The Doctor crossed his arms. "You never answered my other question. How did you know who I was?" The Vigilante turned to face him. "That part's easy. A while back, I picked up the energy signature of another TARDIS, one I didn't recognise. I was curious, so I locked onto its signal and, um...yeah, I stalked you." The Doctor blanched. "Yeah, I thought I would get that response. I went along your timeline, past and future, and learnt everything I could." The Vigilante held up a large manilla folder. "Your whole life is in this folder, from the day you were born on Gallifrey to your very last living day. You had a sandwich on that day. Very Hendrix-like." The Doctor's eyebrows shot up. "You know everything about me?"
"Yep. I even know your real name. You know, I was kind of expecting it to be something like Bill. You seem like a Bill kind of guy."
