Walter takes the news particularly hard and makes his way to the chapel. In Season 2’s episode ‘White Tulip’ Walter bonds with a fellow scientist who is also on a mission to save a loved one that has died in the past. He reveals to the MIT professor that he believes God is punishing him for his actions and that maybe with time; God would forgive him for disturbing the balance between both worlds. John Noble was so incredibly moving and powerful in his conversation with God. Walter admits he found solace in believing that God had forgiven him. “I’ve changed. That should matter!” He was willing to let Peter die when he couldn’t do so before. On his knees, he prays to God to punish him, not Peter and to spare our world. This emotionally driven scene was the highlight of the episode. Walter’s evolution as a man, a scientist, and most importantly, a father has not only profoundly enriched his character, but will eventually give Walter the strength and determination needed to redeem himself for what he has caused.
Meanwhile, Olivia desperately searches for the increasingly mysterious Sam Weiss, who has gone missing since the activation of the machine. Weiss is shown doing several observations. When we first see Weiss, he takes out a Newton’s Cradle and places it on a desk. He watches the iconic device and eventually the metal balls start moving on their own. Perhaps there is another unseen force present?
Could it be there was a significant change in energy to cause the cradle to be set in motion? The next time we see Weiss he is continuing his observance on the effects of the machine, while solving a mathematical equation. If you watch closely, his equation equals zero. The look on his face suggests that there is something seriously wrong with the way events are unfolding.
Olivia is distracted from her hunt for Weiss, when she hears the news about Peter. As she sits and processes what she has just learnt at the hospital, she observes the shadows on the ground. She walks outside to see the sunrise, her favorite time of day, when the world is full of potential. At the moment, Sam Weiss appears and tells her to trust him because they don’t have much time. Desperate for answers, she follows him as Weiss takes her to the machine.
On the other side, Altlivia learns of Walternate’s plans to destroy the other universe. The information doesn’t sit well with her, as this would mean the annihilation of people from the other side, not to mention that the father of her child is over there as well. In a bold attempt to bring Peter back, she tries to cross universes with the device stolen from Alt-Brandon. Her attempt fails, resulting in her lockup in the same cell that Olivia was once in.
