Fringe Connections

Olivia's pregnancy dream in "The Same Old Story" is in a waiting area with giant tulips.

Marshall Bowman had a disk in his hand like John Scott and the woman in 'The Ghost Network'.

A hand can be seen on the wall when Olivia and Peter attack the Observers and Loyalists.

Walter said that Nancy Lewis looked familiar in "The Road Not Taken"; her name is on a height chart in the daycare center where the Cortexiphan trials took place in "Jacksonville".

Mark Young's colleague is wearing a butterfly pin, possibly prompting the subject of his hallucination.

Butterflies can be seen on a box in September's apartment.

A flashback at the end of "Grey Matters" revealed that it was William Bell who removed the pieces of Walter's brain. In "Over There (Part 2)" Bell said he removed the pieces at Walter's own request due to fears about the man he was becoming.

The Fringe team is part of a full-fledged branch of the Department of Defense in the Redverse.

A frog can be seen in Walter's Monty Python trip.

In "Entrada" Fauxlivia was brought back to the Redverse via harmonic transfer with small rods injected into her hands, similar to the harmonic transfer that brought the bridge over in "The Man from the Other Side".

In his dream at the end, young Peter is in bed wearing a jersey with the number 96 on it. The number 96 is the same jersey number that Joshua Jackson wore as Charlie Conway in the Mighty Ducks trilogy.

A frog can be seen outside the entrance to the daycare center.

The Fringe team used the skin-growth toxin from "Ability" as a weapon against the Observers and Loyalists in "The Bullet that Saved the World".

Walter's pose as he listens to the Mozart Requiem is a reference to the iconic Maxell tape advertisement from the '80s.

A butterfly can be seen on a lampshade near the front of Olivia's apartment.

William Bell had a bell on his desk in "There's More Than One of Everything". He rang it after he introduced himself. He did that to prime Olivia to receive his soul should he die in the future. Walter rang that bell in "Os" and Olivia became inhabited by William Bell.

Peter's shared dream state with September looks like an observation deck.

The butterfly glyph can be seen on the wall in the diner where Olivia and Lincoln meet.

In "And Those We've Left Behind" Peter picked up the same toy plane (perhaps not literally the same) that he played with in "Subject 13".

Windmark said "Nothing grows from scorched earth" to Walter and then later Walter saw a dandelion growing from rubble outside. He has hope.

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

September's device in "A Short Story About Love" led Peter to the beacon from "The Arrival".

Sam Weiss died 10-15 years earlier in a shootout with Observers trying to protect the radio signal relay used to locate Michael.

A seahorse can be seen on the Bishops' refrigerator.
