This is it. No more angst, waffling, or self-doubt. It was the epiphany we've been waiting for.
And it delivered. The title said it all. While it's clearly a passing allusion to the Kansas album "Point of Know Return," it means what it says. Dean's character arc has made its reversal. Both brothers now fully believe that they must fight together to have any chance to win, and they have fully bought into the fact that they are going to fight together, win or lose.
But let's get to a recap.
Downsized
Zachariah is drinking in a bar. A man sitting next to him strikes up a conversation, and they find they both have something in common, they've both been fired. Zachariah goes on one of his patented rants, leaving the man confused for a moment, when the bar begins shaking and bright lights and loud sounds begin. The man and the bartender are in agony, covering their ears, while their eyes are burned out.
But to Zachariah, it's just the boss. And he's offering a chance at redemption.
When it's over, Zachariah walks out happily, over their dead bodies.
Making Peace
Dean has made his peace with the world - he packs up the things important to him to ship to Bobby, before Michael takes over his body and sends the world to ruin.
But not before Sam shows up to stop him. Sam begs him to reconsider, before telling Dean that if he won't reconsider, he will stop him by force. Dean tells him to try, and that Sam doesn't have the extra strength granted by the demon blood now. Sam agrees, and says that's why he brought help.
Dean turns to see Cas, and Cas forehead-touches him to Bobby's.
Reunion
Once at Bobby's, Dean says his piece. He's going to do this, because he doesn't think Sam can hold out forever, and he wants Michael to stop Lucifer before Lucifer can possess Sam and rule the world. Bobby can't believe Dean is giving up, and shows the Winchesters and Castiel his secret - a gun with a single bullet, that he has planned to use to kill himself. The only reason he hasn't, he says, is because he promised Dean he wouldn't. So he will not let Dean give in.
Suddenly Cas senses something, some event that's happening. He disappears, and goes to a forest, where he finds soft ground that looks recently disturbed. He's attacked by two angels, but through a nifty bit of fighting, kills them both. He excavates some of the soft, muddy earth, and finds a hand. After pulling the person out, he takes them to Bobby's.
It's Adam, John's illegitimate son. Adam tells them that he was in heaven, and angels appeared to him, and told him he could save the world. He got offered a deal by Zachariah. Let Michael possess him, and he can save the world, and see his mother again also. The angels also warned him about the Winchesters, that they would lie to him.
Sam asks Cas if that would work. Cas says that it would be a long shot, but it could - Adam is John's bloodline and Sam's brother.
So now there are two problems. Adam wants to join the angels. The human collateral damage doesn't bother him - it's the Devil, and he has to be stopped. Sam tells him there's another way.
"Great, what is it?" Adam asks, skeptically.
"Well, we're working on the power of love," Dean replies sarcastically.
"How's that working?"
"Not well."
Sam interrupts. He begs Adam to give him some time. Adam wants a reason.
"Because we're blood," Sam says.
Adam goes off. John wasn't a father, he was just someone who showed up once a year. His mom is his family. Ironically, the reality he describes isn't far off from Sam and Dean's reality. A lot of time alone, learning to fend for himself. Sam calls him on it, telling him that it was worse living with John. Adam calls BS, he said he would have taken it over no dad at all, no matter what.
Escape
Meanwhile, Dean is shut in the iron room. Sam tells him it's needed, because they can't keep an eye on both of them. Dean says he won't let Adam take his place. Dean says to think about how many people they've killed. He's tired of fighting who he's supposed to be. Sam tells him to think for a moment, instead of trying to sacrifice himself. He says they should stick together.
Dean disagrees. He no longer believes in Sam. He's sure Sam will give in eventually.
"So you're saying I'm not strong enough," Sam says.
"I'm saying you're angry. You're self-righteous." He tells Sam it's just a matter of time.
"Don't do this to me," Sam says. "Not you, of all people."
"I don't want to, but it's the truth. And when Satan takes you over, there's got to be someone there to fight him. And it ain't going to be that kid. So it's gotta be me."
Sam leaves.
Cas goes to check on Dean. The room appears empty. When Cas walks in, Dean shows him the Enochean sigil, presses his palm to it, and zaps Cas out. Dean slips out.
How Cas really feels
Sam discovers Dean is missing, and goes to look for him. Adam is dreaming. He dreams of the playground his mom used to take him to. Zachariah appears, and reminds Adam of his task, and his reward. He tells Adam that Sam and Dean can't be trusted, that they will leave him when things get bad, and that they'd rather save each other than save the planet.
Meanwhile, Dean is wandering the streets. He finds a man preaching on the street. Dean introduces himself, and asks if the man knows who he is.
"Oh, dear God," the man says.
"I'll take that as a yes." Dean tells the man to summon an angel. The man begins praying, when he's put unconscious when he's touched by Cas (touched by an angel, ha!), who says, "You pray too loud."
