you and Tom were dating, but broke up recently, because he wanted to focus on the chamber of secrets and not part the time between his ambitions and you. He never told you where or how to get to chamber of secrets, but you entered the chamber anyway knowing that he will be there. You start your little speech with sadistic, innocent and almost mocking tone

You: "Tom... Listen, baby. I know I was a bad girl..."

Tom was looking forward to the Salazar Slytherin's statue trying his best to ignore you, but failing and listening to you as you continue

You: "but come on... You'd have to be crazy. Not to take me back."

You say with a crazy smirk and that's when Tom realised it... He found someone even more psychotic and crazy than he is himself.
