Anne mentions she once was into vampires, until she met one. She met her first vampire in the Buffy episode "Lie to me", when she called herself "Chanterelle"
In Angel's surveillance shot of Anne and Lindsey, Anne is wearing a Triple 5 Soul sweatshirt, as Gunn does in "The Shroud of Rahmon." Anne's lacks the "555-Soul" line, but "Brooklyn" is visible.
