Citadel on Prime Video season 1 episode 6 recap: Why did Mason betray the organization?

The episode begins with a flashback from an incident that took eight years ago. Mason is sent on a mission to infiltrate a nuclear submarine, he's shown to be using a stealth jet to enter the submarine.

Viewers again get transported to the present where Dahlia forces Kyle (formerly known as Mason) and Nadia to enter the submarine to retrieve the nuclear codes. Dahlia has abducted Nadia's daughter Asha and threatened to kill her if she didn't get what she wanted. Although Nadia wants to spearhead the mission, Kyle and Silje ultimately decide to execute it.

Kyle and Silje jump on the ship but suddenly the latter turns his back on Dahlia and threatens to launch the missiles towards the Manticore headquarters. He does so because he realized that Dahlia had killed his twin brother. This led to Kyle and Silje getting into a brutal fistfight but in the end, Nadia manages to get the codes with Carter's help.

Silje is neutralized and Carter, Kyle, and Naida then head to Valencia to retrieve Asha in exchange for the codes. Although the trio get into some trouble with Asha's captor, Kyle manages to save the day. A flashback then takes place where we are revealed that Bernard told Mason why Nadia vanished. Mason knew that Nadia had his baby but he did not bother the child's mother since Nadia didn't want him to be there.

Back in the present, Carter, Nadia, and Kyle return to Citadel. Carter injects Kyle with the memories of his past life and we finally get to learn who betrayed the organization; it is Mason who betrayed Citadel.

Dahlia once told Bernard that a backstabbing Citadel agent had approached her. It was assumed that it was Nadia, however, it turned out to be Mason. The latter needed Dahlia's help to locate Nadia. Moreover, it is also revealed that Dahlia was Mason's real mother; the former abandoned him when he was five. She even told her son that his father was killed by Citadel's error. To extract revenge, she convinced Mason to give her his organization's secrets.

In the end, Dahlia tasks Manticore to have all Citadel agents killed. Even Mason and Nadia are supposed to die but they escape. The episode ends with Abby asking Kyle if he remembered the past but he lies to her, saying that he doesn't remember anything.
