Fringe (2008)

And Those We Left Behind - S4-E6

Plot hole: The very ending scene where Peter (in this version died in the ice as a boy so Walter's wife never met him) takes off some of the dust covers then picks up a toy airplane. The toy airplane he got as a child from ... Walter's wife when she was trying to placate him in an earlier episode for trying to run "home". This toy airplane wouldn't have been his as a child in this version of the universe. (00:42:00)

Phillip Broyles: Someone out there is experimenting, only the whole world is their lab.

Trivia: The icons shown during each commercial break each have a letter meaning. By the end of the episode, all the icons shown will spell out a codeword. For example, the glyph solution for the pilot episode is "OBSERVER".
