(S02E03) "Get my portable chemistry set ... this means bodies!" - Walter to Astrid

This episode of Fringe sort of went along without too many shocker moments -- until the last few minutes, that is. I wasn't all that surprised about the serum that turned people into human explosives, or even that it might be part of a top-secret military experiment. But I was wondering when our friend The Observer would turn up again in a big way and dump something spicy all over his plate of food.

(S02E02) "We're all victims of our own gene pool. Someone must have peed in yours." - Walter to Sheriff Golightly

Creature feature? Or relevant to the alternate universe storyline? Those were the questions running through my head as I watched this episode of Fringe.

What I believe -- at the moment -- is that all of the creature features we had during season one are somehow relevant to the overall storyline. Since things are slightly different in the alternate universe, perhaps there are creatures there who've evolved or avoided extinction that have somehow made their way back to this universe. Of course, it appears that this episode's creature was created right here.

In anticipation of the season two premiere of Fringe last week (read my review and your comments here), I revisited season one to refresh my brain. There are so many subtleties that connect seasons one and two, and it was good to go back and watch it again.

While there were a few creature-feature episodes that appeared to be stand-alones (but who really knows with this show?), for the most part, much of season one was devoted to weaving an intricate mystery and setting things up for season two. It's too much, really, for one small blog post, but a few things sprang to mind ...

(S02E01) "I went somewhere." - Olivia to Peter

I can hardly contain my giddiness that Fringe is back, so ... yay! ... Fringe is back! More mystery! More intrigue! More Walter Bishop! More Jean! More jump-out-of-your-seat moments!

It's been a long summer since we last left the crew with Olivia in another dimension, Walter visiting Peter's grave, and the mysterious William Bell played by the mysterious Leonard Nimoy. Follow me after the jump to explore how the season is shaping up so far ...

Fox has released a few photos from the Fringe season two premiere, "A New Day in the Old Town," which airs Thursday, Sept. 17, at 9 PM ET. I'm so ready for the return of Fringe, and anxious to see where the show goes this season with the parallel universe storyline. And I've really been missing my Walter fix since season one ended earlier this year.

Interesting that there's no sign of Anna Torv in the photos. Rather, junior agent Amy Jessup (Meghan Markle) is pictured in the last photo after the jump. She's been assigned to an investigation with the Fringe Division. That would be Walter Bishop, Peter Bishop, Astrid Farnsworth and, supposedly, Olivia Dunham. Maybe she got stuck in the alternate universe. Walter apparently made it back!
