Zachariah did plant that vision in Chuck's head, but it was the truth. They did lose Michael's sword and had no idea where to find it, until now since they had delivered it to them. Dean tells him they don't have it, and Zachariah goes for the mind blowing plot twist. "It's you." Dean's confused look invites more explanation. Zachariah can't believe Dean thought he could kill Lucifer. "You simpering wad of insecurity and self-loathing?" H e's just a human. Dean , instead of going after Zack for his smug attitude, instead wants know how he's the sword. Why he's the vessel of course ! The one that Michael's going to inhabit so he can kill Lucifer, just like old times. Dean shrugs, says what the hell and surrenders himself for whatever duty is needed from him . Ha, right!
"Life as an angel condom. That's real fun." No, Dean instead does something really freaking awesome. He draws that line and nothing, nothing will sway him. Zachariah gets dirty. He lifts his finger and breaks Sam's legs. Then he starts barking orders. Michael will take his vessel and lead the charge. Dean's concerned about the millions of humans that will die in the crossfire. Zack contends with Lucifer unchecked they all will. That's not enough for Dean, who figures out Michael can 't take him over unless he gives him permission. Dean's convinced there's another way. Zachariah says there isn't, but the dude hasn't exactly been honest so no one believes him . "Michael must defeat the serpent. It's is written."
Dean shrugs. "Well, maybe. On the other hand, eat me." Oh Dean, such a way with words. He says the answer is no. Sam nervously watches from the ground, wondering how this is all going to play out. We're right there with you Sammy! Zack dangles Bobby's recovery next. Dean says no. He said he can heal Dean, and then gives him stage 4 stomach cancer. Dean falls to his knees , doubling over in pain, and after chok ing up blood says no. Zachariah goes for the gusto, Dean's greatest weakness. "Then let's get really creative, let's see how Sam does without his lungs." Sam suddenly starts gasping for air , floundering on the floor like a fish out of water. Zack holds Dean by the chin and tells him he's going to say yes. "Just kill us," Dean says. Nope, Zack is just getting started.
Now for the really freaking awesome part. There's a burst of white light and suddenly one of Zack's henchmen is dead with a neck wound. It's Castiel! He's pissed! Stunt angel #2 goes for him but Castiel pounds the crap out of him and then in spectacular fashion holds the dude's head down and plunges the angel killing dagger into the back of his neck. He zaps away in an explosion of light. Dean watches in disbelief. Zack watches in disbelief. Sam is too busy succumbing to lack of air to watch and yes, SAM DIES AGAIN.
Zack, very shocked by all this, asks Castiel how he's alive. "That's a good question. How did these two end up on that airplane? Another good question, as the angels didn't do it. I think we both know the answer, don't we?" Zack is now scared shitless. "Noooo. That's not possible." Take that you asshole, messing with Winchesters and all of humanity like that. Castiel lays down the law. "It scares you, well it should. Now put these boys back together and go. I won't ask twice." Whoo hoo! You tell him Cas!
There are the sounds of wings flapping and Dean is no longer doubled over in pain and Sam is no longer dead. That's a definite improvement to their situation. Castiel warns them they need to be careful. Duh! It takes an almighty angel to figure that out? Dean admits the angels are bigger dicks than he thought, but that's not what Cas is talking about. Lucifer is circling his vessel right now. Once that happens, the hex bags won't be enough to protect them. He touches Sam and Dean on their chests and they both wince in pain. Why do angels like doing that? Castiel tells him he's protected them with an Enochian sigil that will hide them from everyone in creation, including Lucifer. "You branded us?" Dean asks . "I carved it into your ribs." That works!
Sam has more pressing questions. "Hey Cas, were you really dead?" "Yes," he admits. Dean asks how is he back, but Cas gives him an unnerved look and flies away. I think we've figured out by now that in angel code, flying away means "I have no freaking idea."
Meanwhile, back in Delaware (that gets funnier each time I say it) , Nick is in bed. He opens his eyes and sees a woman there in a white nightgown. He's dreaming, but that doesn't mean it isn't real. Interesting how angels love talking through dreams. Does that mess with people's heads better?
"Sarah?" He asks. The woman admits she is not his wife. She's an angel. Her /his name is Lucifer. Nick doesn't fall for that so easily. "Sure. Naturally. Um, could you do me a favor there Satan and remind me to quit drinking before I go to bed?" If I were seeing the devil in my dreams , drinking would not be my problem.
Sarah keeps the heavenly act going, telling him he's special. Aren't we all? Oh, but there's very few people like him. He's a vessel, a very powerful vessel. Tell me, what does it take to become a vessel. Is there some sort of training, or did it happen because my great grandparents got in a heap of trouble a while back and did some weird thing with crystals and an Ouija board to get out of it?
I know, back to Nick. Lucifer needs to take control of his mind and body. He/she even admits it won't be pleasant for him. You got to appreciate the honesty. Nick wants to wake up now, but this is real . This is where Lucifer really pours on the sweetness act. Watch the master in action. He/she tells him not to be afraid, this is his choice. He/she sits next to him on the bed, so gentle, so calm, so nailing this.
