Changes

Michael, in a new female vessel, has some of his monsters clear out the Hitomi Plaza office building in Kansas City, Missouri, to serve as the base of operations for his upcoming plan to turn everyone in the city into a monster for his army. He meets with two new volunteers to take his enhancement: two werewolves, one of whom he recognizes as a friend of the Winchesters, [[Garth]]. Garth assures Michael that with his family to worry about, all he cares about is protecting them. Later, it's revealed that Garth became a double agent passing information to Sam about Michael's plans. Once Michael witnesses Garth consuming the blood and grace mixture, Michael turns his attention to [[Melanie]], and after learning of Dark Kaia's location, orders her to send out troops to destroy the spear. After learning of Jack and Sam's location, Michael and some of his troops ambush the two. As Jack is dragged away, Michael confronts Sam while holding the [[Hyperbolic Pulse Generator]], easily melting it in his hands in front of Sam before knocking him out.

Back at Hitomi Plaza, Michael explains to Jack that in his weakened state he isn't worth killing. He explains that when his forces invaded Kansas City in Apocalypse World, there was human resistance which resulted in a lot of bloodshed on both sides. This time, he is going to cause a wave of transformation from within, turning the people into vampires or werewolves, essentially making them soldiers in his army no matter what they become. Michael explains that mankind is nothing compared to beings like them and that when his Jack's power finally returns to him and grows he will be the only other being that can come close to understanding him and his power, and that eventually it his loyalty to the Winchesters and mankind will all fade away from him too.

After Jack's escape, Michael waits in his office as night falls, until he begins sensing Castiel's presence. He quickly finds Castiel in the hallways, and proceeds to beat him to a bloody pulp. He drags his limp body back into his office, where Sam and Jack lay in wait. Michael, sensing their presence, stops them from attacking, causing them debilitating pain and forcing them to the ground. With the Kaia's Spear in hand , Dean attacks Michael, who dodges his strikes and knocks Dean to the ground. As Michael is about to show Dean his mistake, Sam slides the spear to him, allowing Dean to cut slash Michael's arm. As Dean advances on Michael, he comes to a sudden stop, unable to strike Michael down. As Michael continues staring at Dean, Dean's vision becomes blurry and he begins seeing visions of his time as Michael before he sudden;y appears in a bar and Michael's female vessel collapses to the floor. Dean snaps the Spear in two, revealing himself as possessed by Michael once more.

Michael explains how when he possessed Dean, he wouldn't stop fighting back, so he left an opening in Dean's mind to possess him again without permission. He needed to break Dean, in order to keep him suppressed for good in his mind. He tells them that Dean is "gone" and his army ready for his command as he snaps his fingers.
