Both of the dead girls were well known at the club and Sookie meets Eric, the vampire elder. Sam Merlotte seems to have a few eccentricities of his own. Jason buys vampire blood - an aphrodisiac - from Tara's cousin Lafayette and despite clear instructions to never take more than one or two drop at any one time, downs the entire vial with somewhat painful results.

But Jason instead sets his sights on a local woman, named Randi Sue, as his latest sexual conquest.

Sookie must deal with her emotions when her grandmother is the mysterious serial killer's latest victim. She can't block out the thoughts of others and she knows many of the townspeople think the main reason her grandmother is now dead is her association with a vampire. She has a very clear message for them at the woman's funeral. Despite Sam and Bill's pleading, Sookie insists on staying in the house, but she does decide to spend the night with Bill to lose her virginity once and for all. Meanwhile, Jason wrestles with withdrawal symptoms from his 'V Juice' habit, which leads him to lash out at Sookie when he hears about Gram Adele's murder, and he also punches Detective Andy. Also, Tara has a run-in with her drunken mother Lettie Mae at Adele's funeral, who tells her some unsettling facts about herself. Tara then asks Sam to have sex with her at her motel room to look for "something right" between them, while Jason has his night with Randi Sue, and Sookie finally gives in to her carnal desires with Bill.

When Sookie finds Sam asleep without clothes at her bed, he reveals his own secret to her that he happens to be a shape shifter, plus his pet dog seen around the bar is really him in disguise.

Jason decides it's time to do something about the captive Eddie, while Amy thinks differently.
