List of Heroes episodes

"The Butterfly Effect" is the second episode of the third season of the NBC science fiction drama series Heroes and thirty-sixth episode overall. It was written by series creator/executive producer Tim Kring and directed by Greg Beeman. The episode aired on September 22, 2008 immediately after "The Second Coming" as part of the three-hour premiere event.

Claire Bennet realizes that she no longer feels pain when injured. Claire films herself trying to be hit by a train, but Future Peter, masquerading as Present Peter, intervenes before the impact. After exchanging words with Claire, he then teleports away.

Meanwhile, two Company agents, Bianca Karina and Gael Cruz, attempt to capture Sylar. He kills them both with a small hand gesture.

Tracy enters Nathan's hospital room to offer him a seat on the Senate. Nathan believes that Tracy is Niki Sanders, but she insists that she is not. Tracy leaves, somewhat disturbed, and Linderman appears, confirming that Tracy is not Niki.

At the Company, Elle Bishop finds her father, Bob's body with his brain removed. She then lets Noah out of his cell on Level 5, giving him a gun and telling him that Sylar is in the building. Elle is telekinetically thrown down the hall by Sylar, so Noah shoots him several times. However, Sylar regenerates and explains that he's already taken Claire's power. He attempts to take Elle's power by cutting her head open. Elle screams and releases a large electrical discharge that knocks Sylar out and allows the Level 5 prisoners to escape their cells.

Future Peter explains to Nathan that he is actually from the future and came to the present to stop him from revealing their powers. Nathan proceeds to call Tracy and accept her offer as Future Peter leaves.

Tracy, walking to her car in the parking garage, is confronted by a reporter, (cameo by "Hero" William Katt), who uses a video feed of Nathan and Jessica Sanders (from season 1) to try to blackmail her to get her to admit she is Niki, a stripper from Las Vegas. An angry Tracy grabs him, and her emotions trigger her ability of cryokinesis. She accidentally freezes him solid, and he shatters on the ground, dead. Tracy flees the scene.
