"I have been your sex slave for fifteen years, Eric Northman, and we ain't never had sex!"
It's the aftermath of the big battle, and there's a lot of healing to be done, especially for the bereaved Sookie. This being Bon Temps, it's decided (by Lafayette, mostly) that the solution to this is a party at Sookie's. A good time is had by all, and it's left to Nicole, an outsider, to point out how weird this is, and what awaits place Bon Temps has become.
Eric and Pam meet Sarah Newlin's estranged vampire sister, Amber, who has Hep V. She wants Sarah dead too, which usual ful. But everyone else is partying, except Bull who stands outside experiencing flashbacks from the Civil War. We now learn of his scepticism towards the cause of "freedom" to own other human beings, although of course he must be shown to have such views, or he would lose our sympathies. Interestingly, it is this scene that gives the episode its title as Bill knows the war is futile.
There are lots of little character moments; Andy is finally able to forgive Jessica for what she did. Indeed, the wounds and even the distinction between human and wan pure in Bon Temps appear to be slowly withering away. Good. It's a season about subtle shifts, character development and, I think it's clear by now, no Big Bad. It's refreshing.
There are deeply touching moments; Lettue Mar makes a dignified tribute to Tara. Andy makes a sweet proposal to Holly- and she says yes. There is death, but life goes on. Sookie and Arlene have a lovely long meaningful chat about losing your man. And Jessica sees James and Lafayette, who've grown increasingly close, fucking... and Lafayette stands his ground, insisting that Jessica has been neglecting him and that he deserves as much happiness as straight, white people! As for Jessica, she still has Jason, Violet or no Violet.
Meanwhile, Eric and Pam learn that Sarah Newlin'sparents are truly evil; they're at a fundraiser for Ted Cruz and the far right Republican Party. Fortunately they're all massacred by the Yakuza; things could have got nasty.
The party offends unpleasantly, as Lettie Mae stabs Willa, desperate for her blood. And the episode ends with Eric finding Sarah... and Bill realising he's infected with Hep V.
Another brilliant episode, then, typical of the season. But I'm not sure what the present day "lost cause" was intended to be.
