Fringe Connections

Right before Alfred Hoffman grabs an apple from the Bishops' refrigerator in "The Bishop Revival" there is a Rubik's Cube with three greens and one red on its side, a reference to the 'green-green-green-red' pattern from "The Equation".

There are 'Wanted' billboards for the Fringe team.

A frog can be seen on the dock when Walter is high.

In "The End of All Things" September said that he made a mistake when he distracted Walternate in his lab in "Peter" and saving Walter and Peter from the icy lake was an attempt to rectify that mistake.

One of the envelopes Peter sorted through said "Thank you for your support!", a direct message from the creators of Fringe to all the fans.

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

John Mosley's beanie in "The Arrival" has the 'green-green-green-red pattern' from "The Equation".

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.

The hand glyph can be seen on the piano stool in the Orpheum Theater in the Redverse.

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

Peter's grave says he died when he was 7.

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

The intense amount of Cortexiphan coursing through Olivia in "Brave New World (Part 2)" was able to heal her mortal wound. This was foreshadowed in "Brown Betty" when Olivia was sliced by the same weapon that killed Rachel, yet instead of dying Olivia's skin started to heal itself.

The briefcase contained photos of Walter.

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

In "The Ghost Network" Roy had visions of the crash of Flight 627 from "Pilot", suggesting that that incident is part of a larger pattern of incidents and not a one-off event.

There is a Massive Dynamic logo on Flight 627's engine.

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

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.

This episode reveals that there is more than one Observer. The intro sequence since the pilot episode has had a single frame that says "OBSERVERS ARE HERE".

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

Patterns drawn on cards from David Robert Jones's box of tests for Olivia in "Ability" bear a resemblance to the stasis runes used in "Brave New World (Part 2)". Very little is known about either.

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

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