Netflix’s ‘Allen’ Ending Explained: Why Petey Chooses to Let His Alien Friend Go

‘Allen’ premiered on Netflix on November 12 as the first feature film from Ludo Studio, the company best known for ‘Bluey’. The official logline says that twenty years after meeting an alien, Petey never moved on, and his old friend has returned for a reason that is complicated and unexpected.

That setup leads to a finale that reframes the entire reunion, and the ‘Allen’ ending has already started conversations among viewers. The conclusion is a cliffhanger that hints the alien could return to Earth after unintentionally upending his friend’s life. Here is what actually happens and what it says about Petey.

Allen Ending Explained Step by Step

Petey and Allen shared a spit pact as children, and that handshake left a circle on both of their palms before Allen’s spaceship beamed him away. When Allen returns as an adult, the pair realize Petey has been put in a world threatening predicament.

Allen eventually admits the truth to Petey, who refuses to believe it at first, and even compares the situation to an alien invasion by pointing to ‘Predator’, a film they watched as kids. Communicating with an Etch A Sketch, Allen reveals that the handshake was a reproductive ritual that turned Petey into a living incubator.

Sarah cuffs Rory to a handrail and escapes with Petey and Allen, which sets up the final decision. The chase gives the story its urgency, yet the real drama is the conversation that follows.

Why Allen Returns to Earth

The film begins twenty years after a typical alien friend story would have ended, and the reason for the return is the detail the marketing held back. The answer turns a nostalgic reunion into something closer to a reckoning for both characters.

The film does not spell out its in universe logic, but one reading is that the rings on the palms kept Petey and Allen connected across the universe, and that link fueled the growth of the parasites. Allen recognizes that the bond stems from their shared palm markings and decides to sever the cosmic link.

That makes Allen less a visitor with a plan and more a friend trying to repair a mistake. The ending gives the alien a chance to fix the error that placed Petey in life threatening danger.

Petey’s Choice to Stay on Earth

Allen presents Petey with two options, which are to leave in the spaceship or to die. Although Allen warmly invites him along, Petey chooses to embrace earthly maturity and says a bittersweet goodbye.

Petey tells Allen that sometimes loving someone means letting them go, and Allen accepts the solution and saves him. A one year time jump then shows Petey doing much better now that he is no longer fixated on Allen.

This fits the themes the creators describe. Director Daley Pearson told The Northwest Star that happy endings in films like this tend to say the hero has it all figured out, and he asked “what if you didn’t?” The film explores the lasting impact of childhood loss, with Petey forced to confront grief he has carried for years.

Will Allen Come Back After the Final Scene

The film closes with hopeful ambiguity as Allen leaves Earth while a radio in Petey’s house buzzes, suggesting something extraterrestrial may be on its way. One reading holds that the tease should not be taken too literally, which leaves room for Allen to keep checking in on future generations of Petey’s family.

Some critics see the ending as bittersweet rather than sad, since Petey learns a great deal along the way. Not every reviewer is convinced by the film as a whole. One review calls it dull and says the toll of Petey’s obsession on his family and friends only surfaces near the end, in a sweet but belated reconciliation scene.

Even so, the final image suggests Petey is moving forward on his own terms. The ending shows him finally living his own life. Do you read that last radio buzz as a promise that Allen will visit again, or as Petey’s cue to stop waiting for him?
