Ruby was happy with that, Between him and the Vampire Slayer he'd be okay, and Faith had never questioned his abilities. She might even encourage him. It might help, and she didn't think he was about to confide in her to that level either, he wouldn't tell Faith what she had asked of him.
She also might have a shot at making him believe he was a good person, Because he didn't believe it.
"That'd be good. Might just be the final kick I need to get back on my feet so we can get back training. Maybe its cause I'm a demon, taking that bit longer or whatever. But when you're out with Faith don't be afraid to use your abilities. You need to learn to be okay with them Sam. Its a big part of it."
