The quick solution was exactly what Sam wanted. As much as he knew it would never come to anyone involved, especially not him, Sam couldn't help but wish it were possible. Unfortunately, the cold, hard truth was that there was a very good chance that Sam would never be able to make them all trust or even want to be around him again. He had gotten lucky with Faith; she was giving him another chance. Would everyone else be so willing to do the same?
He understood it. He accepted it. But Sam didn't like it.
"She's, ah...she's gonna be a lot harder to take on with Castiel watching her," Sam informed her. Castiel. He still didn't like him. Sam was holding a grudge over the angel at the moment - or, at least, the part of him that very much still craved Ruby's blood was - and he didn't know how to move past the way he felt. He sort of didn't want to right now.
Sam clasped his hands together and looked down. "Not the way that I love you. But yeah. I did love her." It was stupid. He was stupid. "She was...she was one of us, Faith." He looked out at her, that feeling of betrayal sinking into his chest all over again. "One of us. I'd have died for her just as quick as any of my other family and friends and she just...how could I be so -" He lifted a hand as if to illustrate his point, then halfway decided against it and balled his fist up. "Whoever Ruby was? The version that I considered friend? She's dead to me. That thing out there now is nothing but a monster. That's the way it should be."
