I don't own Doctor Who
I do own vast amounts of laziness
So far, people seem to think that Sofia might be part Time Lord, and part Bad Wolf
"So where are we off to, today?" Sofia asks as she enters the console room last.
"We've got a distress signal to follow coming in from an underground bunker in Utah." The Doctor announces.
"When?"
"2012"
"God, that's so close, I should be what? 26?" Rose wonders.
"Since we have a time machine, I'm gonna go with 19, a mere five years older than me, instead of the old six." Sophie has clearly not forgotten nor forgiven about her sister arriving home a year late. Sorry, one year, two days, 21 hours, 10 minutes and 12 seconds. No need to be so finicky, Soph. I'm the third person point of view narrator; I'm not supposed to address a character, oops.
Rose winces at Sofia's words. Rose has a sneaking suspicion that Sophie's attitude is still being affected by whatever bugged her out in Rome, a week ago, ish, was still bothering her. Rose was right. Every time Sofia closes her eyes, she keeps seeing the life in eyes of her opponent fade away. It haunts her.
"We're here!" The Doctor changes the subject.
"Where are we?" Rose asks.
The Doctor finds a light switch, he flips it. The newly illuminated room reveals to be a sort of alien museum.
"That's a stuffed Slitheen arm!" Rose says in shock.
"Look at that" The Doctor is concentrating on a metal head with a frown.
"What is it?"
"An old friend. Well... enemy. I'm getting old"
"From Earth's companion planet, same orbit, similar life, opposite of Earth at all times, home to the first Cybermen. Gone now." Sofia says in an almost trance like voice.
"How do you know that?" the Doctor looks at the fourteen year old in awe and disbelief.
"I've been reading my way through the TARDIS's library."
In his shock the Doctor touches a display case. Several armed men.
"If they are collecting aliens," Rose whispers, "That makes the Doctor exhibit A."
"Unless that's me" Sofia mumbles to herself.
The three of them are herded into the main man in charge's office. He is handling a weird object and a young British sounding lad is talking to him about it.
"You're holding it wrong" the Doctor says cheerfully.
"Is it dangerous?" In charge guy asks
"No, it just looks silly."
The Doctor goes on to display the object to be musical in origin. Mr. Van Stom introduces himself. The Doctor boasts about how good he is. Rose breaks the two's cat fight up. Mr. Van Stom invites the Doctor to the cage, and sends Rose off with Adam, the Brit.
"I'm following you and the Doctor" Sofia announces to Van Stom in a way that allows for no argument. "There is no way I'm risking getting involved in a three way that has my half-sister in it!"
Considering that Sofia revealed her obsidian blade, and it was hovering rather near his manly hood, Van Stom obliged.
The Doctor, Sofia Tyler and Mr. Van Stom plus some guards and maybe some other personal make their way down/into the cage. Adam and Rose go off to do his lab. No diff between Adam and Rose's interaction between this version and the original. At the cage Van Stom has the Doctor and Sofia left with the "metaltron" alone.
"We can help you" the Doctor says to the 'metaltron'. "I'm the Doctor."
"Doc-tor" the 'metaltron' cuts him off.
The Doctor recognizes the sound of a Dalek. He panics and rushes to the door begging to be let out. Sofia does not share in his mortal terror. Actually she doesn't do anything. She is standing still in shock at the sight of a terrified Time Lord. He shock only increases as the Doctor realizes that Dalek has not killed him yet. She listens as the Doctor admits to killing off both the Daleks and the Time Lords. Sofia watches as the Doctor nearly exterminates the Dalek, only stopped because Mr. Van Stom wants it kept alive.
"Binary vascular system" Mr. Van Stom notes as the Doctor gets scanned. "I have to patent this"
"So that's your game!" The Doctor snarls, "You take alien tech, and patent it!"
"Do you know what my scientists found in a Russian crater? The cure for the common cold. Strictly top secret of course, no need to excite the public."
"That Dalek in your cage is better then you. That Dalek is honest!"
