Hiro arrives at the diner only to find Sylar preparing to kill Charlie. Back at the carnival Samuel assesses that Hiro is needed in order to replace the sick time traveller Arnold. He sends Arnold back in time to stop Hiro from saving Charlie. Meeting up with Arnold, Hiro promises to maintain the equilibrium after saving his love. Hiro saves Charlie but realises in doing this he will never fall in love with her. He meets with Charlie and just as her health declines he convinces Sylar to stop her brain aneurysm. After this Hiro tells Sylar about the man he once was, but Sylar declines any offers of help. Hiro is then fortunate enough to share a kiss with Charlie, but then she disappears. Samuel confronts Hiro and says he has her trapped in time. The only way Hiro will see her again is if he helps right the wrongs of Samuel’s past.
