Reegan defies assassination order

In the underground laboratory, Liz discovers the grotesque truth about the 'astronauts'—their alien forms exposed when one removes its helmet. Her horror triggers Reegan’s cold admission that he knew their true nature all along, revealing his calculated complicity in their captivity. The confrontation escalates when Reegan casually offers Liz a place in his criminal enterprise, framing Lennox’s murder as a 'vacancy' and her refusal as a death sentence. The tension peaks when Reegan takes a phone call confirming the Doctor’s imminent return, where he defies a direct order to kill the Doctor, instead asserting his own agency ('I’ll handle it my way'). This moment marks a critical fracture in the chain of command, positioning Reegan as a wildcard whose loyalty to authority is now subordinate to his own ambitions. The scene foreshadows Reegan’s betrayal of his employers and sets up the Doctor’s abduction, where Reegan’s defiance becomes a catalyst for the escalating crisis.
