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

With the Revolver") and the contents of the next episode references the mystery board game "Clue" on which this movie was based. Clue is also the game that Sam brings to Olivia's apartment to play with her in the middle of the night in that next episode. See more »

Good shows, even great shows, have their ebbs and flows, their ups and downs.

Sometimes the producers will sense that a change of pace is needed and they will, like that famous TV chef, kick an episode up a notch by adding "creative salt." That said, nothing to date in this series prepared me for the raw emotional power of this episode. Wow.

Perhaps it was an inside joke by the writers to feature the marquee for one of the BACK TO THE FUTURE films in their alternate universe, but intended or otherwise the reference was spot on.

In terms of production standards, writing, directing, special effects and even the excellent makeup, this single episode packs the emotional punch of a freight train and as good as anything you might see on the big screen.
