Yeah this episode was Sick! What an great way to end the premier season. I can't wait until Fall!

I'm not sure about any of you, but I'm seeing a LOT of similarities between this show and Stephen King's The Dark Tower... a LOT of similarities!!! Do any of you think they could connect the two? JJ is a huge fan of King and King is a huge fan of JJ. Actually King has given only JJ his blessing to do any kind of adaptation of The Dark Tower. From what I've heard he's the only person he's even considered for it. There is just so much potential with this show it's scary!

Stop giving the JJ credit for Lost, Carlton Cuse & Damon Lindelof have been running that ship for a long time.

Cool ending for the season, I would've preferred they wouldn't have gone with Nimoy for William Bell.  They shortned the character arc cause Nimoy would only do so many eps.

 I said it before and I`ll say it again. Fringe is a damn good show. It hits all the right marks and is a great successor to the X-Files.
 That scene at the end with Walter at the grave was just sick. I sort of had the feeling that it was something like that, but you never can tell with Walter. It does explain alot from previous episodes. I always assumed that Peter called Walter by his first name out of kind of anger at him for going nuts, but its obviously more than that. I wonder if Peter will ever find out, because there are so many secrets that Walter is keeping from him and Olivia.
  And then the end scene in the office was just freaking nuts. Its funny because when Olivia went to the window I thought the window structure looked familiar. And I wonder what happened to the White House, that Obama had to move into a new one.
   Awesome finale!! Anyway, I can't wait until next season!

My guess would be 9/11 happened on The White House instead of WTC.

I didn't even catch that headline. On 9/11 the plane that crashed in the field in PA would have crashed into the White House if the people on board didn't fight the terrorists. That's the fork in the road where you either do one or the other, both have different consequesnces. This whole show gets deep! That's awesome when they put it visually like that!!!

Yeah, I started piecing together where Peter was really from a couple of episodes ago when they started ramping up the memories of Walter and Peter's early life not quite meshing together. One would remember something happening that the other wouldn't.

I'm wondering if Bell is in the alternate reality to stop the Walter of that reality. Mainly because I think our Walter was the one who wrote the manifesto in the first place, and is the leader of ZFT but just doesn't remember it.

Did anybody else watch the now-canceled US version of Life on Mars?

I thought it was interesting that Life on Mars began with Sam waking up in 1973 to the mind-blowing vision of the Twin Towers standing in the NYC skyline. Now the season ends with Fringe using the WTC in a parallel universe. It's become a rather powerful visual way of saying "we're not in Kansas anymore."

BTW, the fourth hijacked plane was not intended for the White House, but for the US Capitol building. 9/11 organizer Khalid Sheikh Mohammed revealed this in an interview with al Jazeera a few years ago. It actually makes more sense - the Capitol is not only technically the seat of government, but it's a much more massive building than the White House, and sits exposed on a hilltop making it an easier target to hit.

Holy hell that was a double threat of shocking twists. Fringe nailed a perfect 10 on that landing. Kudos!

I think the only thing cooler than Nimoy being William Bell would have been if Bell were the "other" Dr. Bishop, who is not so crazy, or crazy like a fox!

Remember, there are 2 of everything.

For me, the Twin Towers scene was a gut twister. It was different with Life on Mars because that was the past. But in Fringe, the thought that there could be a scenario where it didn't happen - it makes me so sad thinking about what we've lost and what could have been.

I agree with Stephen that this episode probably lost anyone who tried to tune in for the first time. For those of us who've watched it all along, it was perfect. But it relied heavily on things that had gone before.
