MThe Monk
[Reading a letter from the Doctor] "My dear fellow, I'm sure will you excuse me but I didn't want to say goodbye, as you are obviously going to be very busy for some time." He's right there. "Just in case you still idea's about your master plan, I've taken precautions to stop your time meddling." How could he stop a Mark 4? "Possibly one day in the future, when you've learnt your lesson, I shall return and release you." Release me? Ha! Me? Oh, the old fool. I wonder what he meant by release me? Well, I'll be going.
[But he can't get in. His TARDIS is the same size as the Altar. It's no longer bigger on the inside than the outside]
MThe Monk
[Horrified] Ah! Ah! What's he done? He's taken my dimensional control! He's ruined my time machine! I'm, I'm marooned. Marooned! In 1066. Oh, Doctor. Doctor! Doctor!

Funny. I don't believe much. I'm not sure I believe anything. But right now, belief is all I am. "Virtue is only virtue in extremis"... I take it that your intention is to invade the Earth?
MMonk
The simulations have been run. Earth will be ours.
DSThe Doctor's Simulation
Well, consider this... a warning, on the eve of war. I am the Doctor! I am what stands between you and them!
MMonk
You are not the Doctor. You are not real.
DSThe Doctor's Simulation
You don't have to be real to be the Doctor, as long as you never give up! Long... as you always trick the bad guys into their own traps! And here's the trap you fell into -- your simulation is far too good!
[He picks up the Sonic Suglasses and presents them to the Monk.]
DSThe Doctor's Simulation
D'you see these? They're set to record. I'm blind, you see. So I'm psychically wired into these, so my memory print of the last few hours will still be intact on here! Information about you.
MMonk
You are not real. There is nothing you can do.
DSThe Doctor's Simulation
There's always one thing you can do from inside a computer! Even if you're a jumped up little subroutine, you can do it! You can always... e-mail!
[He pushes them up to his face -- a display on the real Doctor's sunglasses shows that a memory file is uploading.]
MMonk
What are you doing?!
DSThe Doctor's Simulation
I'm doing what everybody does when the world is in danger -- I'm calling the Doctor! Pressing "send"!
