave to look at Yesta. As they walk to Yesta, we cut to the main medical ward and see the blonde nurse sitting back at the desk.
As Sahala revives Maya from stasis, Maya's hair is different between shots. In close up, there is a curl of hair over her collar bone.
The Croton spaceship on the launch pad has a diameter not larger than an Eagle passenger module. The interior is much larger.
How did Clea remove her jammer? It requires a surgical procedure, which would be very difficult to do on yourself. After double crossing Yesta, Clea confesses all to Sahala. Would Sahala trust Clea enough to leave her alone - even if she accepted her genuine remorse - so she could throw herself into space? Perhaps Sahala isn't being totally candid about the end of the story.
Stun guns are normally held in their holsters with a small strap. Unusually this guard didn't use the strap, and his stun gun is almost falling out before Sahala snatches it.
Sahala steals a guard's gun, but Alan Carter disarms her and holds the stun gun for the rest of the sequence. The Alphans enter the Croton ship. A rear shot shows the guard's holster is still empty. When Maya and Helena find Dorzak in stasis, the guard stands in the background. In his holster is a new stun gun. Where did the guard's second gun come from? Thanks to Fergus.
As he asks Sam "you could jam that message if you had one of these implanted in your head?", Tony gestures with the jammer in his hand, raising it and lowering it. We cut to Sam, replying "Exactly". In this shot, Tony's hand is still raised, with the jammer visible.
Dorzak does not know how to transform, although when he commands Maya he learns very quickly (within minutes?). Maya is ignorant of the ability to manipulate minds (Mentor did not use it either). These formidable Psychon abilities seem to be easy to acquire, but not widespread among individuals.
When Dorzak commands Maya to teach him molecular transformation, he takes her head in his hands. As he does, we cut to another angle, but the cut makes him take his head twice.
When Dorzak surprises Alan and Sahala, he is able to command Alan, but has no control over Sahala. Despite this, he aims his gun at Alan. Sahala could have grabbed the stun gun.
