(Couldn't tell if you meant she walked back into the elevator or up to her room and pressed 9, so I just assumed elevator. If I was wrong, I will edit this. Don't want to screw with the set-up.)

".....Madeline-san, what floor number does it say on your paper? for someone who is a transfer student, you'd think you would want to unpack your things. I would imagine, a trip from somewhere like England would leave any normal girl tired. Yet, you hit the up button a single time. Our discussion finished quick enough, yet you found it necessary to delay getting to your room. Was our discussion that important to you? it was simply casual banter between two people of differing opinions." Light said, pointing out how needless that was. "Alright, I think we need to cut the crap here. I want to know, who and what you are. I will not speak a word more about myself, I refuse to. But I know your entire cover story is bullshit, and that you are possibly not a human being. I would have kept on with the back and forth, but no one is around to hear this. Honestly, the way you set yourself up with "asking for directions" it is like you knew that I would already know all of this and then try to confront you later on, which you might." Light said, deciding to stop playing games. The elevator stopped, the door opened, and then shut. "You have eight floors to explain yourself. Don't think about escaping me, either."
