One of the coffins in Malcom's nest (specifically the green marble one) has "Gott ist tot" written repeatedly around its side. "Gott ist tot" is German for "God is dead".
In this episode, Sookie reads the mind of one of the fang bangers at Bill Compton's house. Just before Bill bites him, Sookie announces he has Hep D. In Charlaine Harris's novels, this disease is called Sino-AIDS.
The one and only time in the show that Hep D is ever mentioned.
