I Know What You Did Last Summer: Ending Explained

Who is The Killer in “I Know What You Did Last Summer”?

Dylan and Alison discover Helen murdered in Clara’s old house. Dylan calls 911 but is attacked and knocked unconscious. Margot sits crying in a corner. When Alison tries to help her, Margot confesses to killing Helen. Margot admits she knows Alison has been posing as Lennon since the summer. To get Alison to accept her lie, Margot murdered everyone she cared about. Margot stopped killing when she fell in love with Alison. But that Alison slept with Dylan made Margot angry. She offers Alison one last chance to tell the truth, but when Alison insists on being Lennon, Margot stabs her.

When Lyla hears about Dylan’s 911 call, she rushes to Clara’s house. Dylan comes to and tries to stop Margot from stabbing Alison. When Margot confesses to leaving Dylan’s DNA on the blade of the knife, he realizes she was planning this all along. Dylan snatches the pistol from Margot when Lyla steps in and arrests the two teenagers. When Alison claims that Dylan attacked her, he is arrested. This is how Alison returns Margot’s affection for her. The episode ends with Alison spending time with Margot after she recovered from her injuries a few weeks later.

In the end, Alison takes Margot’s side, despite her unstable mental state and murderous drive. Alison’s decision could have been influenced by one of two factors. First of all, Margot is aware of her identity and, unlike Dylan, can prove who she really is. Hence, Alison’s decision to protect Margot is reasonable. Margot, however, admits that she doesn’t care what Alison’s first name is as long as she loves her.

Bruce also exchanged photos of Alison and Lennon. Wade concludes that Alison is the late twin, thus protecting her cover. Bruce also exchanged photos of Alison and Lennon. Wade concludes that Alison is the late twin, thus protecting her cover. So that Alison should take Margot’s side to keep her secret is illogical. The second possibility is that Alison really loves Margot. Margot has been there for her since Lennon died. So by saving Margot, Alison shows Margot that she really loves her. Alison also lies to Bruce about Helen’s death, thereby proving her love for Margot and her willingness to protect her.

What Happens To Dylan In The End?

Dylan has acted strangely in the previous episodes. Margot keeps telling Alison that Dylan is the killer. In the end, Dylan is just a troubled youth falsely accused of a crime. As soon as Dylan meets Clara’s sect in the cave, he becomes obsessed. Like Clara, he begins dissecting animal brains and feeding them to spiders. Dylan’s actions make it easy for Margot to be framed, and with the help of Alison’s testimony, he is arrested. The spiders and Riley’s hand are also discovered by the police in Dylan’s house. Dylan’s fate is sealed and he is sent to jail.

Most of all, Margot despises Dylan. In hindsight, she doesn’t like Dylan because he’s competing for Alison’s affection. So she kills two birds with one stone by framing Dylan with the murders. Margot is not only acquitted of her crimes, but also by her romantic rival. After reading Clara’s cult Bible to fellow inmates, Dylan appears to be considering continuing Clara’s mission if he is released.

Is Riley Still Alive?

In the last few seconds of the episode, we see Riley’s body, embalmed in honey, in a forensic laboratory. At the last moment, Riley opens her eyes. Riley appears to be alive! But it is uncertain whether she is herself or has changed.
