The posters from Peter's Redverse bedroom in "Subject 13" were hung on the wall when Walternate took him back in "Over There (Part 2)" in order to bring a sense of comfort and familiarity to Peter.

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.

Olivia struck James Heath with a candlestick in her dining room, making the title a complete red herring.

Observers send materials to themselves via shipping lanes from the future using metal cubes.

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

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.

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.

The apple glyph can be seen on the backrest of a chair in the lab.

In "And Those We've Left Behind" Peter picked up the same toy plane (perhaps not literally the same) that he played with in "Subject 13".

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