'Fringe' Final Season Promo Previews Walter Bishop In Trouble (VIDEO)

We're still mentally preparing ourselves for the final season of "Fringe" (premiering Fri., Sept. 28 at 9 p.m. ET on Fox), and intense teasers like the one below aren't calming our nerves much.

In the latest promo for Season 5, we see further evidence of The Observers' invasion of Earth, with the follicle-challenged time travelers not only ruining Peter (Joshua Jackson) and Olivia's (Anna Torv) idyllic picnic with their daughter, Etta, but also capturing and torturing Walter (John Noble). This means war!

Watch the new trailer below and share your thoughts in the comments.
