Lucifer looked out the window to see about a hundred seraphs attacking the men outside. The other world's Michael was nowhere in sight, nor could Lucifer sense his Grace.

"We have to stop them," Dean said before heading out of the door, having already taken his gun and angel blade out. He'd kept both close from the moment they entered his world.

"Wait. Don't be an idiot," Lucifer said. It was too late by then. Dean was out the door. "Bloody Hell."

Lucifer immediately walked out, along with the others. They watched as several men were smote. "Michael, if you wouldn't mind. My Grace has improved greatly, but not enough to take out a hundred seraphs without putting me into a coma. But leave one alive."

Michael nodded and snapped his fingers. All accept for one angel imploded.

Lucifer immediately went to the last angel, who tried and failed to fly away. He picked him up the collar of his jacket and roughly brought him to his feet. "Hello, Virgil. So wonderful to see you. I see you're having some problems leaving."

"It's n…not possible. Michael took your Grace," Virgil said.

"I'm afraid that's a case of mistaken identity. I'm not too insulted though. It seems to happen often. Now, how about you send for Michael. See, we need to have a little chat with him. Oh, but do leave names out of the mix. I'll know if you don't," Lucifer said. To exercise his point, he brought his blade to the angel's throat.

"H…he'll kill me."

"Oh, no, you needn't worry about that. You'll already be dead by then. Consider it a mercy. I'll do it quickly. He won't," Lucifer said.

Terror appeared on Virgil's face. He knew one way or another, he would die today. But he'd known those who'd been subjected to both Michael and Lucifer when they were angry. They were far from merciful if they were fought. Lucifer was promising him a quick death. He'd take that over whatever either archangel might give him if he fought. So, he did what was commanded of him. "He's coming."

"Thank you," Lucifer said before stabbing the angel in the chest and watching the bright white eyes leave him. He didn't like killing any angel, but the ones in this world were out of control, they needed to be stopped.

Lucifer turned to his brothers. "Stifle your Grace. Let's surprise the bastard."

All three of the remaining archangels nodded and vanished their blades.

"I would suggest all humans leave now," Amenadiel said.

"We're not going anywhere," Dean said firmly.

"We ain't being driven away either," Bobby stated.

"Then we're not responsible if any of you end up dead," Michael said.

Just then, they all heard a flutter of wings before the other version of Michael appeared right in front of Lucifer. "Well, I see you've returned, and you've managed to get your Grace back. You'd think you would've been smarter than that. Was beating you twice not enough?"

Lucifer laughed. "Look who's talking. You can't even tell the difference." His Michael had been crazy as hell for months, and he still knew the difference. There was obviously a deficiency in this version.

Alternate Michael sneered in response. "Not only have you come back here after I beat you, you're working with humans. You sure have fallen far, brother."

"Have I? Look at you. The commander of Heaven, the archangel who bowed down and promised to protect humanity, has destroyed it. Well, at least you tried to," Lucifer said.

"These people aren't worth protecting. You said so yourself. But you weren't either. You were nothing but a whining little brat. I should've let father kill you, like he wanted," the alternate Michael snarled.

Michael barely kept the façade up. He wanted to defend his brother, and he wanted to smite the other version of himself. How could this being even consider having let something like that happen? He would never allow anyone to harm his little brother.

"But I finally killed you, and I will again. After I use you to enter your world," Alternate Michael said with a smug look on his face.

"Are you certain of that? I mean that you killed your world's me. See, because I think you killed the imposter, and I'm somewhere with a blond on each arm," Lucifer said.

Alternate Michael laughed. "Yes, I heard that theory. That you created some being and infused your Grace into it. It was very inventive, even if utterly ridiculous. Anyway, how should we do this? You could just give in, and then I'd make your death quick, or we could go the way I'd prefer, where I beat you again before stealing your Grace and killing you."

"I've got a better way," Lucifer said before turning and nodded to his brothers.

Michael, Amenadiel, and Gabriel all summoned their blades again and allowed there Grace out.

Alternate Michael gaped in shock. "It's not possible."

"Don't be stupid. Of course, it is. You knew there was another world, one you've wanted to inhabit to change. Is it so farfetched that they would want to come here to stop you?" Lucifer asked.

Without saying a word, alternate Michael used his Grace to send Lucifer flying backwards into the house.

The other three archangels immediately attacked.

Alternate Michael grabbed Gabriel by the arm as he raised his blade to him and punched him hard, sending him back several feet.

Sam immediately ran to help his boyfriend.

Michael and alternate Michael both grabbed each other. "You should be on my side. We are the same," alternate Michael said.

"I will never be like you! I would sooner die than see the world come to this. I would sooner die than harm my own brother the way you claim to have yours!" Michael said. Yes, he had tried to do so do to his own insanity, something he still wrestled with, but this monster seemed gleeful about what he'd done. He had no qualms about killing the angel he'd raised.

"Then you're weak! He deserved it! These insects deserve it! They are undeserving of what they've been given!" Alternate Michael snarled.

Just then, Amenadiel launched a punch at the alternate version of his twin. "You think you're deserving? You are everything I misjudged my twin for being. You're an idiot who thinks he is entitled to whatever he wants!

Alternate Michael pulled himself up and smirked. "I am. I am the leader of Heaven. My word, my rule, is law."

"Not anymore," Michael said.

"I will not allow you to destroy what I've worked for. I will kill all of you! Then I will go to your world and rule of that one, as I have here. I hear there's also a young Nephilim there for me to get my hands on.

Lucifer gripped alternate Michael by the back of the neck. "You will never so much as see my son's face!"

