"What are you doing?" River asked as the Doctor came back with Jack. She had been talking to Chloe whilst the Doctor wanted Jack's help with something. The universe knew what he was up to, and was probably laughing because of it. As she did with Jack and the Doctor, Chloe intrigued River. They had been swapping questions and answers with each other, slowly piecing on another together, and River began to like the girl. After all, they were sort of family, in a way. Not by blood, but by species. That made her feel even closer to Chloe, but everything seemed so special about her, so unique.
"I don't know what he's up to," Jack replied as he leaned on the railings next to her, "But I'm guessing it's not harmful considering he wanted me to buy Mentos and Coca Cola."
River laughed as Chloe skipped over to the Doctor, who was fidgeting with a plastic case.
"Why do you think he's doing it?" Jack asked as he watched the pair.
"The Doctor is like a little child at times, especially in this incarnation, and from what I've gathered, Chloe's not had much of a childhood, so together..."
"You get Mentos and Coca Cola," Jack added, "Literally."
"Yes."
Jack chuckled, "Well, at least this is going to be fun!"
River laughed and looked on as the Doctor triumphantly smiled at her and skipped over towards the console. "I'm supposing we're going somewhere," she pointed out.
"Yes!" The Doctor replied, spinning round to her and giving her another smile, "What else should we do? There's no point in staying in here for so long when there are galaxies to explore!"
River laughed again, "Where?"
"There's an uninhabited planet – a neutral planet – where there are fields the size of continents. Anyone can go there, but if you try to claim it, then you'll have the Shadow Proclamation on your back!" The Doctor explained gleefully.
"I'm not even going to ask how you know that!" Jack exclaimed.
The Doctor just smiled and spun round again. "Chloe!" He called.
In reply, Chloe poked her head out of hiding from behind the centre column of the TARDIS, an expectant expression on her face.
"Press that button over there, please," the Doctor said, pointing to one of the many pieces on the console.
"Got it," Chloe said and pressed the button he had directed her to. He continued to direct her to us the controls of the console.
"Doctor, what are you doing?" Jack asked as Chloe worked around the console.
"Teaching her to fly the TARDIS," the Doctor replied casually before continuing to teach Chloe.
"OK, why?"
"She's the child of the TARDIS. Well, I say the TARDIS but I really mean a TARDIS because the TARDIS she was...created in wasn't this one."
"There's another TARDIS?"
"No! Don't be silly! I gave the metacrisis a piece of the TARDIS so he could grow his own. He obviously did and travelled in it with Rose, during which
they must have...created Chloe. So, she was created in a TARDIS in a parallel universe but not exactly this TARDIS."
It took Jack a moment to think about what the Time Lord just said. "Right...So why are you teaching her?"
"Well, she's going to need to know how to fly it one day. Why not let it be today?"
"I'm still here, by the way," Chloe pointed out.
"Sorry," Jack and the Doctor said in unison.
Chloe looked at River and both of them chuckled.
"Right!" The Doctor said, clapping his hands together, "Let's get going! Chloe, pull that lever!"
Chloe pulled the lever he had pointed her to, and the TARDIS jolted, zooming into the time vortex.
