Though the Doctor couldn't smile, he felt a small, silent chuckle leave his body.
"YOU WILL. I WANT YOU TO KILL THE ME OF THE PAST."
"The you of… the past?" The neighbors on the woman's block were coming out of their houses by now, staring at her and the Doctor. "Let's talk somewhere else. Lead the way to your ship…" She whispered to him. He made his way to the TARDIS with the woman trailing behind him. Once inside he explained the basics of the situation. He travelled to the coordinates he first saw her at and used the TARDIS's Temporal Radiation Vaccumer (he thought of that name all by himself you know) to suck in the TARDIS of the past in. And it worked. He heard the bang of the gun, and saw Davros on the monitor, moving by the TARDIS with two other Daleks. Not on my watch! He thought angrily.
Leaving the TARDIS, he chased after Davros as fast as his suit would take him (which wasn't very fast, really).
"HALT!" bellowed the Doctor, full of rage and determination.
"What is it, my valued creation?" Said Davros, still moving forward.
"YOU WILL NOT SAVE THE DOCTOR!"
"My debt to him must be paid, my child. Otherwise, I will not live. You know that."
"DEBT…?"
"Yes. He rescued me on the Crucible, just as it collapsed in on itself. And for some reason, he was a dalek. I have too much respect for that man to let him die. I have longed to be a friend to him, and now I have the chance. If I save him, I will be able to keep him as my friend. Load him up for healing! We shall do everything in our power to keep him alive!" The Doctor—completely shocked and taken aback—slunk out of the area and back into the TARDIS to think about what happened today and fell into a deep sleep in the middle of his thoughts.
