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.

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

The episode's opening titles have been redone as though it were a show from 1985, complete with an '80s version of the theme tune and decade-specific fringe science topics such as "stealth technology", "virtual reality", and "in-vitro fertilization". See more
