Fringe Season 4 Finale “Brave New World Part -2”

Note: This contains Spoilers!

Story:
The fringe division try to find Walter and William Bell and try to stop a catastrophic event concerning the two universes.

Review:
This episode was just awesome! Though the lines were slightly cheesy and the villains kinda cartoonish. Leonard Nemoy, is a great actor, but his role as Bell wasn’t all that impressive this time around. His objective is to destroy the two world and start anew without any Humans. He has some kind of Noah’s Ark with all mutant beings and what not. He even proposed that Olivia and Peter be ‘the new Adam and Eve’. But hasn’t this happened already in other cartoons and superhero movies and TV shows.
But other than the cheesy dialogues and cartoonish villains, the episode was awesome. It has some interesting events. Just when you think that we are going to get a happy ending, guess what? We don’t!
Walter gets an uninvited guest. September tells Walter that they ” have to warm them. The others are coming.” This means that the Observer invasion is coming soon.
And remember last week I said that ‘Brave New World Part-1’ established connections to ‘Letters of Transit’, I was wrong. I thought that the Cortexophan thing done to Olivia is ‘What he [William Bell] did to Olivia’ turns out that in this episode Olivia is probably cured of her Cortexophan powers. So… What did he actually do to her? How is he travelling between the two universes? Why are the Observers coming? Where is Olivia in 2036? Are the questions running through my mind after this season.
But hopefully all of my questions would be answered in the next season.

The fifth and final season of Fringe airs in September.
Fifth season in September with September and the other observers. Coincidence?? I don’t think so.
