'FlashForward': Preview of Episode 21 'Countdown'
Changing a vision of the future seemed impossible at first, but now it looks like it's the trend. On FlashForward tonight, our characters realize that their fates are far too complicated to tamper with. But they still try to.

Check Out What Happened Last Week on "The Negotiation"

The possibility of Mark Benford's (Joseph Fiennes) death lies on the penultimate episode of FlashForward, "Countdown." The dreaded day is nearing and millions worry, but it's this agent who has to fight for his life.

Still, he keeps working on the investigation. Desperate to avoid another global blackout, Mark questions Lucas Hellinger (Neil Jackson). Unfortunately, this suspect isn't giving out any information, except for the fact that Mark is going to die. With the show being canceled already, he might as well.

Tracy (Genevieve Cortese) is also fighting for her survival, especially with that elite and notorious Jericho after her. But her father might have something up his sleeve. Aaron (Brian F. O'Byrne) is finally aware of why the organization is hunting down his daughter.

Also on "Countdown," Demetri (John Cho) struggles with the decision of turning Simon (Dominic Monaghan) to the authorities. He's been valuable in the research, but is simply too difficult to trust. Sounds a bit like Janis (Christine Woods), doesn't it?

Speaking of her, the double agent will also find herself in the middle of a couple's quarrel. Demetri has a big revelation to Zoey (Gabrielle Union), which might make her want to wish him dead anyway.

Another tough choice is in the hands of Nicole (Peyton List). She found Keiko's whereabouts, and is holding back on telling Bryce (Zachary Knighton) about it.

Meanwhile, Lloyd (Jack Davenport) stumbles upon the answer to the complex equation that he saw in his flashforward. Is that why he's starting to approach Olivia (Sonya Walger) once again?

But one of tonight's most dramatic scenes is bound to come from Charlie (Lennon Wynn). Find out what on the clip below.

Check Out Photos From the Series Finale

It's one major series of events leading up to the finale, and it would be great if FlashForward would continue. But ABC has axed it at last, so let's just savor the show's concluding moments. Don't forget to catch "Countdown" as it airs tonight at 8pm.
