Everything comes full circle in the season 1 finale of In the Flesh. Episode 1 ends with Bill Macy pointing his gun at Maggie Burton, a harmless old woman and PDS sufferer, and pulling the trigger. Appeals to his humanity don’t sway him, but he does have Maggie take out her contacts so that he can see that she’s partially deceased while he shoots her.
Episode 2 ends with Bill’s son Rick Macy pointing a gun at 2 feral PDS sufferers, and then at Kieren, when Kieren steps in front of the gun to stop the unjust killing. Rick refuses to admit that he’s a PDS sufferer, but he does respond to appeals to his humanity. He gives up when Kieren takes out one contact to remind Rick that the feral zombies are the same as Kieren.
Episode 3 ends with a third person looking down the barrel of a gun, but this one knows he’s on the side of justice, and doesn’t hesitate to fire.
There are several moments of truth in episode 3. Bill decides that Rick must redeem himself by killing Kieren, who he says is a disgusting, evil rotter. Rick decides to prove to his father that PDS sufferers aren’t evil by forcing Bill to face that his son is one. Bill draws the opposite conclusion from this.
