"Amy, show Belle where her room is," the Doctor says as they enter the TARDIS. Belle turns around.
"Where my-my—? I only wanted one trip," Belle stutters.
"Nope! You're staying. For a while, actually," the Doctor says. The TARDIS makes a noise. He looks up.
"Shut up," he tells the TARDIS. The TARDIS fights back. "Why don't you show her the way to her room with Amy?"
The TARDIS gives a cold breeze. Belle looks at the Doctor. "Does it not like me?"
"She," the Doctor corrects her. "She. Not 'it'."
Belle rolls her eyes. Amy starts to pull Belle and she leads her way through the TARDIS.
•••
Belle, Amy, and the Doctor just returned to the TARDIS after walking around a museum. The Doctor found something important. There had been someone who wrote him a message.
"Why are we doing this?" Belle asks as he's pulling levers and pushing buttons on the TARDIS console.
"Because someone on a spaceship twelve thousand years ago is trying to attract my attention. Let's see if we can get the security playback working."
•••
The Doctor tells Belle to open the doors to the TARDIS once it arrives where they need to be. She opens it, only to reveal a galaxy. And two people came after her, only by force. She screams as the Doctor runs towards her to catch the second person who came flying in. They all land on the floor with a thud.
"Thanks for the catch, Doctor!" a brunette says happily as she tries to get off him. The Doctor gives a nervous laugh. "Ave? River?"
"Who are you?" Belle asks as she sees River smiling at her.
"Hello sweetie," River says. "I guess we haven't met yet, have we?"
"That's Izzy?" Ave asks, pointing at Belle.
"Hey, Izzy's my nickname for her," Amy tells Ave.
"Follow that ship!" River tells the Doctor as he's up now. They rush towards the console. Ave helps Belle up and closes the TARDIS doors.
"I told River I didn't want to jump into outer space," she tells Belle. "Not without a spacesuit, but here we are."
She huffs, cleaning herself off. Belle cleans up after herself, too.
"Anything else you want to tell us, Doctor?" Belle asks as she goes over to Amy. "How do you know these women?"
"Long story–"
"They've gone into warp drive. We're losing them. Stay close," River interrupts them, making Belle frown. Ave reaches a hand out to shake Belle's. She's hesitant.
"I'm trying," The Doctor says as he keeps glancing over to Belle.
"Use the stabilizers," says River.
"There aren't any stabilizers," he states.
"The blue switches," River adds.
"I don't get involved in that. My father tells me I'm just like mother with that sort of stuff," Ave tells Belle as they let go shaking hands. "Ave Song. That's my sister, River Song."
"Isabelle," she tells her. "Isabelle Dunne."
The TARDIS suddenly stops rumbling. "See?" River says as everyone notices it.
"Yeah. Well, it's just boring now, isn't it? They're boring-ers. They're blue boring-ers," the Doctor says.
"Doctor, how come she can fly the TARDIS?" Amy asks. Ave watches Belle nod.
"How come she can?"
"You call that flying the TARDIS? Ha!" he says, moving around.
"Okay. I've mapped the probability vectors, done a fold-back on the temporal isometry, charted the ship to its destination, and parked us right alongside," says River. Belle has an odd feeling in her stomach. How is she so smart?
"Parked us? We haven't landed," the Doctor states.
"Of course we've landed. I just landed her," she tells them.
"But, it didn't make the noise."
"It doesn't have to," Ave states. He glares.
"What noise?" River asked.
"You know, the–"
He makes the odd noise.
"Honey, you're embarrassing yourself."
The Doctor frowns at Belle. Ave laughs.
"It's not supposed to make that noise. You leave the brakes on," River tells him.
"Yeah, well, it's a brilliant noise. I love that noise. Come along, Pond. Dunne. Let's have a look," the Doctor grabs Belle's hand. Her stomach flips. It stops when River interrupts him.
"No, wait. Environment checks."
"I knew he was forgetting something," Ave says as she follows River around.
"Oh yes, sorry. Quite right. Environment checks."
The Doctor opens the TARDIS door and looks out.
"Nice out," he says.
"I agree," Belle states after looking out. Ave smiles.
"We're somewhere in the Garn Belt. There's an atmosphere. Early indications suggest that–"
"We're on Alfava Metraxis, the seventh planet of the Dundra System. Oxygen rich atmosphere, all toxins in the soft band, eleven hour day and chances of rain later."
Belle's eyes widen at how good he got when explaining where they were. He winks at her.
"He thinks he's so hot when he does that," River rolls her eyes.
"How come you can fly the TARDIS? Ave, how come she can fly?"
"Two very special people taught her," Ave says, smiling.
"Oh, I had lessons from the very best," River winks towards Belle.
"Well, yeah," The Doctor says, kissing Belle's cheek.
"It's a shame you were busy that day, Doctor," River smirks. "Belle was fantastic."
"Should I correct her?" Belle whispers to the Doctor. The Doctor shakes his head. "You can try, but it won't work out."
"So... why did they land here?" Ave asks.
"They didn't land," the Doctor tells her. He squeezes Belle's hand.
"Sorry?" River asks.
"You should've checked the Home Box. It crashed."
River tells Ave to follow her. They leave.
"Explain who that is, and how did they do that museum thing?" Amy asks the Doctor.
"Like I said... It's a long story and I don't know most of it. Off we go–"
"What are you doing?" Belle asks.
"Leaving. She's got where she wants to go, let's go where we want to go. Ave can follow her anywhere," the Doctor told them as he ran back to the console.
"Are you basically running away?" Amy asks as they follow him.
"Yep," the Doctor tells her.
"Why?"
"Because she's the future. My future. Our future," he adds after looking at Belle. Belle frowns.
"Can you run away from that?"
"I can run away from anything I like. Time is not the boss of me."
"Just like you ran from me when I wanted to come back in the TARDIS when you dropped me off," Belle nudges him. He frowns.
"Hang on, is that a planet out there?" Amy asks.
"Yes, of course it's a planet."
"You promised me a planet. Five minutes?" Amy asks excitedly, grabbing Belle's hand.
"Okay, five minutes."
"Yes!"
"Well that's a lie," Belle murmurs, but is dragged by Amy. The Doctor follows after.
"But that's all, because I'm telling you now, that woman is not dragging me into anything with her sister."
