Draco felt fatigue creep upon him. He didn't know how long he had been standing in that hot, stifling, now claustrophobic room, arguing with Voldemort.
Not exactly arguing.
Arguing implied that two people were quarrelling over a disagreement. Here, it was purely one-sided. Voldemort did all the verbalizing. The fact that Voldemort couldn't use his wand didn't make Voldemort less dangerous. He was as eloquent with words, as he was with his wand.
Draco was subjected to one whole hour of a description of the tortures that awaited him & his loved ones (as if he had any) if he refused to comply with Voldemort's wishes. They were indeed painful to hear &, so assured Voldemort, even worse to experience. But that didn't deter Draco one bit. He wasn't going to kill Harry & that was that. He may be a disagreeable, arrogant, boastful git (in the words of Ron), but he was not a murderer. He said so, to Voldemort.

"Rubbish! You are what your father is. You will be what he wants you to be. Do you think that, when the blood of a murderer flows through you, you will be any different?"

"I am not, & will not be, a murderer!" Draco almost screamed the words out, the anger, frustration & fear, giving an almost hysterical note to his voice.

Voldemort opened his mouth in fury, when Slytherin spoke in a voice goaded beyond measure.

"I've had enough of this boy! Riddle, I leave it to you to bring this boy to his senses. Do what has to be done. Remember, you can use one spell & one spell only, & also how that will affect you." So saying, he abruptly left the room, slamming the door behind him.

Draco was left facing Voldemort alone.
