Mr. Malfoy. I realise that you have been through an extremely traumatic situation. Unfortunately, you are not in the ideal condition to travel again yet. Are you telling me that you prefer to withhold information that could lead to the capture of the people responsible for torturing you? If you'll forgive me for saying so, that seems downright mental. But if you'd rather remain silent until you can be relocated to St. Mungo's, you can be my fucking guest.

[He pulled up a chair in front of the older man, sat down, and folded his arms across his chest.]
