He noticed the wary look, but didn't comment on it. It definitely confirmed his suspicions about Faith and gifts. Yet again, he felt a white-hot spike of anger at the people that had hurt Faith in the past. There were very few humans that Pike believed were okay to kill. These people? Might just fall on that list.
He watched as she opened the box, a little smile on his face. "Yup." The smile slowly faded as she stared at it. Oh crap. I fucked up. I fucked it up. Pike's father was to blame for that particular fear. He bit his lip, waiting for her to say something. "I just thought, y'know..." That a Slayer could use a cross that's been consecrated. That it was a practical thing. But those words just weren't coming. They were true, it had been a factor in his decision, but that wasn't why he'd decided to get her a gift. "...you might like it?" His voice was quieter than normal as he finished his thought, and the usually strong, self-assured look he tended to carry himself with was gone. He couldn't quite look her in the eyes, and his heart had sped up just a little bit. He was doing his best to hide it, but he was scared. He was more than used to trying to do something nice for someone and having it shoved back in his face. Again, his father, and to a lesser extent his mother, back when she was around.
But damned if he wasn't fighting through the fear to hope.
