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".

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

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

Peter ran possible futures in "Five-Twenty-Ten" to try to coerce the Observers to be where he wanted them to be just like Milo Stanfield did to his doctors in "The Plateau".

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 radio found in the pocket universe in "Through the Looking Glass and What Walter Found There" was stuck on 6955 kHz, the same frequency as the number station broadcasts in "6955 kHz".

In "6:02 AM EST" Walternate trapped Fauxlivia in the same cell as Olivia was kept in in "Over There (Part 2)".

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

Olivia shot her captors in "The Human Kind" with the bullet she took from Etta in "The Bullet that Saved the World".

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

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

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.

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

A seahorse can be seen on the Bishops' refrigerator.

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

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

In "Grey Matters" Walter's brain pieces were stored the heads of living people. In "Letters of Transit", in the altered timeline, they were stored in Massive Dynamic.
