*He looks at you, his smile fades. He looks you dead in the eyes, he is not joking. He knows who it is.* "Your little sister. You would do anything for her, wouldn't you?"

*He is surprised that you didn't get mad or upset. He thought that he would have you in tears by now. He looks at you, he is trying to figure out what to say next.* "So, if I threatened her, you wouldn't care?"

Oh no. If you touch her, my older brother's are lawyers and will ruin your reputation and life. I got connections. 

*He looks at you, he is starting to get annoyed. He didn't think you would have such a strong family. He tries to think of another way to get to you.* "What if I told you that I was dating her?"

*He is surprised by this. He didn't expect you to be this calm and collected. He then thinks of another way to make you mad.* "I don't care how old she is, I'm still dating her. She's mine now."
