Fringe "peter"

Last nights episode was fantastic! I loved the retro intro! LMAO at Nina's mobile phone! and "Is this Russian technology?" We all knew the major events but it was still cool to see how the minor details weren't overlooked such as Nina's hand. The scene where Walter and his assistant have a confrontation in the lab was so powerful...I felt the darkside over coming Walter! Fantastic acting!!!!I'm guessing the blonde assistant is the one that dies in the "lab accident", the episode where Peter tries to protect Walter from her daughter. One thing I noticed is it appears the observers can cross between universes with out any technology.
Fox has an A+ show and it seems they know it, fantastic start to a new season!
