The flutter of wings stirs the air around the two of them, curled up on the couch together, and Adam sleepily lifts his head from the archangel's chest. Sam, Dean and Castiel just left, so he knows it's not them, and Michael is with him. His heart stops when his eyes land on Raphael. "Hello, Adam." The archangel spits out his name like a curse, and Adam sits up immediately, on his guard. "What do you want?" Raphael moves forwards slowly, a dangerous smirk on his face. "Why is one human so special?" Adam sees the blade in the archangel's hand and his eyes narrow. He stands up warily, sliding out from under Michael's protective arm and turning to face Raphael. Michael is already tense; he sensed Raphael from the moment he arrived in the room. Adam steps forwards, ignoring Michael's warning. "You here to kill me?" Raphael holds his hand out, inches from Adam's forehead, and nods. Adam backs away slightly and Raphael moves forwards. He knows it was going to happen sometime, he'd bonded with Michael, for fuck's sake; but why did it have to be now? Raphael's hand is inches from Adam when the archangel is knocked sideways by something. Not something, someone. Michael stands in front of Adam protectively, his wings spreading. Huge, white, about six of them, and very, very real.
Michael holds another angel blade in his hand, similar to Raphael's, and he is practically growling at the other archangel. The air around them crackles with electricity and Adam holds his breath. Michael moves forwards a few steps, and this time it's Raphael's turn to back away, until he is cornered. Or so Michael thinks. He is knocked off balance by a huge bolt of lightning, and literally thrown into the wall on the other side of the room. In the next second, Raphael is standing over him, one blade at his throat, the other at his heart. "You would kill your own brother for a runt? A mud monkey?" Michael is about to reply when Adam attacks Raphael. Literally. He jumps on the archangel, wrapping his arms around his neck from behind and squeezing. It doesn't bother Raphael, obviously, but something cutting off his air supply is annoying; like a mosquito. The archangel reaches behind him and grabs Adam bodily by the back of his neck, throwing him over his head and across the room. It's lucky for Adam that he hits the thick curtains either side of the window. He crumples to the floor, blood starting to trickle from his nose from where he hit it on the window frame. Broken, but Michael can fix it. If neither of them die first.
Michael thrashes under Raphael's weight, his chin tilting up slightly when Raphael lays the blade across his neck and presses gently. Not enough to kill him, but a thin line appears across his throat and blood starts to bead up. But then Adam starts to talk.
"Why? Why is one human worth killing the leader of the fucking Heavenly Host? God's eldest son, Raphael. I'm not, am I? I'm not worth his life. Not worth one drop of his blood. You know as well as I do what your Father will do to you if you kill Michael." As he speaks, Adam edges closer and closer to the blade Raphael dropped last time he jumped on him. Michael shakes his head with a small noise when the blade presses further. Raphael just laughs at Adam; a laugh full of hatred, fury, and a hint of fear. Raphael does know what his Father will do to him for killing Michael. But he is willing to sacrifice everything, his brother's life, his own life, in his attempts to destroy the Winchester bloodline. Michael's hands go to try and push Raphael's away from his throat, Adam still trying to plead with Raphael - but the archangel is too set in his decision to kill both of them, if he needs to. He lifts the blade off Michael's throat, and it is about to pierce his heart, when the blond boy flies at him and knocks him very slightly off balance. Raphael misses, his blade stabbing into the floor next to Michael's head. Adam doesn't miss; his blade goes through Raphael's throat. "Don't you ever touch Michael."
When he's sure Raphael's dead, Adam lets go of the blade, and the archangel falls. The hunter stands for a moment, trembling, before his legs fold under him and he collapses in front of Michael, who is sitting by this time. Adam crawls into his lap, hugging him tightly enough that he hisses with pain from the small wounds Raphael managed to inflict. The blond whispers an apology and loosens his arms very slightly. "No-one hurts you. Not while I'm breathing." Michael worries because that sounds a lot like a challenge, and Adam's death is something he could never watch. Adam peppers tiny kisses over Michael's face and he knows he can't tell the boy off, because he did save his life. He focuses his Grace into his injuries until they are gone, and the two of them stay exactly where they are. Just Adam holding onto Michael and whispering into his hair: "Don't leave me. Don't you ever leave me."