Alternate Michael laughed. "What do you think he will say when I tell him I've destroyed you, and that he now belongs to me?" he asked. He grabbed him by the arm that held his blade and used his other arm to grab onto his alternate brother's head in an attempt to smite him. Before he could do it though, he was thrown through the air.

Michael and Amenadiel approached him. "You are certainly cocky. There are three of us, yet you think you can beat us?"

Alternate Michael laughed and pulled himself to his feet. "I think my odds are pretty good. You can't kill me. You think exactly like me. Lucifer and Gabriel are too low on Grace. I can feel it. That leaves Amenadiel. He's just as powerful as me, and he's a coward. I think I'll be fine." He used his power of telekinesis to throw both Michael and Amenadiel away from him.

Lucifer circled around his alternate brother.

"I figured I'd start with you. Kill you just as I did the first time," Michael said smugly.

Lucifer laughed. "Still thinking you killed me. It's quite hilarious."

"I did, just as the prophecy said."

"Ah, but that's not exactly what it said. Father predicted that one of us would kill the other, not which one would die. You know, at first, I thought it was subjective, and that it wouldn't actually happen. After all, I had no intention of falling Dad's plane. I'm sure the Winchesters even believed they'd circumvented it, but I wonder if it's happening, nonetheless. Perhaps this is the moment the final plan speaks of. It never did say what world it would take place in, did it?" Lucifer asked.

"It doesn't matter. I'll still win," Alternate Michael said.

"Well, let us see how that theory works out," Lucifer said before lifting his arm and going to stab the other archangel with it.

Alternate Michael summoned his own blade and did the same. He managed to dodge the jab from Lucifer and stab him in the arm.

Lucifer yelled out in pain, but he wasn't deterred. He kicked Alternate Michael in the arm, causing him to drop his blade, before grabbing him by the throat.

Alternate Michael tried again to smite Lucifer, but Lucifer was quicker. He pulled his sword back and plunged it into alternate Michael's chest, causing a bright white light to engulf his vessel.

Lucifer let him fall to the ground and watched as the outline of his wings was burned into it.

The three archangels immediately ran to Lucifer's side. "Samael, are you okay?"

"Yes. Apparently, the smug bastard was wrong about who would be the winner," Lucifer said before grabbing onto his bleeding arm. It wouldn't do any lasting damage, as it wasn't a fatal wound, but it still bloody hurt.

"Let me see," Michael said before removing his brother's hand and placing his own over the wound.

Lucifer felt a coolness his arm before the pain went away entirely. "Very much appreciated, brother."

Michael nodded and looked down at his dead alternate self. "I can't believe how different he was. Did he lose his mind worse than I did? Could that have been me if I wasn't locked in the Cage?" He never thought he would be grateful for being locked in the cage and tortured, but if it kept him from becoming this monster, he was glad it happened.

"It doesn't matter. It wasn't you," Lucifer told him.

Meanwhile, Mary and Dean walked over to Sam and Gabriel. "It's finally over," Dean said.

"Yeah," Sam said. It felt like they were in limbo for nearly a year over this whole alternate world thing. Actually, if Sam was being honest, he'd felt like he was in limbo most of his life over one thing or another. Now, he was going to have a chance to move on from that.

The others, including Bobby and Maze soon joined them. "I take it you'll all be going home now."

"You should come to. You can start fresh," Mary said. She'd grown very fond of Bobby since he'd helped rescue her. She didn't want to say goodbye.

Bobby shook his head. "I gotta fix things here. We've got a chance to start over now. Sorry."

"I understand. I'd probably feel the same way," Mary said before hugging her friend.

"If there are any angels left, they will likely flee back to Heaven. You will have a chance to start over," Michael said.

Bobby pulled away from Mary and looked at them. "Won't deny being skeptical about you people, but you came through, even if you had your own agendas. Thanks."

Michael nodded. "I can't deny not caring much for humans, but none of you deserved this."

"Alright, let's get out of here. It's time to return home. I can already hear LA calling for me," Lucifer said. He'd missed home. The Bunker was terribly boring compared, and though he wouldn't admit out loud, he was anxious to see a certain detective again.

"He's right, we should go," Amenadiel said.

They all said their goodbyes and headed back to the rift.

Rowena was quite anxious as she waited for everyone to come back through the rift. Charles had told her that it would be any second now, and she was not looking forward to it. She just knew she was going to be blames for what God had 'gifted' Jack. She certainly wouldn't call it a gift, even if Jack had asked for it, and she doubted Lucifer would.

Honestly, Rowena could hardly believe Jack had asked for this. Who would want that? It was the most insane thing anyone could ever ask for, but apparently the boy had. She supposed it didn't really matter. All that mattered was that she was going to subjected to much anger from the Devil himself.

Rowena watched, and Dean came through the rift first, followed by Sam. "Boys, you're back. Good, there's a little problem."

Dean narrowed his eyes at her. He didn't want a problem. They just took care of the last of months' worth of freaking problems. He didn't want to deal with anything for at least a month. "What problem, and better be something I can deal with quickly.

Sam, meanwhile, turned towards the man he saw seated in a chair a few feet away. "Holy crap."

Before anything else could be said, Mary stepped through, followed by Castiel, Maze, and the four archangel's one by one.

"I just want to say this is not my fault," Rowena said.

"What not your…?" Lucifer cut himself off when he felt it. Suddenly there was sheer power coming from the room, power he'd only ever felt from one being.

"Welcome home, boys," a voice suddenly said.

Lucifer turned to see his father sitting to right holding his son. At least it looked like his son, but he boy was much, much younger than Lucifer left him.
