Plot hole: When Kalgan is torturing Lea, he says that he wants her father's countermeasures in case of emergency. But when she is rescued and finds out MacPhearson is a traitor who is working for Kalgan, Captain Devers is worried because MacPhearson knows all of the ship's countermeasures. If MacPhearson knows the countermeasures, then Kalgon does too, so there is no reason to bring it up while he is torturing Lea.

Kalgan: It was cruel fate to be born in space, but I have vowed we will not die here. It is my destiny to set my feet upon a real world to accumulate wealth and power beyond our wildest dreams. I have offered the people of the Southern Sun a rich, new life, and now they have no alternative but to accept my generosity and alter course for Corona Borealis.
