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

The intense amount of Cortexiphan coursing through Olivia in "Brave New World (Part 2)" was able to heal her mortal wound. This was foreshadowed in "Brown Betty" when Olivia was sliced by the same weapon that killed Rachel, yet instead of dying Olivia's skin started to heal itself.

James Heath, a Cortexiphan subject, couldn't control his abilities in "Olivia. In the Lab. With the Revolver.". In "Over There (Part 1)" he had been trained to cure disease instead of cause it.

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

The super-sized cold virus from "Bound" was used as a weapon against the Observers in "An Enemy of Fate".

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