"Well get used to it," Sam said, a light tone of humor in his voice. "'Cause I'm not going anywhere. And that means you're just gonna have to keep on caring." That way she'd still be in touch with that side of her that kept her tame. Sam still fully believed that Ruby clung to humanity like no other demon was capable and he was determined to make sure that she never lost touch with that. He'd personally make sure of it.
"Missing your boyfriend isn't stupid at all. In fact, it's encouraged." Another sign of humanity. Very good. "Back in the day? You mean...yeah. Yeah, he probably would have. It was smart not to call on him back then. He wouldn't understand you the way that he does now."
Reaching forward, he placed a hand on Ruby's shoulder and offered her the first warm look he'd been able to create since Faith had gone. She needed it after being sent back there. A bit of comfort. Sam was still not at his best, he was still terrified beyond belief about Faith, but seeing Ruby again gave him hope. And so did her blood. "You're back now. That's all that matters, all right?"
