In The Face Behind the Glass, The time for final stage of Delilah's naming ceremony arrives. Russell invites Delilah to the stage. Before going in, Delilah gets a little scared and returns to Jordan. She gives him a kiss and asks him not to let her be another face behind the glass. After that, she goes to the stage and enters a room. Some time later, she comes back outside, as Priya the Seventh. Jordan is shocked when he tries to talk to her but she doesn't remember him. She is acting like a completely different person - Priya.
In The Gospel of Josephine, Priya is talking to Miranda about the things she missed while she was "on ice" and says that she is sorry for Rose's death so Jasmine could not be resurrected. Then Jordan walks up to them. Miranda explains the he was Delilah's boyfriend and he gifts Priya daisies, mentioning they were Delilah's favorite flowers. Priya out of courtesy accepts them and thanks Jordan, saying that they are. Delilah's favorites had been calla lilies, so this "confirmation" of the daisies heightens Jordan's suspicions about Priya and the Primes.
After figuring out the bodysnatching, Wonkru members talk in the tavern when Priya comes in. Jordan freaks out, saying that they murdered Delilah, pointing out to Blythe Ann and Jae that she was their child. B.A. says that she misses Delilah too, and Priya calms Jordan down saying that Delilah is happy and she wants him to know that.
In The Old Man and the Anomaly, everyone has gathered in the Palace after Miranda's death. Madi sees it as an opportunity to kill more Primes, starting with Priya. When Jordan notices Madi about to stab Priya with a knife, he jumps in to save her, but Madi accidentally stabs him instead. While everyone else suspects the Children of Gabriel, Russell says that it was the group from Earth that killed Miranda. Priya wonders why the Earth group would turn against them since Jordan just saved her. At that point, Ryker reveals that they did it because Russell "murdered" Clarke to bring Josephine back. Some Primes are angry that Russell brought Josephine back before it was her turn.
In Ashes to Ashes, Russell tells John Murphy that Jordan survived his wounds and was spared punishment due to his saving Priya. Priya has been personally seeing to Jordan's recovery in thanks.
In Adjustment Protocol, Priya prepares for the Naming Day celebration in Blythe Ann Workman's tavern. With Echo, Gaia and Nathan Miller hiding behind the bar, Blythe Ann and Jae do their best to distract Priya so she doesn't find them. Clarke arrives posing as Josephine and claims that she needs her help with mind wiping Echo, as Ryker couldn't bring himself to do it. Recognizing that something is wrong, Echo instigates a fight, and Clarke knocks Priya unconscious when she tries to escape.
Later, in Ryker's machine shop, Clarke and her friends revive Priya to force her to help them to disable the reactor powering Sanctum. When Priya refuses, Clarke threatens to smash Ryker's Mind Drive with a sledgehammer to force her to cooperate. With their original plan having failed, Clarke decides to use Priya to spread the truth. Bellamy brings Priya in front of the crowd of Sanctum citizens and, holding Ryker's Mind Drive, compels Priya to reveal the truth about the Primes to the gathered crowd.
Once Priya has admitted the truth, Bellamy gives her back Ryker's Mind Drive. However, Russell initiates the Adjustment Protocol in retalitation, unleashing a massive amount of Red Sun toxin upon the crowd which goes mad and attacks each other. Separated from Bellamy in the chaos, Priya is confronted by Delilah's enraged parents. Calling Priya a murderer, Blythe Ann stabs her to death.
In The Blood of Sanctum, after the defeat of the Primes, Jordan confronts Bellamy about his role in Priya's death. Bellamy insists that the truth got Priya killed, not him. Jordan suggests that while Sanctum wasn't perfect, it was at least peaceful before they came along. As Bellamy walks away, Jordan looks at Priya's Mind Drive which he holds in his hand.
