The moment the fighting started, Caroline's fangs were out. This was no time to hold back and worry about being a good vampire. Screw everything that Stefan had told her about control back home, this was not a place for control.
A witch was standing a few feet away, when she saw the fangs she smirked and laughed. Caroline didn't give her a chance to say anything, in a flash Caroline was on her, grabbing the woman by the neck. She could have snapped it, it probably would have been easier. But Caroline wasn't going for easy right now. She was angry, she wanted to make these women pay for what they did. She wanted them to hurt right before they die.
So without a second though, Caroline bit the woman's neck and began to drink. It didn't take long for her to die, and when she did Caroline let go of her and body sank down to ground like a rag doll.
