 CONT: When Kalgan is torturing Lea Jansen, he says that he wants her  fathers countermeasures. But when she is rescued and finds out  MacPhearson is working for Kalgan, Capt. Devers is worried because  MacPhearson knows all of the ships countermeasures. If MacPhearson  knows the countermeasures, then Kalgan does too, so there is no  reason to bring it up while he is torturing Lea.
