"Then you should have known what my response would be from the start, Mr. Stilinski." Derek stood up, coming around his desk and crossing his arms. "I don't entertain the thought of having a relationship with any of my students that is not what should be between a teacher and student, because of how illegal it is. So no, Stiles, I am not interested in a romantic or sexual relationship with you. But that doesn't mean that I don't care about you, and you have not been acting like yourself. Now, if this is what is causing you to act the way that you have been, then I need to know that because in that case being around me is not going to be healthy for you. If this is not what has been causing your behavior of late, then I need to know that as well so that I can help you. If you don't feel comfortable talking to me about it then I will find someone else for you to talk to. But I want to know what's wrong."
