"Dean!" You yell, "Dean stop! Come back!"

Tears brim and cascade down your face as you chase after your boyfriend, "Stop! This isn't you!"

"Shut up and get out of my way, Y/N," He hisses, "You don't want to end up like Cas, do you?"

You glance back at the angel, who lies still on the floor with blood coating his face. Your stomach turns, but you pull back your shoulders and stand your ground. This is not Dean, you remind yourself, this is not the man you fell in love with. It's so hard to remember that, however, when the man in front of you has your fiancé's face; when it's his eyes filled with so much rage and hatred.

"I dare you," You say evenly, "I dare you to touch me. Go on." You hold out your arms, baring yourself to him. He looks you up and down, a depraved hunger in his eyes that you've never seen before, "Do it."

"I don't hit women." He says drily.
"You don't hit me. Dean, this isn't you. Listen to me." You say softly, hand reaching out for his, "I can make this better. You just have to let me."

"Let you?" He snarls, "Since when did you ever do anything for me?"

"Since- oh, my god," You laugh humourlessly, "You have no idea what I've done for you. None whatsoever."

"Name one thing you've done for me that hasn't resulted in me or Sam nearly dying. C'mon, give it a go." He taunts. You scoff.

"I gave up everything. My home, my family, my job, my life. All because I loved you." You choke, wiping away your tears, "All because I thought you loved me."

"I don't." Dean says darkly, "I never did."

"You're lying." You say, staring into the mark that scorches his arm and injects darkness into his veins, "It's a lie and you know it. Just because you don't feel the good things anymore-"

"Don't you dare!" He seethes, "Don't. You. Dare."

"It's true." You say softly, and then sigh, turning away, "Dean, I'm done with this. Go. I'm finished – but don't come crawling back when everything you love turns to ashes."

"I don't love anything." And with that, he's gone. The face of the man you loved, filled with all of that hatred, burns in your memory and sears itself into your inner eyelids. An image you'll never forget and a betrayal you'll never forgive.
