The attitude from Castiel only proceeded to piss him off a tiny bit more. Did he not realize how serious this situation was? Ruby was...she was evil. His heart sank a tiny bit at the thought.

She was never your friend, Sam, he reminded himself. Even though he had that knowledge, it was still rather difficult to push away the fact that he had truly believed that she was. Fucking Ruby. She could go to Hell for all he cared.

Maybe he'd send her there himself.

"Killing her might not make all the problems go, but it'll be a damn good start," Sam growled. Castiel, like himself, had forgotten how things were supposed to be. He was a Hunter. Castiel was an angel. It was their job to go after things like Ruby. She was a threat, she had proved that much tonight, and they had to eliminate her. They had to follow their instincts, not their aching hearts. "It needs to be done. She's as bad as Azazel and Lilith were. Maybe even worse." He lifted his chin. If Castiel wanted to take him out, then that was fine. But Sam refused to show him fear.

"Look at me, Castiel," Sam said, voice as even as he could manage. "What do you see? I've..." He grit his teeth and looked down, finally. "I've lost it. I don't know who I am anymore. They don't want this, this thing I've - all I can think about is her blood. I want to drink it and I want to kill her at the same time and it's all so confusing." He brought his hands up to grip at the sides of his head as he turned away from the angel, fingers digging into his hair. He stood with his back turned for a long moment. Then his arms slowly slid to his sides and Sam glanced over his shoulder to look at Castiel. He looked terrified. "What if they don't forgive me?"
