"But Doctor-" Sarah-Jane began, but was cut off the Doctor, "no ifs,ands or buts. I do this one alone, Sarah." "Alright, but come back to me, promise? Please Doctor, stay safe," Sarah-Jane bargained. " Deal," the alien replied. Then Sarah-Jane Smith left the TARDIS. And then the spaceship dematerialize.
And rematerialized unground pacifically under Big Ben. Many spieces of the universe were there and hadn't noticed him because he left the brakes off again. "My wife is such a bad influence," he thought marching out the TARDIS doors, ready to have a fairly substantial argument and he was going to win.
"Excuse me what are you all doing here? If I remember correctly, most of you are not allowed to ever step foot on this planet or are supposed to be dead." The Doctor demanded once he was in the center of the room. "Ah, Doctor! We were wondering when you'd join us," came the sickingly sweet voice of Madam Kovarian.
"Oh shut up, you bitch! I've had enough of your cackling. Tell me why the hell your here! Oh, and by the way my wife is dead and I have no problem killing you now, I also carry a gun now and River showed me how to use it," the Doctor screamed at Kovarian. "Pity, your going to kill me, I just came to rescue River. A task that can not be done without you and me. I suppose she can just stay in the Library forever..." Kovarian sing songed trying to make the time lord guilty. "How and why? What's in it for you?" The time lord questioned, knowing that she would never do anything that she didn't benefit from.
"Oh, straight to business, Doctor?" She teased but seeing it was getting her no where, she continue in a rather annoyed tone. "You'd get your wife back and I would have started my penace for what I did to her."
"And why do you need me?" The Scotsman demanded. "Time Lord DNA, you're the last Time Lord," came the reply. "Your wrong, I'm not the last... The Master survived and plagues me to this day," the Doctor muttered.
"Yes, we've met... But River's your wife... Beside Missy wouldn't want anyone who could stop her from getting you under her control around, would she?... We can bring her home, Doctor. And I know you want that, let me help. I never apologized for what I did and I know I need to..."
Millions of thoughts swirled through his head, as his enemies stared waiting for his decision. 'Why are there so many of my enemies here?' The Doctor thought. 'Kovarian, I get. But everyone else confuses me.'
"I need some time to think Kovarian, I need to think about would River want this, would she forgive me, or would she hate me and never trust me again. I have to think about what my wife would do if she knew that I was excepting help from the Silence... from you."
