See a sneak peek for tomorrow’s Fringe episode “Through the Looking Glass and What Walter Found There,” as well as some new promos and images!

Fringe is about to get trippy, as the team enters a mysterious, time-looping house in tomorrow night’s episode with the extra long title, “Through the Looking Glass and What Walter Found There.”

See a sneak peek from the episode featuring Peter and Olivia:

In the clip, Peter watches Etta’s holographic report over and over again, and hears an intrusion only to see Olivia, who has come to find him. When Olivia sees the Etta hologram, he explains that, “I just needed to see her.” Olivia understands, and asks him to play it again.

The set of promotional images have also been released by Fox, uploaded to SpoilerTV:

We see the team enter the mysterious house, as well as an example of the weirdness going on: there’s a chair on the ceiling! Hopefully we’ll get some light Walter moments to balance out the sadness which will still be lingering this week after the horrific loss of Etta.

Finally, a few new general promos for Fringe‘s final season have been released by Fox, styled like Observer propaganda videos, entitled “Truth Church Protocol” and “Reward Wire Protocol”:

Fringe 5×06 “Through the Looking Glass and What Walter Found There” airs Friday at 9/8c on Fox.
