In "Back to Where You've Never Been" Peter and Lincoln set up the universe portal in the Orpheum Theater, the same place Walter, Olivia, and the Cortexiphan subjects crossed over to rescue Peter in "Over There (Part 1)".

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

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.
