This week's episode was all about Peter. Most of the episode takes place in 1985 when Walter was working on a cure to save his dying son. Using a portal he created to look into the alternate universe, he spied on “Walternate,” the copy of himself on the other side. Ultimately, Peter dies in this universe. Walter then, having perfected the cure for the disease, travels over to the alternate universe, to save Peter’s copy from dying.
Many interesting plot points were disclosed in this episode, such as, what happened to Nina Sharp’s arm and her ambiguous relationship with Walter, the true origins of “The Observers” place in the story, Carla Warren the lab assistant who died in the fire, and the way Walter’s actions changed the course of time.
By bringing over Peter’s copy from the alternate universe, Walter started the first crack in a pattern of cracks in our reality. He is the sole reason why the Pattern is even happening. The few scenes in real time dealt with Walter spilling his guts to Olivia in an attempt to have her understand his reasons for doing what he did.
I dug all the retro 1985 details the director added to the show, especially changing the open credit sequence. John Noble, the actor who plays Walter Bishop, is one of the best actors in television. His dramatic range and uncanny ability to play the idiosyncratic Bishop truly deserve some award recognition.
All things considered, a wonderful return to primetime for a creepy, smart, fun, and utterly mind-bending show that continues to push boundaries.
