From the Scrapbook Page One: First Flight
Authors Note: These are meant to be like a scrapbook of their travels, they're not all that's happened nor are they to be considered in order. They're just there to interject into the action of the main story.
She was as adventurous a companion anyone else the Doctor traveled with, though it wasn't easily deductable from Luna's spacey personality. It started with the one trip and then each trip built onto the last with time and space meaning little as they flitted between periods and planets.
On the oceanic satellite planet of Tectha, he taught her to fly the TARDIS. And not just travel through time and set destinations—but really fly. They glided over the planets liquid surface in the spinning police box, its blue, seemingly wooden exterior concealing it almost perfectly against the watery backdrop.
Luna took the TARDIS down over the water over her final pass over the planet. She lowered the ship carefully into the water, dragging it through the waves spraying water out in her wake. "I didn't think working this thing would be so simple," Luna said.
With her head down over the controls, her blonde hair framed her face. Huge radish shaped earrings dangled down just at the edge of her hair. She seemed at home on the helm of the TARDIS, something that he couldn't think he'd seen anyone else do.
The Doctor stared at her, shock playing across his pale features. He stepped nearer to the door and still looking back at her, opened it. The misty spray of water blew in through the TARDIS doors and Luna's white blonde hair whipped back on the wind. She laughed and the Doctor followed suit.
Craning his neck up, he watched the gray sky as they sped under it. "You're amazing Luna," the Doctor said. "I've never seen anyone take to a TARDIS like this."
"Thank you. Though you'd better close that door—water like this is a breeding ground for Nargles and we wouldn't want one of the bloody things jumping in here…" she said in a dreamy tone.
The Doctor noticed that she wasn't even paying attention to the controls. He shut the door. "Nargles—I'm guessing this is another of the creatures from The Quibbler," he laughed.
Luna nodded. "You can call me crazy if you want, it's just a sign of narrow-mindedness—"
He crossed the TARDIS and walked back to the center console where Luna was standing. "Nah, I think you shouldn't worry Luna. You're just as sane as I am," the Doctor took the controls from her and she stepped aside to let him have the helm.
Luna just stared up at him, beaming. "Where are we going next?" she asked.
"Not sure, I thought maybe we should just wing it," the Doctor said.
