Countdown (FlashForward)

Mark (Joseph Fiennes) continues his questioning of Lucas Hellinger (Neil Jackson) in an attempt to find out when the next flashforward will occur.

All Lucas tells him is that he will die at the end of the day, also stating that his daughter (Lennon Wynn) will be better off if that happens.

Demetri (John Cho) must decide whether or not to turn Simon (Dominic Monaghan) in after finding him and Janis (Christine Woods) on their way to NLAP.

Lloyd (Jack Davenport) solves the complex equation he was working on in his flashforward with the help of his son (Ryan Wynott).

Tracy (Genevieve Cortese) fights for her life, and Aaron (Brían F. O'Byrne) finds out why Jericho is after her.

Nicole (Peyton List) wonders if she should tell Bryce (Zachary Knighton) where Keiko (Yūko Takeuchi) is.

The finale was originally set to be two hours long, consisting of both this episode and "Future Shock".
