"I know 'cause..." He looked down, mind going over how to properly phrase the statement. Faith certainly had a good point, he wasn't going to deny that, but he downright refused to believe that it was factual. That blood might have impacted him on many levels, but it couldn't possibly have been influencing any of what he had with Faith. That was all done by his own free will. Sam had made the decision to get together with her. He was the one who had admitted that he was indeed in love. Sam would never lie about something as important as the affairs of the heart.
...would he?
"I'm not on it now." That was probably the only thing that Sam had going for him right now. From Faith's perspective. His own, on the other hand, was very confused when it came to whether or not he ought to be fixed up on Ruby's blood or not. Yes, it was bad. Yes, it was evil. Yes, it made him feel absolutely wonderful.
He was thinking about it now. He had to focus on something else. Fast.
Hands shaking a little, he inhaled heavily and tried to keep himself steady. No running off. He would not dash up the stairs, take the mirror back home, and route his way to Ruby's for a fix. He would not, he would not, he would not.
"And I know how I feel now," Sam continued, "I love you, Faith. You've gotta believe me."
