Also, that it was never Walter's intention of taking Peter over to this world instead he brought the cure there to give it to him but something happened and he had no choice but to do what he did.

As MrJaw mentioned, Nina Sharp tripped our Walter and he fell and the container holding the cure broke so he had to bring Peter back. That was a incredible episode. My only question is if the other side was more advanced than our side, why didn't the other Walter try to come over to look for his son.
Now the other big question, at least for me is what drove Walter insane? I always thought crossing over to the other universe did it.
I loved the 80's version of the Fringe theme, complete with synth, cheesy Tron-esque 3d graphics and guitar riffs. So awesome.
So the Razr was invented in thier time in 1985? woah. I love how the Alternate World is a mix of old (Zepplins) and new (digital cell phones). Also when Walter says that his crossing started it all, I don't think he knows how much he means that. I think Walternate, with his son 'kidnapped', created an alternate version of ZFT and is probably the true mastermind behind the attacks on the original Fringe World. What I wanna know is what Belly has anything to do with it?
@mike10: Walter'sunstable state at the start of the series I think is due to an ep earlier in season 2 where it was revealed that pieces of walter's brain were removed and stored elsewhere. We see that once Walter was reconected to him, he displays to more lucid, confident Walter we see in this episode's flashback.
Walter may think that he started it all by crossing over, but my bet is that William Bell was already over on that side. I mean, on vacation, unreachable for Peter's funeral.... unreachable because he wasn't in our universe.
Absolutely amazing episode. Bennyhill, I was thinking the same thing about William Bell. In fact, it seemed to me that Walter hinted at that during his conversation with Nina. When Walter's colleague, the blond scientist, went to Nina, I said out loud "So this is how she loses her hand!" and she did.
Peter falling through the ice and dying (as he would've except for the Watcher) seemed almost like the universe seeking balance; as if Peter being in our world where the "our world Peter" was already dead was an affront almost to the laws that govern such things (the religious claptrap that Walter derided in his conversation with his colleague).
This episode gave me a really strong Twilight Zone vibe, and I mean that in the best possible way. I wonder what revelation we will find out about Peter. The watchers seemed to think he was special, enough to intervene on his behalf.
Well - it was the Watcher's fault for making Walternate miss the cure because Walternate was distracted b him. That Peter was supposed to live not the Peter in our world. So - now Peter is alive like he's supposed to be but he's in the wrong world.
Great episode. Just finished it up. All I have to say is I love having Fringe on the air. It really fills the void that's been hanging around since The X-Files hayday.
Great episode! But you forgot to mention that this episode confirms that the Observers can cross between the two dementions! It was hinted at before, but I don't think it was ever actually shown until this episode!
