The episode starts with a drunk being kicked out of the bar. Before the drunk can make it home however, he gets stopped by a man with a necklace, and when the man touches the necklace, the drunk vanishes, leaving nothing behind but his clothes.

Dean hasn't left the bunker in a week, sticking to rereading everything in the bunker for some way to remove the Mark of Cain. However, Sam convinces him it's time for them to get back in the game, so they head out to check out the strange disappearance we witnessed earlier in the episode. The boys investigate the area the man disappeared from, and even interview a homeless man who thinks the guy was abducted by aliens. They then decide to split up so Sam can check out the guys house while Dean scopes out the bar. Dean meets a woman (surprise, surprise) named Tina, and the two hit it off really well. But when she gets up to leave, she is followed by the necklace man. Dean follows them shortly after, but he's too late. Tina has already vanished and the necklace man is out to get Dean next.

Dean wakes up in a basement somewhere, but he's not the Dean we're familiar. Somehow the necklace man managed to revert Dean back to his 14-year-old self. Teenage Tina is locked in the room next to Dean's, and Dean works to try and find a way out. But before Dean can really try to escape, the necklace guy shows up and takes Tina's cellmate away.

Dean finds a way out just as necklace guy is coming back for another prisoner. Dean wants to get Tina out but she says there isn't time and causes a distraction so Dean can get out and get help. Dean knocks at Sam's hotel room door, and the two of them go out to save Tina.

The great thing is that Dean is relieving puberty all over again. He heard a Taylor Swift song and liked it and he doesn't have the Mark now! He also has no control over his manhood, but he does have a brand new liver now, though drinking age is still 21 Dean, not 14.

They get to witches house and Dean sneaks back in to the basement through the window, while Sam has to find another way in, because, in his words, “I’m way too big to fit in that.” The two meet up inside just in time to meet up with necklace man, aka Hansel. And yes that's Hansel from the story of Hansel and Gretel. Hansel pretends that he wants to help the boys kill the witch, but once they're in the room with her he turns on the boys and helps the witch get them ready to be eaten. You're probably wondering why the witch turns adults into children, instead of just stealing children. Well, it was easier to make a few children disappear in the older days, but now we have Amber Alerts and put kids faces on milk cartons, it's a lot harder to get away with stealing children.

And in normal villain fashion, she continues to ramble on, this time going on about how people taste like chicken and how Europeans and Americans have a different taste to them. She also lets slip that she's in the country on Grand Coven business because of a pesky witch, Rowena.

The boys take this opportunity to get the upper hand in the situation. Dean causes a distraction while Sam pulls out the switchblade. As the fight goes on, Dean gets his hand on the hex bag and turns himself back into his adult self, killing Hansel and shoving the hex bag in the witch's mouth and putting her into her own oven.

Unfortunately, even though the Winchesters have won, Tina is now stuck in her teenage form, However, she's perfectly okay with it because she now gets to redo her crap life. So the boys give her the cash they have and get her to the bus station.

Now the boys are on their own again. Sam is bummed that the Mark is back but he's just happy to have his brother back, though I don't think we'll ever get use to Dean liking "Shake It Off" by T. Swift.
