<P> In Season 4, we see the relationship of Sookie and Eric develop after he loses his memory to the witch coven; first, Sookie shelters him in her house from Bill (though the house is technically Eric's). Endeared by the new Eric's innocence and his regret over his previous crimes as a vampire, Sookie eventually enters a sexual relationship with him, though in the Season 4 finale, Sookie is choosing between Eric and Bill, and chooses neither . Sources have said of Season 5 that Sookie's "independent streak" will continue (as Alan Ball, executive producer) claimed in an interview concerning the upcoming season . By the end of the season, Eric has regained his memories, though he retains his memory and part of the gentler personality he had when he was with Sookie . </P> <P> In Season Five, after previously killing Nan Flanagan, Eric and Bill are arrested by the Vampire Authority . However, Nora, Eric's' sister' (with whom he also has a sexual history) rescues them . Later, all three are caught by the Authority . While Eric steers clear of the Sanguinista movement stirring in the authority and attempts to escape, Bill accepts the Book of Lilith and betrays him . Eric manages to successfully escape with Nora and searches for Sookie to enlist her help; in the process, he manages to kill his archenemy Russell Edgington, fulfilling a vengeance that he began when he was still human . He attempts to save Bill but apparently fails . Later, he returns Sookie's house to her for her protection; while she is grateful to him and considers him a friend, she still banishes him from the house, and Eric tells Nora they will stay away from her now . </P> <P> In Season 6, Eric finds his latest threat to be the humans, especially Governor Truman Burrell, who declares war on vampires . In an effort to challenge the Governor's stance on vampires, Eric turns Willa Burrell, Truman's more open - minded daughter . Regardless, the Governor has them both placed in "Vamp Camp", where Eric is later forced to watch his sister, Nora, receive a lethal injection of "Hep V". Eric uses Willa to escape the camp (promising to get her and Pam out) and takes Nora to the Lilith - enhanced Bill, but they are unable to save her . Devastated by her death, Eric violently slaughters the humans running the concentration camp to seek revenge and free both his progenies, among others . Notably, Eric spares Jason Stackhouse, though he kills the vampire Steve Newlin, stating "Every time I lost someone I loved, you were there ." After freeing the imprisoned vampires, Eric flies off to grieve his sister Nora's death in solitude . In the finale, Warlow, the fairy - vampire hybrid whose blood made it possible for Eric and the other vampires to walk in the sun, is killed by Jason to save Sookie . When Warlow dies, the effects of his blood wears off in the vampires who drank it and they are no longer able to walk in the sun . Eric is shown in the sun on a mountain top in Åre, Sweden when Warlow's blood wears off, causing Eric to burn . </P> <P> In Season 7, Pam tracks down Eric, who somehow avoided meeting the true death . However, he has been infected with the Hepatitis V virus . After learning that Sarah Newlin is still alive, he and Pam decide to go after her . Eric and Pam soon learn that Newlin drank the antidote and it permeated her body, making Sarah a living antidote for Hep V. They are forced to work with Yakuza ninjas from the Yakanomo Corporation (the company which originally made True Blood) in order to find her, but neither party trusts the other . Upon capturing Sarah, Eric drinks her blood and rids himself of the Hep V virus . Learning that Bill is dying, Eric secretly reveals the cure (contrary to the Yakuza's wishes) to Sookie and offers to heal Bill, despite their long rivalry; he is stunned when Bill refuses . However, after talking with Bill he understands his motives and tells Sookie to talk with him, making his final peace with both Bill and Sookie . Eric and Pam later kill all of the Yakuza members that want to use Newlin to make a new food source for vampires . By the end of the series, they are running a multibillion - dollar corporation called New Blood, derived from Sarah Newlin's blood, which is both a new vampire food source and a universal cure for Hep V. Eric and Pam tell the world that Sarah got away from them, but they found a drop of her blood to make New Blood with, and thereby save every infected vampire in the world . In actuality, they are keeping Sarah chained in the basement at Fangtasia, and charging vampires small fortunes to feed on her, as she slowly goes insane . All the while, Eric sits on his throne on the Fangtasia stage, relishing his accomplishments . </P>
