Fringe Connections

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.

There are 'Wanted' billboards for the Fringe team.

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

Walter looked upset when he found Peter's coin in the lake house in "There's More Than One of Everything" because Peter was holding it as he died in "Peter".

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

The combination to Bell's safe in "Concentrate and Ask Again" was 0-5-2-0-1-0, the same combination used in "Five-Twenty-Ten".

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

Senator Van Horn, who died in "Do Shapeshifters Dream of Electric Sheep?", was still alive in the altered timeline and talked to Broyles in "Brave New World (Part 2)".
