Season 5, episode 9
Writer: Kristin Cantrell
Director: Tommy Gromley (with animation by 6 Point Harness)
Walter Bishop's most epic LSD trip ever an attempt to recover lost memories of his master plan to defeat the Observers allowed Fringe to creatively cut loose with some novel storytelling devices, none more inspired than a cartoon romp rendered in the style of Terry Gilliam's stop-motion Monty Python animation.
