While Peter and Olivia grieve the loss of Etta, Walter retrieves the tape #7 and heads alone to an apartment building in a derelict zone to bring an essential component of the plan to defeat The Observers. The apartment is the opening to a "pocket universe' where the laws of time and physics do not work. Walter finds a man called Cecil that accidentally felt in this universe twenty years ago but only five days have passed in the pocket universe. Meanwhile Astrid finds the tape and goes with Peter and Olivia to the apartment. Peter and Olivia use the entrance to the pocket universe to seek out Walter while Astrid wait for them. But The Observers have identified Walter on the street and are heading to the area. What will happen next?
"Through the Looking Glass and What Walter Found There" is an episode that recalls "Twilight Zone", with Walter, Peter and Olivia going to a place where the laws of physics and time do not work. The plot is intriguing and well-resolved, and the question now is how Peter will be affected by the device he implanted in his neck. My vote is nine.
