To say the mark had changed him was an understatement. Oh it had changed him alright. In ways not even he could comprehend. But it all lead up to this. Weeks ago, he'd stumbled across Abaddon. Well, stumbled. She had come to him. Without the blade, he couldn't kill her. But she hadn't harmed him. Surprisingly. She offered him something better. Something he would've originally turned down, but the mark? The marked owned him now. He agreed to be a Knight. Her first Knight, like Cain had been once upon a time. And he had agreed. When it came to 'finding' her, with the blade and Crowley present, Dean had turned on his once mentor and disposed of him with ease. Barely even batting an eyelid. Wiping the blood off on the fine suit. He sheathed the blade in his jeans, before turning back to a Abaddon with a small smirk. "Long live the Queen."
