Claire Bennet, in an apparent suicide attempt, jumps off an 80-foot platform, caught on tape by Zach. She also mentions that she has stabbed herself in the chest and shoved a steel rod through her neck, all in an attempt to seriously hurt herself or prove her power of regeneration.
Nathan Petrelli tries to explain the fact that he and Peter flew as a failed suicide attempt by Peter. Later, while recovering in the hospital, Peter's mother reveals that her late husband was clinically depressed for years, and that he finally committed suicide after two failed attempts. Much later that night, Nathan watches as Peter threatens to jump off the edge of the roof unless Nathan admits that he flew.
Eden jokes that macaroni and cheese is what Americans eat when they want to commit suicide slowly.
Nathan ignores Peter's insistence that they are "special". He tells Peter that a reporter is investigating Peter's apparent suicide attempt. Later, in a press conference aimed at helping his campaign, Nathan announces that his father committed suicide after a battle with depression, and claims that Peter's fall was also a depression-related suicide attempt.
Confident of her regenerative powers, and intent on teaching Brody Mitchum a lesson, Claire purposely crashes Brody's car into a wall in what would appear to most to be a suicide. (According to Aftermath, Claire was not wearing a seatbelt.)
After Mr. Linderman's prosecution becomes more public, Mr. Petrelli dies. Nathan tells Peter that their father died of a heart attack. (He did not yet know that Mr. Petrelli took his own life on April 25.)
At the Odessa Police Department, Peter tells Claire that this healing power is new to him and that he didn't know he was going to be all right when he jumped off the building with Sylar.
Eden is intent on using her persuasive power to have Sylar kill himself. She brings him a gun and attempts her power, but her plan backfires. When Sylar tells Eden that he will steal her power, she turns the gun on herself and shoots, much to Sylar's chagrin.
To help Zach regain his memory, Claire repeats her original jump from October 1st.
Hiro recalls the stories of Takezo Kensei who plunged a sword into his own heart and handed it to a dragon. He committed this act of seppuku rather than give up the life of a princess. Hiro tells his father that he is willing to cut out his own heart.
