Jack wasn't sure whether to feel relieved or disappointed in the news that he hadn't changed. Instead, he decided to go for 'violated'. "You used me." His voice sounded hurt, but he didn't look away from the Doctor. Not yet. He watched his eyes, though, as though trying to catch him in a lie.

"After everything he did to you... did to everyone... and did to me... what makes you think I'd want to help him? Doctor I..." He looked down to the Master, vivid memories flashing at the forefront of his mind. "I don't know what he is to you... But the things he did... I can't forgive that. I don't care what he might have been like once or what you think he can be. To me, as long as I know he's still alive, I'm going to see his face laughing at me and taunting me as he did unspeakable things to my body over and over." He shook his head. "I'm sorry."
