Later in the kitchen, Sam, Dean, Cas, and Jack are having burgers and beer. Dean tells him how glad they are to have him back, and now that they will soon know where [[Michael]] is, things are starting to look up.
Christmastime in the midseason finale [[14.09 The Spear]], and thanks to [[Garth]] acting as a mole, the boys have a line on [[Michael]]'s location - Hitomi Plaza, a high-rise office building in Kansas City, Missouri. [[Sam]] is concerned over putting Garth in harm's way but Dean reminds him that they're finally a step ahead. [[Ketch]] calls and lets them know he's found the [[Hyperbolic Pulse Generator]] - the "egg"- but was attacked and forced to drop it... in the mail. Unfortunately, the post office is closed due to the Christmas Holiday and the package is stuck in Joplin, Missouri. Since the post office is closed, the opportunity exists to break in and pick it up. While discussing this, Garth calls to tell them that Michael sent some of his people find someone at an old recycling plant north of Omaha, to get a weapon - a spear. Also, he managed to overhear Michael's plan to attack and turn everyone in Kansas City - on Christmas Eve at midnight. With this news, they decide to divide and conquer - Sam and [[Jack]] to Joplin to get the egg, and Dean and [[Castiel]] to the recycling plant to find the [[Spear]], then meet in Kansas City before midnight to stop the attack.
Dean and Cas arrive at the recycling plant, and Cas comments on Dean's recent upbeat mood - even being able to withstand the drive with a broken tape deck. Dean explains that he's fired up after getting Jack back, a no-strings-attached win. Cas reminds him that they have to deal with Michael now, and they're taking a big risk going after the Spear. Dean stops him and reminds him that Michael conned him and trapped him, drowning inside his own body. He didn't understand before what Cas and Sam went through when both were possessed by [[Lucifer]] but now he does, and he'll take it if they can trap him but won't be truly happy until he's dead - and if he kills him. Now that he has the chance to do that, he's good.
They make their way into the recycling building and find remnants of [[Dark Kaia]] camp - a sleeping area and a recently warmed food - but no sign of her. Cas wonders why Michael's forces are not there since they had a head start and wonder if they've already captured her, but there's no sign of a struggle and she wouldn't have gone out without a fight. Dean tries to call Sam but there's no answer when Garth calls to tell him Michael left to back up his forces. Dean tells him they're not at the recycling plant and to call him if they hear anything else. They wonder if the recycling plant was a setup when Cas notices Kaia right behind them, the Spear pointed at the back of Dean's head. Kaia asks why they're here and what they want. Dean tells her she knows what they want, and when Kaia questions their ability to take it from her, Dean tells her they weren't planning to take it from her - they came to ask, turning to face her. Kaia says she will not give it up. Dean moves towards her, causing the Spear to push into his chest and tells her, in that case, to just kill him because the people he cares about, his family, that are in danger from Michael who tortured both of them are going to hurt and kill them, along with thousands of people in Kansas City and the only thing that can stop him is her Spear. Kaia backs the Spear away from his chest while he exhales in relief, and she asks what's in it for her. Cas asks what she wants, and she replies that she wants to go back to the Bad Place - her home. She escaped there originally to get away from the monsters, but here is no different because Michael's monsters won't stop hunting her. Dean agrees to help her, but she still thinks Jack has his powers and can open the rift - and Dean lies and says he still can. Kaia wants assurances but Cas says there aren't any, just as they have no proof she's not hiding something as well - and still believes that she's hiding something regarding her desperation to return. Kaia explains there are people she is bound to protect in the Bad Place - and hands the Spear to Dean telling him that if he doesn't return it she will hunt him down and kill him. Dean asks how he's supposed to find her, and she reminds him he did it before - do it again. Dean's phone rings - Sam - and Kaia disappears. He answers the phone, where Sam explains Michael got the drop on them at the post office, destroyed the egg, and kidnapped Jack.
