Plot
Clark (Hamish Linklater) questions Lenny (Aubrey Plaza), who denies being controlled by Farouk (Navid Negahban) and wants to talk with David (Dan Stevens), as Farouk knows the location of his body. Somewhere, Farouk, possessing Oliver (Jemaine Clement), locates his body, which is revealed to be a woman's body, from which he takes a tissue sample.

Ptonomy (Jeremie Harris) attempts to read Lenny's mind, but finds that her memories have been disrupted, and sees a vision Admiral Fukyama. David decides to enter her mind, where he discovers that Farouk sent her. He blocks Farouk's influence over her, from which she states that she is unsure on how she could have a new body after she died, claiming that the new body belonged to someone else. Somewhere, Amy (Katie Aselton) tells her husband that she had a dream where she had a mustache while serving a man with a basket over his head, referring to the Vermillion. She is then visited by Oliver, who claims will take her to David.

David then tells Lenny where they buried her body: the desert. Lenny then realizes that Farouk didn't find his body in the desert, he found hers. Farouk, in Oliver's body, located Amy in her hidden location by Division 3. He then killed her in order to infuse her body with Lenny's DNA, which caused the body to materialize as Lenny's. Lenny was returned to the desert, where after waking up, was sent by a horse to Division 3. A devastated David then cries in the arms of Lenny, saying that he is coming for Farouk.

In the episode, the Narrator (Jon Hamm) explores the concept of pareidolia, from which humans can perceive their surroundings as different implications. It is through the perception and pattern recognition that a person could identify either an optimistic or pessimistic view, as well as a person viewing coincidences as "conspiracy".

This was Hawley's eighth writing credit, Halpern's seventh writing credit, and Mielants' third directing credit.

Critical reviews
"Chapter 13" received mostly positive reviews from critics. The review aggregator website Rotten Tomatoes reported a 100% approval rating with an average rating of 7.2/10 for the episode, based on 9 reviews.

Alex McLevy of The A.V. Club gave the episode a "B+" grade and wrote, "The idea that our world is defined by what's missing as much as what's there helps illuminate Legion's theme of loss dictating identity."

Alan Sepinwall of Uproxx wrote, "'Chapter 13' as a whole really pushed the limits of how much the series' remarkable technical design can compensate for weaknesses in other storytelling areas." Evan Lewis of Entertainment Weekly wrote, "Another moderately-paced episode, 'Chapter 13' eschews last week's character development angle to instead build up to a thriller-esque reveal."

Oliver Sava of Vulture gave the episode a 3 star rating out of 5 and wrote, "There are scenes in this episode that have me second-guessing the reality of this season, and when everything is so unstable and malleable, it's hard to know what reality even means within the loose confines of this universe." Nick Harley of Den of Geek gave the episode a 4 star rating out of 5 and wrote, "There’s plenty left in this episode to scratch your head at, like the fact that ol'basket head may be a giant chicken creature (?) or that Oliver plans on bringing down the Shadow King with something as simple as '1 +1.' The creature in Ptonomy's ear appears to finally start doing some damage too. Regardless, when you strip away all of the signature Legion-oddness, you're left with an episode absolutely anchored by a knockout Aubrey Plaza performance, and that's worth watching in any context."
