It was time for Lucifer to face Michael and thus it was time for Gabriel to be forced to watch his mates battle each other. To watch one of his mates die and if there was any love for him left in his Father then it wouldn't ve Lucifer. Gabriel needed him to much to ever survive his loss. The mere idea of facing eternity without Lucifer was horrific. The last thousands of years had already been more then he could bare and that was before their reunion. Gabriel didn't know what he would do without Lucifer at his side for all of time but at the same time he didn't know how to deal without Michael. Without the possibility of being reunited.
The loss of Lucifer would be so much worse though then the loss of the possible future with Michael. Not to mention Gabriel couldn't imagine being able to ever forgive Michael for killing Lucifer when after thousands upon thousands of years he had yet to forgive him for merely locking Lucifer up....So no. Lucifer's death would be so much worse. Gabriel's thoughts kept going like that for hours, never ending and never giving him a moment of peace.
In the end Gabriel simply could not sit by and watch, he simply couldn't risk losing Lucifer. And so he did what he had sworn never to do. He took up his sword and went against Michael. Fighting alongside his brother and mate against his brother and former mate. To say Michael was shocked to suddenly be against Gabriel would be an understatement. Never would Michael have imagined having to face Gabriel. Having to face Lucifer was hard enough and he had many millena to prepare for it but not this. Not having to go against both of his mates. That was..It was devastating on a level that he simply couldn't comprehend.
"You would choose him over me, over our Father, over our brothers." Michael voiced his disbelief over Gabriel being there over going against him after hiding for so many centuries.
"Yes, I choose him. Lucifer may have been an idiot who was by far to prideful but at least he had something he was fighting for. All you had was Father's orders. You just followed orders, orders that were more important to you then our bond. You proved how little we mean to you so yes, I choose him and I will spend all of eternity with him."
"Gabriel..That's not what happened. I had to cast Lucifer out. He incited civil war. He wanted to kill the humans...I loved him than and now but I had to protect our siblings and the mortals..I still love him just as I love you. I have missed you since you left me..I looked for you the moment I felt you leave Heaven,I searched every single inch of the universe for you.I never stopped looking for you....I don't know what he said to you, did to get you to side with him but please..Come back to me, be with me."
"And what, watch you kill Lucifer. My mate, my...everything.I have missed him for thousands of years and I have..hated you for just as long. Just as much as I love you but it means there was never a chance for us. Not since the moment you locked Lucifer in the Cage...No. Not since the moment since you chose Father's orders over our bond, over our love. Lucifer is the one I want to be with and he is the one I shall be with..Goodbye, my brother."
Gabriel and Lucifer attacked as one at once, not letting Michael recover from that blow.
After that the battle was swift as not even Michael was a match to two Archangels. Gabriel got no joy out of it though. Lucifer was safe but Michael was dead. Gabriel fell to the ground and took Michael, Adam, into his arms and cried for the first time since he had been forced to watch Lucifer fall into the Cage. And this was so much worse as there w as no way to ever be reunited with Michael again.
Lucifer looked down at his mate and didn't know how or if Gabriel would want to be comforted by him. He had after all just killed the one Gabriel was mourning and even if Gabriel had been at his side for it. Lucifer knew his brother loved Michael just as much as he loved him no matter what Gabriel had just said to Michael. Hell, Lucifer still loved Michael after everything he had done to him so Gabriel must love him so much more and he had just killed Michale. So Lucifer really had no idea what to do, how to comfort him.
"You don't have to do anything...Just be there for me....and don't ...Just don't say anything to me right now..I just need.. Quite."
Lucifer nodded and sat down beside Gabriel, patiently waiting. It took days before Gabriel was finally able to leave the site of where Michael died. Not before Gabriel turned Michael's body into a star and thrust him into the sky, so that he would be forever looking down at them.
Once Gabriel returned to his home, the children surrounded him and comforted him while Lucifer felt that Gabriel was taken care of enough. So Lucifer left to take out his frustration on what remained of the mortal world. Which wasn't much as with three Archangels battling instead of the two it was suppose to be. Then Lucifer turned his fury on the demons, wiping them out as a whole.
Gabriel felt what Lucifer was doing and while he mourned for the humans, his grief over Michael was simply to vast to truly be touched by it. Let Lucifer blow of his grief and anger on them all until Gabriel was ready to return to his side once again.

It took years before Gabriel was able to leave his home and the comforting presence of his children and the visits that he eventually allowed from Lucifer. Once he did, he sought out the reality where he had placed Dean and Castiel. The Doctor Sexy M.D reality. Where it actually existed. Deanno and his little brother who could had no idea of their real lives or what had been going on the last years. All they knew was that Dean was a mechanic and volunteer fire fighter and he had a male lover, Cas who was a teacher at the university.His best friend was Doctor Sexy Nothing else existed for either. They were happy and in love and they enjoyed their lives together. With nothing that could possibly ever tear them apart.
