Fringe Connections

Walter stole Bell's hand in "Letters of Transit" to gain access to Bell's personal storage unit in "Five-Twenty-Ten".

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

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

In "The End of All Things" September told Peter about Henry, the son he never knew existed, who was born in "Bloodline".

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 flower can be seen outside the entrance to the daycare center.

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.

There are 'Wanted' billboards for the Fringe team.

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

September loads his food with heat (pepper, jalapenos, hot sauce) in "The Arrival" because his emotions are dulled, as he explained in "The Boy Must Live".

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

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

The Glatterflug ad for daily flights to the moon in "Olivia" is the same air travel company as Flight 627 from "Pilot".

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

The entire story of Fringe started in "Peter" when Walter crossed worlds with a boy that wasn't his because he couldn't stand to let Peter die, and the entire story concluded in "An Enemy of Fate" when Walter crossed worlds with a boy that wasn't his knowing that by doing so he would never see Peter again.

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

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

Olivia has excellent aim in "Bound"; she killed Loeb's wife with a single shot to the head. It's stated in "Olivia" that Fauxlivia won an Olympic gold medal for marksmanship.

Jones said there are 10 tests for Olivia in total. The first was a box of lights that Olivia had to turn off with her mind.

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

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".

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

The leaf glyph is on the electronic keypad at Massive Dynamic.
