Recap Alien: Earth (2025): S1E06 – “The Fly”
The latest episode of Alien: Earth opens with Boy Kavalier (Samuel Blenkin) creepily reading from Peter Pan again. Kirsh (Timothy Olyphant) and Joseph “Joe” Hermit (Alex Lawther) observe Wendy (Sydney Chandler) and a teenage alien talking. Joe asks the synth about hybrid maintenance, and Kirsh realizes that he has plans for his sister. He tries to impress upon the man that his sister isn’t going anywhere, but they agree to disagree.
Meanwhile, Nibs (Lily Newmark) is lying in charging mode while Dame (Essie Davis), her husband Arthur Sylvia (David Rysdahl), and Atom Eins (Adrian Edmondson) look on. The hybrid had a meltdown in the last episode due to the PTSD of the crashed ship, and thought she was somehow pregnant. They say whatever’s wrong isn’t a hardware problem. Boy Kavalier’s right-hand man orders them to “fix her” by erasing Nibs’ memory. He also wants her personality to be calmer, but when Arthur refuses, Atom immediately fires him. There’s been tension between the couple for a while, but this betrayal may have been the last straw.
Later, Joe confides in Wendy that he believes the decision to bring the aliens here was a mistake. Joe doesn’t like that she feels sorry for the aliens and tries to convince her that they’re killing machines. She compares them to bees and ants and feels this xenomorph is good. She wants to embrace opportunities and explore them with Boy Kavalier. He tells her she’s working on getting them out, and she asks, “What if I don’t want to go?” Joe still sees her as his little sister, but she’s becoming something much more.
Shoeless Joe shows up late for a meeting with Yutani (Sandra Yi Sencindiver), Kumi Morrow (Babou Ceesay), and McAfee, an appointed moderator. The young trillionaire places his bare feet on the table in a clear display of arrogance, especially since the Japanese consider being barefoot to be ill-mannered. Boy Kavalier cuts Yutani off as she tries to be serious and states that she wants Weyland-Yutani’s property returned. He says the ship and everything on board are being kept because thousands of people in “his” city were killed. Boy Kavalier accuses Yutani of a cover-up, but Yutani desperately offers $20 billion to retrieve her cargo. He agrees but says the creatures inside must undergo a six-week quarantine “for the good of the planet.” This will allow the Prodigy team to work on the captured aliens and whatever evil plans he has for them. Yutani, angered by her humiliation, listens to Morrow’s plans to “destabilize” the facility and steal the specimens. It’s clear he’s in charge now.
Later, Kirsh catches Morrow in the elevator, and the two have a passive-aggressive conversation about whether robots or cyborgs are superior. Both are being made obsolete by the hybrid program.
Back in the lab, Nibs is brought back online by Dame Silvia after she has erased the horror from her memory. The redhead is confused when Wendy visits her pal and starts asking questions about a crashed ship. She doesn’t remember a crash or anything. Nibs’s fear returns as she worries about why she has missing memories. Morrow is still bothering Slightly (Adarsh Gourav) about sacrificing a human to the facehugger, so she is not the only Lost Boy having difficulties. He and Smee have a heartwarming “best friend” moment. Later, Slightly visits Joe with the intention of bringing him to the lab for the facehugger to assault him. But Joe is taken on patrol before he can lead him to the lab. Joe continues to inquire about leaving the island while on the grounds with the other Prodigy troops, but Siberian cautions him to halt his plans.
Back with Wendy, she’s becoming more engrossed as she chats to the nearly mature xenomorph. In the lab, Kitsch asks Isaac (aka Tootles) to look after the specimens and get one ready for the next experiment. The boy dutifully gets to work, but accidentally tears off one of the security doors. So he unlocks the cage to feed the alien flies. The Trypanohyncha Ocellus (or T. Ocellus) living in Victoria, the sheep sees its chance and startles him by banging its head against the window. This traps him inside with the bugs. They spit acid on him and eat his synthetic skin. Turns out the hybrids aren’t safe from the aliens after all. The sheep goes to eat the grass he left, and the disturbing scene ends.
Dame Silvia is confronted by Wendy over Nibs’ erased memory. The fact that Nibs had no control over what occurred to her upsets her. Dame shifts the conversation to Wendy’s extensive use of the secure laboratory. The hybrid is angry that the aliens are being used for experiments like The Lost Boys. She believes that they are identical, and if disassembling things is what humans do, she doesn’t even want to be regarded as a person anymore. Kirsh told Marcy (that’s how she wants to be called now) that although the hybrids are unable to feel, they can see the world as it really is. Does she want this? Because she wants to help her, Dame advises Wendy not to listen to a robot, but Wendy questions whether people are the real problem in this world.
While Arthur is packing up his stuff to leave, Wendy’s brother comes in. Hermit wants to know if Wendy is safe on the island. He wants an honest response because he knows how much the scientist cares. After glancing at a camera, the former Prodigy employee insists Wendy is safe. However, he pretends to show Joe the hybrid vitals on a computer screen and writes “Take her and get her out,” followed by a code for the boat.
Arthur then shuts down the hybrids’ trackers and turns off the monitors. After Joe leaves, the scientist sees an alert on screen about Isaac in the secure lab. He’s going to wish he never investigated, especially with a nervous Slightly sitting outside the door when he gets there. All the while, Kirsh calmly watches everything that’s about to play out remotely from his screen.
When he goes to check on Tootles, Slightly opens the cage with the eggs and locks him inside. In a truly horrifying scene, the facehugger captures him. As the hybrid drags Arthur into an air duct, a fly escapes and barely misses making them his next meal. But the cliffhanger is that all the specimens are now on the lose.
