Was he talking to himself? Great, a really hot new guy arrives and he is crazy. Caroline kicked herself for not leaving him be, and going to Starbucks like she originally planned. Oh wait...she was trying to be a good vampire right? Which meant helping people?
Of course all her ideas of being nice to him, went right out the window when he called her creature. Caroline was well aware she wasn't human, and she was more on the monster side of things than anything else - but really? She couldn't help but laugh though at the threat, because in all honesty the situation was pretty bizarre. Here she was a vampire and here he was, whatever he was, looking like Brad Pitt with a gigantic sword. It reminded Caroline of something the anime geeks at her school would carry around - only theirs were obviously much, much stronger.
"Call me creature again," Caroline said, crossing her arms over her chest. "And I'll do things to you that you have never dreamed of." All it would take was eye contact and a few choice words and Caroline could have him clucking like a chicken, or doing anything else she saw fit. Which would be mean even for her, but still she could do it.
"My name is Caroline, and if you want me to help you, that is how you'll address me," she said sternly her eyes narrowing. "You can try and kill me, and I mean try but I doubt you'll even get close."
She tilted her head to the side. Hoping she was right about the last bit. She had superspeed and superstrength, but she really had no idea what the sword could do. Maybe she should have paid more attention to Matt's video games and comics.
"You are in Lawrence, Kansas. Which I'm gonna guess means absolutely nothing to you. You're here because someone broke one of the 66 seals to hell. And I had nothing to do with it, I was brought here just like you."
