Fringe Connections

In "Brave New World (Part 1)" Walter sat in his old cell at St. Claire's from "Pilot".

Windmark said "Nothing grows from scorched earth" to Walter and then later Walter saw a dandelion growing from rubble outside. He has hope.

A seahorse can be seen on Peter's luggage.

The ship at the end of "Nothing as it Seems" shows creatures from "Unleashed" in cages.

The episode ends with September going into December's apartment, apartment 513, the episode code of the next and final episode of the series.

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

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.

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

Windmark probed Walter's mind so forcefully in "Transilience Thought Unifier Model-11" that it caused blood vessels in Walter's eye to pop. In "Liberty" Michael resisted Windmark's mind probe, and possibly probed Windmark's mind back, causing blood vessels to pop in Windmark's eye.

All of the people in Olivia's mind wear blacks and greys because Cortexiphan subjects have a strong desire to blend in.

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

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

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

A butterfly can be seen painted on the side of a white trash can.

The boy in "Alone in the World" played with the same action figure Peter showed to the Child in "Inner Child".

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

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

The Observers read Nina's phone call from the impressions her sound waves made on the glass in her office in "Anomaly XB-6783746", like Peter did in to hear the phone call Nancy Lewis made in "The Road Not Taken".

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.

A flower 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.

Sam Weiss died 10-15 years earlier in a shootout with Observers trying to protect the radio signal relay used to locate Michael.

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