Woodhouse's name is a reference to famed British writer P.G. Wodehouse, best known for his series of Jeeves and Wooster stories, about a superlative British butler and his rather dimwitted employer.
Pam Poovey (Amber Nash) has a full back tattoo which reads: "For the Angel of Death spread His wings on the Blast, and breathed in the face of the foes He passed; and the eyes of the Sleepers waxed deadly and chill, and their hearts but once heaved, and forever grew still!" This is the third stanza to the poem "The Destruction of Sennacherib" by Lord Byron (George Gordon), an eighteenth century English poet. The poem is a reference to a biblical passage (2nd Kings 18-19) of how God destroyed the Assyrian army before it could attack Jerusalem.
