3 Fringe sneak peek clips reveal Walter's grudge and amber gypsies

Before airing Fringe's fifth and final premiere, Fox has released more promotional clips. They include an irritated Walter and a group of renegades called the amber gypsies. Unfortunately, they're not the only harsh reality the team encounters.

The episode is called "Transilience Thought Unifier Model-11." The group has been thrust into a world ruled by the Observers, and Olivia's nowhere to be found. Not only that, but Walter is expressing some serious anger toward Peter. At one point, Astrid has to step in after one of Walter's snappy comments.

Meanwhile, Etta shows them the lay of the land, including giant carbon monoxide pumps. She reveals, "There's one on every continent. The air here, it's too oxygen-rich for them." That definitely sounds like something they can use to their advantage.

In the final clip, they stumble across several blocks of broken amber. But the bodies weren't taken by the Observers. It was the amber gypsies.

Fringe returns Sept. 28 at 9 p.m. ET/PT on Fox.
