Watch three minutes of Marvel's Agents of S.H.I.E.L.D. Season 1 finale

Marvel's Agents of S.H.I.E.L.D. airs its Season 1 finale on Tuesday, and executive producers Jeffery Bell and Jeph Loeb have already teased the possibility that not everyone would make it out alive. And now, an extended clip of the episode is available to watch!

Check out the following three minutes from the finale, entitled "Beginning of the End."

The two producers spoke to TV Guide and hinted that not everyone will make it out alive.

"It's a 'who survives?' story and much more," Bell said. "Our show becomes one big landgrab. There are former S.H.I.E.L.D. agents and Hydra cells now scattered out all over the world and no one knows who to trust. That's a very rich, exciting thing to explore as we move forward."

This week's episode focused on the past of Agent Grant Ward, who fans recently learned worked for Hydra. But Loeb teased that all may not be as it seems with Ward:

"He may be a good man who was programmed to be bad or a triple agent secretly working for Coulson all along, or exactly what he seems - an evil son of a bitch. By the end of the season you'll be able to make your own decision on that."

The article also said to expect more information about Skye's true parentage by the end of the season.

TVLine posted some spoilers on the finale, as well:

"The EPs sum up the season ender as 'too big,' to the point that, they joke (?), it's been a struggle to produce. Tancharoen elaborates slightly: 'We'll put some of the things that we've built over the course of this season to bed, as well as tee up mysteries for Season 2.' As for an encore spoiled by a certain Marvel-verse actor, Whedon playfully hedges, 'We don't know anything about that!'"