Cas beats the living crap out of Dean, saying "I rebelled for this! I gave everything for you."
Dean tells Cas to finish him off. Cas relaxes, and puts him unconscious.
Back at Bobby's, Bobby is telling Sam that Adam disappeared before his eyes. Sam wants to know how.
"The angels took him," Cas says as he brings Dean in.
"What happened to him?" Sam asks.
"Me."
Cas says that the angels must have found Adam through Adam tipping them off in a dream.
The beautiful room
Adam is in the room where Dean was taken while Sam broke the final seal. There are cheeseburgers and beer aplenty. Zachariah appears, and Adam wants to know if they are ready. Zachariah tells him he's not needed. He's only bait to get to Dean, not the chosen one.
Adam is upset that Zachariah lied to him. Zachariah tells him that Winchesters have one weakness, and that's family. They'll put aside their differences to try to rescue him, and Dean will be in Zachariah's power.
Adam says he won't let him do it. Zachariah gets upset, and makes him start vomiting blood.
Trust
Sam releases Dean from the iron room, and fills him in. Dean tells him that it's a bad idea - it's either a trap to make him agree, or it's not a trap and he'll agree anyway. Dean tells Sam that if the tables were turned, he'd let Sam - he has let Sam - rot in the room. He asks Sam why he's letting him out.
Sam tells him that Dean is still his big brother.
They go to the room, and abandoned muffler factory in Van Nuys, California. Cas tells them there are 5 angels inside, but he will take care of them.
"Isn't that like suicide?" Dean asks.
"Maybe, but then I won't have to watch you fail," Cas says. "Sorry, Dean, but I don't the same faith in you that Sam does."
Cas removes his tie, and pulls out a boxcutter.
Cut to Cas walking inside. He gets attacked, but he kills his attacker. Four more attack. Cas drops his knife, and asks them what they're waiting for. As they move in, he rips off his shirt to reveal the Enochean sigil cut into his chest. He places his hand in it, and they all disappear.
Dean waits until all is clear, then move in. He finds Adam. Adam tells him it's a trap.
"I figured," Dean says.
Zachariah appears, saying, "Please, Dean, did you think it would be this easy?"
"Did you?" Dean asks, as Sam attacks from behind. But Zachariah is ready, and throws Sam against the wall. He makes Adam vomit more blood, then Sam. Dean tells him to stop.
Dean agrees. He will become Michael's vessel.
Zachariah doesn't believe him. Dean asks if he looks like he's lying.
Zachariah calls Michael. The room lights up, and begins shaking. Dean looks at Sam, who is staring at him in shock.
Dean stares back, as Zachariah finishes, smirking. But Dean, with the hint of a smile, winks at Sam.
"Of course, I have a few conditions," Dean says. He wants guaranteed safety for a list of people. Zachariah agrees. Dean continues. "But most of all, Michael can't have me, until he disintegrates you."
Zachariah is now the one in shock. He says that Michael won't go for it. But Dean asks him, who's more important?
Zachariah grabs him. "Do you know who I am, after I deliver you to him?"
"Expendable."
Zachariah scoffs. "Michael isn't going to kill me."
"Maybe not. But I am," Dean says, and drops an angel-killing knife down his sleeve, and stabs Zachariah in the throat with it. Zachariah dies.
As the light grows brighter and the horrible high=-itched squeal starts, Dean grabs Sam, and asks Adam if he can walk. Adam can. Dean takes Sam out the door, but Adam pauses, in awe of the light. He recovers, but as he reaches the door, it slams, and Adam can't open it. He calls to Dean.
Dean drops Sam, and tells Adam he'll get him out. But it's too late, the light is overwhelming, and Adam turns in horror toward it. Outside the room, Dean sees a flash around the door, then nothing. He opens the door, and finds an empty room filled with junk.
Aftermath
Sam and Dean drive off. Sam asks if Dean thinks Adam is okay.
"Doubt it," Dean says. Sam agrees. "But we'll get him," Sam says.
Sam wants to know why Dean changed his mind. He could tell Dean meant it when he said yes to Michael.
Dean says it was the stupidest thing. "I looked over at you, and I thought, 'That stupid son-of-a-bitch brought me here.' I just didn't want to let you down."
"I owe you an apology," Dean says.
"No, it's..."
"Just let me say this. I don't know if it's being a big brother, or what, but to me you've always been this snot-nosed kid I better keep on the straight and narrow. I think we both know that's not you any more. I mean, hell, if you're grown up enough to find faith in me, the least I can do is return the favor.
"So screw destiny, right in the face. I say we take the fight to them, do it our way."
"Sounds good," Sam says.
So there it is, the team is back together. But how exactly can they take the fight to Lucifer and the angels?
