With CLOE missing from the night before, LEX organizes a search party, but unfortunately they’re headed in the wrong direction. CLOE observes the Locos in there search for ZOOT and later finds herself in danger of bing captured herself. Elsewhere, JACK and DAL continue to work on purifying the recent rainwater and stumble across an ancient breakthrough.
Despite having won the election, LEX appears to be losing his war against AMBER as the boys begin to help the girls with their assignments, and he takes it out on BLUEBELL. Meanwhile, JACK and DAL are hard at work trying to solve the problem of purifying the tribe’s water supply.
Frightened by ghastly sounds coming from beneath the mall, the guys accompany LEX into the sewers to investigate— that is, all but BRAY, who seems to know what the others are after. But the group may have an even bigger problem when a leak in the water tank is discovered.
It’s up to LEX to get JACK off the hook for hiding food from the rest of the tribe— otherwise, LEX’s own secret supply of water may be revealed as well. Meanwhile, displeased with LEX’s sexist work assignments, the girls decide to band together, refusing to work until fairer tasks are assigned.
The tribe holds an election to determine their leader, choosing between AMBER and LEX. Meanwhile, JACK’s secret food stash is revealed after PATSY and PAUL find themselves losing big to RYAN in hands of poker. As a result, JACK himself is on trial for hoarding the food.
Unexpected “guests” have been found in the mall, prompting a new method for assigning chores— now, if only there various tribe members can adhere to their assignments. An admission of love awkwardly puts BRAY between two jealous girls, while another rejects LEX’s advances once more. Meanwhile, the Locos have found a new leader.
Upon learning that he is the father of TRUDY’s baby, ZOOT is strongly encouraged by BRAY to give up his leadership of the Locos. But before her can make his decision, the rest of the tribe is alerted to the secret meeting, and a struggle puts an end to the conversation sooner than expected.
SALENE is fed up with the lack or respect for the chore assignments around the mall. TRUDY is awake and doing much better, but will a reluctant meeting with a mysterious stranger put her over the edge?
TRUDY’s illness has worsened, and BRAY’s persistent disappearances are increasingly aggravating the rest of the group. Meanwhile, LEX has an apparent change of heart when it comes to TRUDY’s well-being, and BRAY’s secret may finally be revealed… or will it?
BRAY still hasn’t returned, and TRUDY continues to be ill, preventing her from feeding the newborn baby and prompting DAL to make the dangerous trek to his father’s surgery at the abandoned hospital for antibiotics. Meanwhile, AMBER takes charge and implements a rationing system for food and water, such to the dismay of LEX and RYAN who bully JACK into doubling their portions.
BRAY and TRUDY have been voted out of the tribe, but it seems TRUDY’s contractions have started, prompting LEX to suspect a con. Throughout the day, while TRUDY’s labor drags on, DAL volunteers to venture into the city to find supplies for the baby, CLOE secretly feeds and plays with the calf, and PASTY and PAUL continue to blackmail JACK for food from is secret store.
BRAY explains that he’s been spying on the tribe to make sure the mall is a safe place to bring TRUDY to have her baby— but should she be allowed to stay? Meanwhile, CLOE finds a new four legged friend that’s been chased through the streets by the locusts, and PATSY and PAUL discover JACK’s secret stash of food.
A mysterious figure watches the group at the mall as AMBER informs DAL that they can’t abandon the others. The group decides to form a new tribe of their own, make their home in the mall and, on sharing supplies and resources, forge a safer future. But what to do with the prisoners? With little choice, AMBER offers LEX, RYAN, and ZANDRA, the opportunity to join the tribe on the group’s terms.
When AMBER and DAL find CLOE wandering the streets, they have her take them to her companions SALENE, PATSY, PAUL, and their dog BOB. Meanwhile, LEX, RYAN, and ZANDRA — laying low after a failed attempt to join The Locusts — decided to pursue AMBER’s newly formed group to the mall, where they all find JACK, it’s self proclaimed owner.
