Walter visits Olivia. Having a cup of tea together, Walter starts explaining to her how Peter is not really from our world. In the '80s Walter, who was a different man back then, built a device through which he could see the other Universe so, practically, a window to the other Universe. After Peter's death he wanted to do more than just observe; he felt it was his job as a father to do so. Because of September, Walternate couldn't figure out the right compound for the cure to save Peter's life so Walter decided to cross the worlds in order to save the other Peter. This, however, created a wormwhole into the alternate Universe that has had devastating consequences. Written by Andy Ward

Did You Know?


When the movie theatre from the alternate universe is seen, it is showing "Back to the Future: starring Eric Stoltz". In fact, Stoltz did play Marty McFly in Back to the Future (1985) for a few weeks. Michael J. Fox was originally unavailable, so Stoltz did some filming, but realized that the part was not right for him. By that time, Fox had become available and did the movie. See more »

The First Breach
25 February 2017 | by (Rio de Janeiro, Brazil) – See all my reviews

Dr. Bishop visits Olivia and has a cold reception from her. Walter asks for something to drink and tells the story of Peter. In the 80's, Dr. Bishop designed and built a portal to the alternate universe. When his son Peter dies, he crosses the portal despite the protest of Dr. Carla Warren and Nina Sharp to save the life of the other Peter. He brings the boy to heal him, but his wife Liz does not allow him to return the boy to his mother.

"Peter" is among the best episodes of "Fringe" and maybe will be a turning point in the story. How Olivia, who shows feelings for Peter, will react to the discovery that he was born on the other universe is a good question. How the gate to the alternate universe was opened and the problem with Nina's hand is also shown in this episode. Dr. Bishop 's true personality and behavior and why he changed his personality is disclosed piece by piece. My vote is nine.

Title (Brazil): "Peter"
