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