"Better then both of you" Sofia mutters. She says her next statement under her breath, "Rule one: the Doctor lies."
"Well in that case" Van Stom ignores Sofia's comment, "I'll be true to myself." He starts the painful laser scanner thing back on the Doctor.
They get word that the Dalek is out.
"Let me go if you want to live" the Doctor orders to Van Stom. Van Stom complies.
Sofia, the Doctor, and Van Stom make their way to Van Stom's office. [1] From there they see the Dalek, quickly kill off an entire room filled with solders. Sofia numbly takes in the knowledge that Rose apparently revived the Dalek and that the only way to stop the aforementioned Dalek would be to seal off the bulkheads. Sofia can't shake the feeling that she is literally sensing the many deaths as they happen. That feeling terrifies her.
"Sorry, Doctor," Rose's voice is heard, "I'm afraid that I was a bit slow."
'She didn't mention me' Sophie thinks.
"EXTERMINATE!" the Dalek's blaster is heard.
"Rose" the Doctor mutters, barely audible.
Something seems to snap in Sophie.
"YOU KILLED MY SISTER!" she screams as she attacks the Doctor. Sofia pushes him against a wall and presses her knife to his throat. "YOU KILLED HER! SHE'S ALL I HAD, AND YOU KILLED HER!"
The Doctor doesn't argue. He doesn't fight. He agrees. Wait, "all I had"? Neither girl had ever mentioned having parents. He has never seen either parent. The Doctor feels even worse.
"OPEN THE BULKHEAD!" the Dalek orders "OR THE WOMAN YOU LOVE WILL PERISH!"
"Rose!" The Doctor and Sofia act simultaneously.
"You can't get rid of me" Rose says with a weak smile.
"I killed once," the Doctor declares, "I'm not killing her again!" He opens the bulkhead. "Do we have any guns?"
"Yeah," Mr. Van Stom admits, "just one problem; the Dalek is between us and them."
"Just the cataloged ones" Adam speaks up.
"Show me," the Doctor orders.
The two of them go to Adam's lab. Everyone else in the room waits nervously for Rose and the Dalek to arrive. The elevator doors open. The Dalek challenges Van Stom. Sofia joins her sister in the lift. The three of them, Human 19 year old, Dalek, and at this point in the story unknown, make their way up to the highest level.
"HOW DOES IT FEEL?" the Dalek inquires of the sunlight.
"Why don't you find out?" Rose suggests.
The Dalek opens up its casing, and reaches tendrils towards the light. [2]
"Rose, Sophie," the Doctor commands, "Get away from it!"
"It just wants to feel the sunlight!" Rose exclaims.
"That thing killed my people!"
"It's changed! It's not the one pointing a gun at me! What are you changing into Doctor?"
"I thought I lost you" he puts the gun down.
'Why does he get a warm reunion hug?' Sofia thinks bitterly. For her the rest of it all, the Dalek demanding orders for suicide, the trek back to the TARDIS, Adams presence, up until she realizes that Rose wants to bring Adam along.
"He's always wanted to see the stars" Rose is saying.
"Tell him to get a bloody telescope!" Sofia protests, "I refuse to have to attempt to act sociably to someone who thinks that nearly starting World War III is funny! On his first trip he'll probably do something stupid like getting a brain door, and fainting! 'Sides the Doctor was willing to kill you just to eliminate that Dalek! I don't want that pretty boy around while I'm getting my explanation!"
"Two against one, Rose" the Doctor says, for two reasons. One, he doesn't want Adam anyway. Two, he hopes siding with Sophie will spare him the pain of regeneration for a bit longer then the next hour or so. Time is relative in the Vortex.
By this time Adam has run off in fear of Sophie, so bonus!
The three of them pile into the TARDIS. Once the Doctor has got them safely into the Vortex, Sofia drags him into the Library for painful explanation; painful memories for him; painful weaseling for Sophie; and painful awkwardness for Rose.
[1] Well, that's where I think they went in the episode
[2] Not the light, stay away from the light at the end of the tunnel, it's a train!
