Fringe Connections

Fauxlivia studied old Fringe cases for intel in "The Box", including Olivia's taped testimony from "Dream Logic".

Madison Square Garden in the Redverse is quarantined in amber.

The apple glyph can be seen on the backrest of a chair in the lab.

William Bell had a bell on his desk in "There's More Than One of Everything" and rang it after he introduced himself to Olivia. He left a similar bell to Nina in his will in "The Box".

Who did the Observer say was "still alive," Peter or Walter?

The frog glyph can be seen on a door in the pocket universe.

Olivia had a horse-riding ribbon in Nina's old photograph in "Novation". Nina rode horses herself in "The Cure" so it stands to reason that Olivia would have done so as well in the timeline where she was raised by Nina.

The episode opened in "Manhatan", seemingly a typo but actually signifying this was an alternate Manhattan.

A butterfly can be seen attacking Mark Young.

Walter had the Cortexiphan subjects stand in a circle around him to activate their abilities in "Over There (Part 1)" just like he did when they were children in "Subject 13".

When Walter explains that his red/blue lensed glasses were created by his friend from Washington, Doctor Jacoby, he's referencing the television show 'Twin Peaks' which also had an eccentric man of science, Doctor Jacoby, who wore red/blue lensed glasses very similar to Walter's.

A seahorse can be seen hanging from the taxi when Walter listens to music.

Olivia's therapist in "Nothing as it Seems" is the same one she had when she was trapped on the other side in "Olivia".

Bell stole Walter's David Bowie album 'The Man Who Sold the World', which describes what Bell did multiple times for his own benefit.

Butterflies can be seen in Etta's apartment.

An ambering device, first (nearly) used by the Blueverse Fringe team in "6B", was seen in Walter's storage vault in "The Bullet that Saved the World".

William Bell's name is partially faded/scratched off of the door to the lab.

A seahorse can be seen on the Bishops' refrigerator.

When Peter left the hospital in "The Last Sam Weiss" he wrote "I am going home" on an envelope, the same phrase he wrote for Elizabeth in "Subject 13" when he tried to return to his home world.

The green and yellow posters in the diner represent how this new timeline with the yellow/amber title sequence is starting to merge with the original timeline with the blue title sequence now that Peter has returned (blue + yellow = green).

The flower glyph can be seen as Olivia and Shapeshifter Charlie fight in the alley.

Walter implanted a tracker in his neck in "Snakehead" which is used in "Grey Matters".

The Fringe team is the First People. Walter sent the parts of the machine back through time via the wormhole in Central Park. That's why the First People had such a knowledge of Peter and Olivia.

The hand glyph can be seen on a door in the pocket universe.
