The two men briefly and tentatively reconcile. They jointly travel back in time, experiencing and reshaping an event where Abe's girlfriend Rachel was nearly killed by a gun-wielding party crasher. After many repetitions, Aaron, forearmed with knowledge of the party's events, stops the gunman, becoming a local hero. Abe and Aaron ultimately part ways; Aaron considers a new life in foreign countries where he can tamper more broadly for personal gain, while Abe states his intent to remain in town and dissuade/sabotage the original "box" experiment. Abe warns Aaron to leave and never return.