It had never been Gabriel's intention to come to them and ruin it but he needed to tell them. Needed for them to know what had happened. SO he appeared in front of them in their apartment and restored their memories. Their reactions were violent and messy. Though only Dean tried to attack him, stopped only by Castiel grabbing his arm. As his brother was well aware that nothing Dean could do to him would ever possibly hurt him. So Gabriel waited for them to calm down. It took some time and unsurprisingly it was Castiel who spoke first.
"Brother, why have you done this?"
"I did this to keep you safe...You would have gotten in the way of the fight and you would have died and I couldn't allow that. You are a very..interesting and intriquing brother that I have grown quite fond of. So I wanted you out of harms way and as you would not be happy without Dean, I saved him as well..And he does kinda grow on you...He has Michael's good qualities in him, some of the bad as well but so much of the good... Dean can't die.I won't let him."
"I don't care what you want you son of a bitch. You will take me back to Sam or I will,"
"Dean."
"No, Cas. He shoved us into this...Into this tv show again and..."
"Its not a TV show. This is the reality where the TV show is real, just as there is a reality where your life is a TV show."
"Who the Hell would watch...Never ,mind. Take me home now."
"Perhaps you first should hear what has happened there since I brought you here."
Before Dean could speak, Castiel put his hand over his mouth,"Yes, Brother. Tell us what is going on."
So Gabriel did and was not surprised at their reactions. Neither of them took it very well at all. Gabriel could tell though that Dean was ready to explode while Castiel was trying very hard to understand what Gabriel had just told them. He understood why, after all it wasn't every day that one was told that the Earth was now gone, six billion people dead and Michael dead. Not particular happy news. Added to it was the fact that Sam was now host to Lucifer and had been for over many years,meaning that Sam was now nothing. His soul shredded into nothing by the might of Lucifer's Grace. Sam no longer existed.
Finally though Gabriel had enough and just admitted to why he was there.
"So, I came here to tell you this and to make you an offer. I am making you both immortal without or without your consent but the offer is this. I let you remember your true life, let you be yourselves or I take the memories away again. I could let you remember Sam and.. Michael if you want, Cas,Dean. You would remember them as your brothers who died..The choice is yours."
Dean wanted to demand he take them back and bring Sam back but he knew that he didn't want to go back to the barren wasteland that his world had become. And he knew that Gabriel couldn't bring Sam's soul back and that he would not go against Lucifer to get Sam's body back. Not after killing his own brother for Lucifer. Dean truly wanted to kill Gabriel for it but he knew that even if by some miracle he manged to surprise Gabriel, he had no way to kill him. Even if he had access to the Colt, it didn't work. Two years of research had brought no closer clues to a weapon capable of killing an Archangel.
Let alone having the weapon at hand when just thirty minutes ago, he had no idea any of this existed. On the other hand Gabriel could kill him like a human could smush an ant. Hell easier, as he had proven at Mystery Spot, over and over again.
So in the end Dean just let Cas decide, to broken to care about his memories of a brother that was gone and in no way to save him this time again. No demon to deal with. Nothing.
Castiel looked at his ..at Dean and looked inside himself and knew what they both wanted.
"Make us forget..We are..happy here...And there is nothing for us there anymore...Gabriel..I would like to remember you as well...If you would like to come visit again....I would appreciate it."
Gabriel smiled at Castiel, already planning on returning many times to see the only brother outside of Lucifer who had shown any affection for him in a very long time. Then he snapped his fingers and made them forget again. Castiel looked at his brother and while saddened at the news he had told them, he was glad to see him. Michael may be gone but Gabriel was still here.
"Thank you for telling me about Michael's death, Gabriel. You did not have to come here to do so.."
"Of course I did, Bro...You don't tell your little brother that your brother is dead any other way but in person."
"Will you stay longer?"
"Can't....Its time I return to Luc...Its been to long already."
"Your still with him." Dean's tone was disbelieving.
"Dean,you know that Gabriel is bo..married to Luc." Gabriel looked sharply into Castiel, seeing why he had almost said bonding and just saw that it was just how he saw all marriages. Nothing to do with heaven.
There was many goodbyes and promises to return later then Gabriel stepped out of one reality and into another. Once home he immediately went to Lucifer's side.
"Brother, your out of your house." Lucifer's shock was great as Gabriel had not left his home since Michael died years ago.
"Yes, it was time...I'm ready to live my life with you, Lucifer. You are the one I choose and so I should stop mourning and be with you."
"I am glad, Gabriel..I have missed ." Lucifer held out a hand to Gabriel and Gabriel grabbed onto it tightly.
"Lets go home,Lucy. Together...Lets never be parted."
Holding onto Lucifer's hand, Gabriel turned his back o the burning ruinous world and followed his mate to their true family. It was all over and now Gabriel would spend eternity with those that he loved. The ones still living anyway. Nothing else mattered.
