In the beginning of the episode when Paige and Phoebe are talking just outside the building on fire, Phoebe says, "We're not Brody's angels.". This is a nod to the 1970s show Charlie's Angels in which three women solve crimes working for a mysterious millionaire at his private detective agency.
The title is based upon the song "Someone to Watch Over Me" by George Gershwin and Ira Gershwin from the musical "Oh, Kay!".
