Klaus, didn't really want to kiss her but he had to do what would make her really made and make them start their fight. He was getting a little annoyed with this he said, she said crap about their bodies and who was the hottest and what not. He wanted to fight and kill her, and hopefully the kiss would work. But he saw her and she looked like she was shocked or something. "What? Cat's got your tongue or something? Can't speak now or something? Or am I just a great kisser that you are looking for more?" He said teasing her to see if she would break and whip out those claws of hers.
Of course he wasn't looking to sleep with this person, that was just well, wrong. He liked the ladies, but there was just something about him wanting to sleep with people that he was going to kill either way. Shrugging it off he looked at her once more. "You know we have been wasting so much time just talking, are we trying to get to know each other or something? I have to say that its really not my style." Giving her a little smirk.
Then he saw a man and knew that it must be someone important in this X's life. Turning around he saw him, and he gave a little smile. "Ah I see that you have brought a friend. How nice, I thought it was just going to be us two, but you know what, this is going to be a lot more fun than I anticipated killing two people in one day. How exciting this is all going to be"
