This episode (4x13) was filmed between The Guilty Girl's Handbook (4x08) and Into the Deep (4x09) for unknown reasons.
This is the first time that Noel, Mona and Jenna do not appear in a Halloween Special.
This title is likely a pun to Aldous Huxley's novel Brave New World, written in 1932.
This is the third Halloween episode, the first being The First Secret and the second being, This Is A Dark Ride.
Filming began on May 29, 2013 and ended on June 10, 2013.
