Bill let Warlow go so that he could rescue Sookie since Lafayette, who was possessed by Sookie's father, was attempting to drown her. Afterwards, Bill tried to recall Warlow but Sookie teleported him to the weird fairy graveyard place that her fairy godmother used to take her earlier in the series. While in the fairy world, Warlow's connection to Lillith through Bill (or is it the other way round?) was broken. We also discover that Warlow only has his vampiric urges during the evening and he forces Sookie to tie him to a gravestone. They talk about stuff before Sookie eventually tells him that she has come to the realization that she is a "danger whore" and proceeds to have sex with him, on top of a grave, while he is still tied to the gravestone. Oh yeah, having sex also causes their nether regions to begin glowing.
At the LAVTF Camp, the Governor and Sarah Newlin watch as Eric and Pam square off. However, instead of attacking each other, they quickly dispatch 2 guards before being subdued. The Governor has Eric taken to a room where he is placed in a cage and bound. He says that he will make Eric face the true death but not before he takes something that Eric cares about from him. They bring Nora in and inject her with a new strain of Hepatitis that is lethal to vampires, known as Hepatitis V and then place her directly in front of Eric, forcing him to watch as she begins to succumb to the virus. Elsewhere, the Governor visits his daughter and promises to find a way to "fix" her. Willa begs her father to place her with in the general population of the Camp because she feels the solitary confinement is worse and she knows a vampire (Tara) who she is friends with and who can help her deal with her new vampire urges. After a heated argument, the Governor gives her what she wants and after playing Connect Four with Tara, Willa is "called" by Eric. Tara explains what that means and Willa rather easily glamors a guard into taking her to Eric's cell. Willa and the guard free Eric and Nora. Eric and Nora switch into the guard and a doctor's clothes respectively. On the way to free the rest of their captive friends, Eric stumbles upon a True Blood bottling room and discovers that they are placing doses of Hepatitis V into each bottle.
Meanwhile, Jason continues his quest to rescue Jessica by smooth talking his way from an LATVF recruiting office directly to the LATVF Camp where he is immediately recognized by Sarah Newlin. (Seriously, how the fuck did Sarah rescind Jason's invitation to Jessica?!?!?!) Jason calmly pretends like he has never met Sarah before and oddly enough she plays along until they are alone. Jason explains that if she blows his cover, then he will tell them everything about her. Later, Sarah has Jason taken to a room where she tells him that she wants him to get acclimated to the type of things that they do at the Camp. In the adjacent room, Jessica is brought in with a male vampire and they are given orders to have sex. The male vampire refuses because Jessica doesn't want to and proclaims that he is a vampire, not a rapist. Sarah orders that he be burnt with a UV spotlight. The happens a couple more times before Jessica gives in and tells him to do it but the male vampire continues to refuse. Jason is trying to maintain his composure during all of this.
Finally, Bill realizes that he has lost his connection to Warlow and decides to call Jessica only to discover that she is missing. He realizes that the vision he had earlier this season is beginning, so he goes down to his dungeon and glamors Professor Takahashi into draining him of all but the last drop of his blood, so that he can commune with Lillith. Bill begs Lillith to show him what he needs to do and she basically tells him to stop being a little bitch about everything and to figure it out for himself. When he wakes up, he drinks the only vial of Warlow's blood that Takahashi had and then goes out in the middle of the day to the Governor's mansion where he forces to guards to kill each other. The Governor does his best impersonation of a HYDRA soldier, exclaiming that if you cut him down, two more will rise up to take his place, before Bill feeds from him and then rips his head off.
Some of the minor storylines continue as well. Sam gives Emma back to her grandmother but Alcide finds out and banishes Sam from returning to his pack's territory. Andy names his surviving daughter Adilyn and then gives her 3 other names Braelyn-Charlaine-Danika in honor of her 3 deceased sisters. Terry gives Lafayette a key to a safety deposit box before Arlene and Holly contact a vampire friend of Holly's who glamors Terry into forgetting basically everything that makes him Terry. He has one day of complete clarity before he is murdered by the dumpster in the back of Merlotte's.
I think that is pretty much it.
