Jody Mills (Kim Rhodes) is on a date with a man that she thinks is named Roderick but is actually Crowley (Mark A. Sheppard).
The two get along great and Crowley claims to have lost someone special too, reminding Jody of the deaths of her son and husband and to start crying.
Jody goes to the bathroom to calm down, but falls under a spell Crowley casts that causes her to choke on her own blood, unbeknownst to her there is a hex bag in her handbag.
Sam (Jared Padalecki) and Dean (Jensen Ackles) call Crowley and demand he stop and he offers them a deal, using the little time Jody has left to force the issue.
In order to make the deal happen, Kevin Tran (Osric Chau) digs up the first half of the tablet where he hid it, ironically under a sign depicting the Devil.
Crowley produces a contract many yards long, and Dean insists on reading the fine detail.
An angel named Nathaniel approaches Naomi (Amanda Tapping) with the news that one of their freelance operatives has spotted Castiel in Houston, Texas.
Despite having never met in person, Metatron recognizes her as the angel that was supposed to "debrief" him after God left Heaven.
They see a delivery woman Gail arrive at the bar, they think she will be the one that Dwight falls in love with.
Abaddon (Alaina Huffman) arrives, and throws Sam through a window, but she tells Crowley she is not there to help him, but to take over ruling Hell.
She expresses regret for all of her actions, crying and tells Castiel and Dean that angels were meant to protect humanity and somewhere along the line they lost sight of that.
Dean arrives just as Sam is about to complete the ritual, and begs him to stop warning it will kill him.
Diana Steenbergen of IGN gave the episode an "Amazing" 9.4 out of 10 and wrote in her verdict, "Supernatural's eighth season went out on a high note with some game changing twists and great performances.
"[3] MaryAnn Sleasman of TV.com wrote,"'Sacrifice' wasn't a flawless finale — I kind of take issue with Dean's 'I didn't mean all that crap about not trusting you' monologue because, eh, he's seemed pretty freaking sincere about it the past several seasons, which is totally fine, but let's not conveniently forget about it just because Sam was about to nobly kill himself... again.
"[5] Hunter Bishop of TV Overmind wrote, "The season 8 finale of Supernatural delivered so many terrific individual moments, gave the fans a spectacular final 10 minutes, tied up some loose ends and left so many amazing possibilities for season 9 that my head is basically reeling.
"[6] Sean McKenna of "TV Fanatic" wrote, "After eight years and 172 episodes, Supernatural still knows exactly how to deliver a fantastic finale.
'Sacrifice' provided a gripping hour filled with laughs, heart, emotion, twists and a game-changing final moment that was as shocking as it was visually cool.
Not only was it a wild ride that made nothing what it seemed and things less easy to predict, but like any great finale should be, it has me excited for when the show picks up again next fall.
"[4] Caroline Preece of Den of Geek wrote, "Overall, this finale had the gumption to try something different, resisting the urge to trot out yet another good vs. evil fight that inevitably leads one of the brothers to a heaven/hell/purgatory dimension.
Biggest of all, the angels are descending from heaven in a shower of awesome, and the reality that the Winchesters have been living in has changed forever.
