Fringe Connections

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.

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

The seahorse glyph can be seen on the back of one of Markham's books.

In "The Human Kind" Walter tested the Observer tech implant on the brain of the Porcupine Man from "Nothing as it Seems".

The crane that crashed during the intro has a Massive Dynamic logo on it.

Peter said "You're going to be fine" to Olivia in "Brown Betty", like Charlie's "You're gonna be fine" message to Olivia in "Dream Logic".

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

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

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.

Donald entered the mine 5 weeks after the invasion and took some rocks. He was described as being in his late 30s, medium height, dark hair. Donald said he was waiting for "a colleague, a scientist from Boston, to meet him." Observers found him and took him away.

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

John Mosley's beanie in "The Arrival" has 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.

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

Despite Walternate's efforts to mold Olivia's mind into Fauxlivia's, Olivia kept seeing Peter and Walter in "Amber 31422". Similarly, in "Alone in the World" Peter didn't exist in the rewritten timeline yet Olivia kept having visions of him.

Olivia pulled up a list of the frozen heads found in S02E04 'Momentum Deferred' and they were all marked with "2E204", a reference to the episode in which they were stolen.

The flower glyph can be seen on the wall in Karen Truss's house.

Walter had the Cortexiphan subjects stand in a circle around him to activate their abilities in "Over There (Part 1)" just like he did when they were children in "Subject 13".

The Child's happy expression drops when he sees the Observer.

A seahorse can be seen on Peter's luggage.
