Re: Fringe 4x21 - "Brave New World, Part 1" (Live Commentary, Spoiler
What an episode this was!
First of all: I LOVED the reference to 1.19 'The Road Not Taken' with the case of spontaneous human combustion. A great reference to a great episode.
Secondly: The character moments between Peter and Olivia in this were great and I really liked how talking to Jessica raised questions for Olivia about raising a family with her lifestyle.
Thirdly: BELL IS BACK!

It's definitely a plus to see Nimoy return to the Fringe world, even if it's a bit of a Mr.Hyde version of Bell.
Fourth: Walter. That character is priceless. There were so many wonderful Walter moments in this episode, and I loved the Easy Back Oven with the regenerating lemon cake. Of course, only Walter would add pig brains to it.
Finally: The ending. WOW. I loved that Astrid broke out into some karate skills there and was defending Walter. Go Astrid!
My reaction to her being shot, however ->



I really hope Astro makes it through! People have already mentioned that because of the future timeline we saw, Astrid has to survive, but this is Fringe we're talking about here. We saw a future timeline at the end of season 3 and it did not come to pass, so who's to say that the one we say in 'Letters of Transit' will?
In addition to Astrid's kung-fu skills, Olivia revealed some new skills of her own. That was some wild teleskinesis she was wielding there. She actually took control of Peter's body and kicked Jones's ass! That's another thing, the twist with Jones being the Bishop was great; I thought it was Peter for sure!
I rated this episode excellent for the above reasons as well in addition to the concept of using the Sun to literally try and set Boston aflame, as well as the sneaky use of the 'X' on the nanites (I loved the use of nanotech in this!

) that Mr. X had on his shirt in "Lysergic Acid Diethylamide'.
So now the question is: If these nanites were desgined by Bell, and Mr.X was someone from Bell's mind, could this Mr.X be Bell himself? From next week's promo, someone close to Peter is clearly shot, which means that it is either Walter or Olivia. Walter has survived a gunshot before and I believe Olivia has as well. But will they survive this time?
