The Doctor leads Jack into the adjacent room, leaving Sophie in the main room of the office. She can hear muffled conversation from the two, but mainly just sits in the office, her brain replaying the events of the previous day in her head. She can see the Master crumbled on the floor, the blood pooling in his lap, while the Doctor cradles his limp body. How she even managed to do it, she is unsure, but somehow it happened.
She slumps down in the seat, as the Doctor and Jack step back into the office. "So," Sophie asks, glancing up at the duo, "What have you got? Any way to get me back home?"
Jack comes back and takes the seat next to her, "We're working on it, but there are a few things you need to realise," the Captain says, placing a hand on her knee.
The Doctor leans forward in his seat on the opposite side of the desk. "If we send you home, your parents won't be alive. All of the events that formed your life in your world will go back to normal, including any trauma."
Sophie nods, "I know. And as much as I love my parents, I don't know them. I know you, Theta Sigma, Jack Harkness. You are my family, and I want to get back to them."
The Doctor's eyes widen when Sophie uses his Gallifreyan nickname. "Alright then, follow me." He stands from his desk, and walks right to the TARDIS, not checking to see if anyone is following him. Jack and Sophie obediently head into the ship, and the TARDIS starts to hum.
Sophie presses a hand against the console, and the room brightens. The Doctor looks around, and walks up to the screen on the time rotor. He presses a few different keys on the keyboard, and scans the readings, "That's strange."
"That doesn't sound good," Jack says, walking up and standing behind the Time Lord.
"The TARDIS recognizes Sophie, which, if this were a parallel universe, she shouldn't know her."
"So wait, are you saying this isn't a parallel universe?" Sophie asks, her eyebrows rising. "But then, why doesn't anyone recognize me? And how do you explain my parents being alive?"
"Shut up," the Doctor says, and turns back to the screen. Sophie rolls her eyes, trying not to look affronted. The Time Lord starts typing more furiously on the console, reading faster than a human's eyes can move. He steps back from the time rotor, and clasps his hands behind his back, and begins to pace across the TARDIS floor. "This doesn't make any logical sense."
"Does your life usually make logical sense?" Jack asks, leaning against the console.
The Doctor ignores him, and walks over to the chalkboard on the second walkway on the ship. He turns, and points a piece of chalk at her, "Tell me everything."
Her eyes widen, "About what?"
"Your life, my life, Jack's life. Everything you know about aliens, the universe. Everything."
She tells the Doctor and Jack about every moment in her life, at least those that aren't spoilers. As she tells him the Doctor's face gets more and more pensive, and the smile on Jack's grows. Sophie starts to talk about the Year That Never Was, and hesitates. Jack raises an eyebrow, and she takes a deep breath, and tells the Doctor about how she shot his best friend.
He shrugs, and turns back to the computer. "I'm not seeing much about what could have caused the world to forget you. And the strange appearance of your parents."
"I've got about as much of a clue as you, Doc. That's why I came to you, thought maybe you could figure this out."
"I'm working on it," he grumbles.
"Great, what do I do till then? I can't go back to my old house, I'll say the wrong thing, and my 'parents' will know something is up. And I don't really have anywhere else to go either."
Jack cups her shoulder, "You can stay at the Hub, if you'd like. We have a bunk room, or you could stay in my room, if you'd prefer."
She sighs in relief, "Thanks Jack. The bunk room will be fine."
He smiles, "Don't worry, we'll get this all sorted out."
"With you two on the case, I think that's pretty obvious. I'll always trust you two with my life, no matter what."
Jack drives back to Torchwood. By the time they get there, the rest of the crew has clocked out for the day. Jack glances around, "Guess we'll have to wait till tomorrow for introductions, at least of you to the team. Bunk room is—"
"Down the corridor, take the left at the end, four doors down."
He chuckles, "Guess it shouldn't surprise me that you know that already. I'll see you in the morning."
She nods, and heads off down the hallway. Sophie tugs out her mobile when she arrives in the room. She sends a quick silent thank you to Ianto for always being prepared, and having the beds made up. She scrolls through her contacts again, trying to see if she recognizes any of the names on the list. She reads each name individually, and knows that none of the numbers are her friends. She tosses the phone onto the bed, and starts to pace across the room. Sophie knows she doesn't have her backpack, which means no sonic screwdriver, so she can't even scan herself.
Flopping down on the bed, she sighs deeply, and stares up at the ceiling, her brain running at a mile a minute. Sophie lays on the bed, staring blankly at the ceiling for hours, wanting more than anything that the memories of the Year to leave her alone. But everything that the Master forced her to do is flooding back in all at once, and she can't stop it. She doesn't realize when the tears start, but when they start to come as floods out of her eyes, she curls into a ball, and hugs herself.
