Fringe Connections

The blue powder dispersal doll from "Concentrate and Ask Again" was seen in Walter's storage vault in "The Bullet that Saved the World".

Olivia entered "Martin Luther King/Eldridge Cleaver Memorial Park" which has a plaque quoting them as saying "We have a dream" rather than "I".

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

The Fringe team used the skin-growth toxin from "Ability" as a weapon against the Observers in "An Enemy of Fate".

There are 'Wanted' billboards for the Fringe team.

Butterflies can be seen in Etta's apartment.

Walter checked Peter's eyes for signs of degradation in "Pilot". Jones's eyes showed signs of changing in "There's More Than One of Everything" after he was teleported out of prison.

Michael can show emotion as he cried when he saw Nina's dead body.

The butterfly glyph can be seen near Lincoln in the rail yard.

Olivia noticed the book "Burlap Bear Goes To The Woods" in Max's room in "The Abducted". This is the same book Rachel read to Ella in "Unleashed".

Olivia struck James Heath with a candlestick in her dining room, making the title a complete red herring.

A seahorse can be seen on Peter's luggage.

The password to retrieve Michael in "Black Blotter", "Black Umbrella", came from the poster for Singin' in the Rain, from which September chose his new name (Donald O'Connor) in "The Boy Must Live".

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

A leaf can be seen on the bio-scan monitor at the Liberty Island security checkpoint.

Peter found Olivia in a field of white tulips in "Subject 13", a nod to "White Tulip".

It is true that the Empire State Building's spire really was initially designed for airship docking as it was in the Redverse.

A seahorse pattern can be seen in the toxin's molecular structure.

Nina said that Bell was a father figure to Jones in "There's More Than One of Everything". They finally worked together in "Brave New World (Part 1)".

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

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

The nanites in "Brave New World (Part 1)" have an "X" on them that matches the "X" on the shirt worn by the man Peter freed from Olivia's mind in "Lysergic Acid Diethylamide", suggesting that "Mr. X" from Olivia's mind may have been William Bell (who was ultimately behind the nanites).

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

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