So, after all the deadly mayhem of last week, Kevin wants to go see if his mother is safe. Dean and Sam (but mostly Dean) think it's a bad idea. Crowley probably has demons all around her and is just waiting for Kevin to show up. But it's not like the Winchesters to avoid something just because it's a bad idea, so they drop in on Mama Tran. Crowley does, indeed, have her surrounded by demons. They're incognito as the postman, gardener, and even Mama Tran's friend, but Dean recognizes and dispatches them with his finely honed hunter skills. Mama Tran is having a hard time with the notion that her boy is a Prophet of the Lord, but she's proud and fearless and invites herself on their quest to retrieve the Word of God. First stop: a tattoo shop to get anti-demon tattoos for the Trans.
It turns out Kevin's idea of a "safe" hiding place for the Word is a bus station locker. Naturally, it's been pilfered by the time the motley road trip crew get there. They track it down to a pawn shop, where Mama Tran intimidates the broker into telling them he's since sold the Word to someone else. Just when it looks like the rest of the episode is going to be a boring procedural, a guy named Beau intercepts them and invites them to an auction where the Word, among other items, will be sold. He works for the god Plutus, who favors velour jogging suits and gold chains. At the auction, they're met by an adorable angel named Samandriel who asks Mama Tran to entrust her baby boy to the angels. She chooses to stick with the Winchesters, because the angels kind of did a crap job the last time they were supposed to protect Kevin.
The auction goes downhill pretty quickly. The prices are steep – Odin's brother Vili ends up having to trade in the finger of a frost giant and parts of a virgin just to win his nephew's hammer. The Winchesters and friends don't have near enough currency to offer up. Crowley shows up and offers the moon in exchange for the Word. Like, literally the moon. When Plutus decides to add Kevin to the auction, Mama Tran bids her soul to save her boy. Sold! To the lady with killer maternal instincts. Alas, Crowley's minions burn off her protective tattoo, allowing the King of Hell himself to possess her. Sam battles Vili and Beau with Thor's hammer and seems quite the natural. Dean goes after Mama Tran with the demon-killing knife, but Crowley skedaddles with the Word before he has to carry through with it. Sam's worry grows as Dean later says he wishes he'd killed her with Crowley inside. Unfortunately, the whole ordeal has left Mama Tran an unresponsive shell of her former self. Kevin sneaks away with her before the Winchesters (mostly Dean) can do any more damage.
We also get flashbacks of Dean and Benny hunting their way through Purgatory. Even Benny seems a little worried by how ruthless Dean has become. They eventually track down Castiel, who finally – finally – gets a Dean hug. The poor guy fled upon their entry into Purgatory in order to lure the monsters away from Dean. As to what ultimately happened to Castiel, we get one more tantalizing clue as he's seen losing his grip on someone's arm, calling out Dean's name, possibly as they're all trying to make their escape from Purgatory. Is this the "letting go" Dean mentioned before? Stay tuned for the full recap.
THEN! Dean came back from Purgatory and reunited with Sam. Then he was kind of evasive about just how he survived (he has a secret new vampire friend) and exactly what happened to Castiel (who is either dead or close enough). The Winchesters don't like to talk about their feelings except for when they talk about them all the time. One thing's for sure: Dean came back from Purgatory with a lot more hugs to give out. Kevin Tran became a Prophet of the Lord, got kidnapped by Crowley, managed to escape and then got ignored by Sam for a year. While in demonic captivity, Kevin learned that Crowley had found another Word of God, this one about how to banish all demons from Earth forever. This made Dean feel all tingly.
NOW! Chicago, Illinois. A young woman leads a frail-looking older gentleman to a safe deposit vault. "So sorry to have kept you waiting, Mr. Vili," she says. "It's just been so long since you checked in with us, we had to dig through our archives." He would have gotten there sooner, but he had to stop off in 1939 to pick up his outfit. His deposit box is so old that its number is a single digit: 1. Instead of leaving the room and minding her own business while Mr. Vili sorts through his possessions like she should have, Miss Nosy sticks around she can be nosy and die. She gasps to see what Mr. Vili has pulled out of his deposit box. "Is that... a bone?" she asks. He turns the object this way and that, admiring it. "Not just any bone, my dear - an extremely valuable one." It looks like a rhinoceros horn covered in pork floss. Miss Nosy looks positively queasy, but offers her further assistance to Mr. Vili. He says he would like to make a withdrawal. Miss Nosy smiles, then gasps in horror at whatever Mr. Vili is doing out of frame. The camera suddenly pans right, which means there's about to be a blood splatter on the nearest wall. Aaand... there it is. Right on time. The title card blazes onto the screen.
The Winchesters and the Lord's Littlest Prophet, have stopped off for a nosh somewhere en route to retrieving the Word of God. Dean is chowing down on a burger with what appears to be a whole wheat bun. A whole wheat bun, people. He's farther gone than we thought. We've joined the group in mid-conversation. His cheek bulging like a chipmunk on a walnut binge, Dean mumbles, "Are you kidding me? You're kidding me." Kevin has asked that they swing by home to check on his mother. "It's a day's drive in the opposite direction!" Dean protests, like that's any considerable distance for the Impala. "Yes, I understand we're in a hurry," Kevin says. "Then what's the problem?" Dean asks. "Channing's broken neck is my problem!" Kevin very nearly shouts. Dean rolls his eyes as if Kevin were asking if they could go home to make sure he'd set his DVR correctly. Considering how much his own mother's death has shaped his life, you'd think Dean would be a wee bit more sympathetic. Kevin lowers his voice. "I'd rather not see my mom twisted into a corkscrew."
