After Eve and Villanelle's exchange on the bridge, Eve is on a revenge mission; Villanelle finds a brand-new community in an attempt to prove she's not a monster.
In Russia, an operative on a motorcycle storms into Konstantin Vasiliev’s office, where he’s an elected official now. The biker beats up a bodyguard and then pulls a gun on Konstantin. She takes off her helmet and reveals herself as Eve. Eve shoots Konstantin in the hand and then demands to know where Helene is. He doesn’t know, but gives her the name of her last known contact, who’s now dead. He also wonders why Eve doesn’t ask Villanelle, but Eve doesn’t answer. Konstantin predicts that Eve won’t survive this mission.
Villanelle, meanwhile, is singing in church and helping clean up after services. A new friend named May marvels: “I don’t know how you can be so good all the time.” Villanelle tells her, “I don’t have any other choice.”
Eve has an elaborate conspiracy board set up with Konstantin, Helene, Dasha and more on it. She’s having sex with a man name Yusuf who she’s doing surveillance work with. Eve gets an invite to Villanelle’s baptism but tears it up.
It turns out that Carolyn was fired from MI6. Hugo is also now on the agency’s Russia desk.
Villanelle has seemingly adopted a godly lifestyle, going by “Nelle” now and living with a minister and his daughter May. One day, she picks up the family cat, and when it hisses at her, she throws it against the wall, killing it. She retreats to May’s bedroom, where she asks the girl to stroke her hair and tell her why she likes her so much. The next day, the minister leads Villanelle through her baptism rehearsal, and she’s saving a seat for “her guest.” He starts to doubt her faith, though, when he sees video of her burying their dead cat. When he asks her if she believes in God, she says she thinks it’s good for her to be around people who believe in God. She knows that people think she’s evil but she wants to prove them wrong.
While Eve is out for a run, she’s greeted by Carolyn, who informs her that members of The Twelve are being systematically murdered. She wants Eve to take over the investigation, but Eve insists she doesn’t want to play chess anymore. She takes the file and heads to a funeral home to check on the dead body of Helene’s last known contact. She presses the embalmer for more information, and the worker shrugs her off — but something about the worker makes Eve’s Spidey senses tingle. And at Villanelle’s baptism, she looks crestfallen when she sees the seat she reserved for Eve is empty and rushes the minister through the ceremony. “Dunk me!” she demands, before plunging her own head into the baptismal water.
Eve heads down to her hotel lobby and gazes at the fish tank there and sees Villanelle on the other side, still in her baptismal gown. Villanelle forgives her for not coming, and when Eve tries to walk away, Villanelle frantically tries to show her she’s changed, dropping to her knees and praying for Eve. “If you really changed, you wouldn’t have come here,” Eve snaps. The two stand toe to toe and Eve slaps Villanelle across the face, firmly telling her, “Different person,” before walking away for good.
Eve tracks down that funeral worker and stalks her until the worker turns around and beats Eve up — but Eve does spot her getting into a fancy car with Helene. Carolyn spits at a government building and then heads to Moscow to slip classified intel to the enemy. And Villanelle is back in church chastising Jesus when she’s joined by May. The girl comforts Villanelle with words, and then a kiss. But Villanelle declares, “You don’t need me” and plunges the poor girl’s head into the baptismal water, almost drowning her before snapping out of it and giving the girl CPR to bring her back.
That night, Villanelle gets the sign she was looking for: a visit from Jesus Christ himself, who says he’s here to lead her into salvation.
