"What, broken, sticking out like a sore thumb and unable to change?"
She joked with a smirk and light laugh, shaking her head. It felt so wonderful to be talking to him again, to another Time Lord at all. Someone who understood what she was saying, who knew about TARDIS's and time travel and the vortex and Gallifrey. Someone she didn't have to act like a human with. As much as she had enjoyed her last few months teaching some of the brightest young adults of Earth, it was exhausting having to constantly lie about and hide who and what she really was. It made her want to scream sometimes, she shepherd the entire class into her TARDIS and show them what the universe really held. She supposed she partly understood now why the Doctor rarely travelled alone.
"You'd never settle anywhere. You've been running since the day you stole that ship," she commented, holding his eyes, "and don't see you stopping after 900 years. It'd be one hell of a habit to break now."
She rolled her eyes as he mentioned losing the Zero Room. It was just typical of him to manage to lose one of the most important rooms in a TARDIS. He was so carefree about things she would have been desperate to fix, and she'd never quite been able to understand it. But then, that was exactly what she'd loved about being around him. Though she'd come close to death and regeneration more times than she liked to remember, she'd also had some amazing times.
She packed up her things quickly and followed the Doctor to his ship as she had done many times before, a slight, barely noticeable spring in her step. She caught a few curious looks from her students, obviously wondering who the stranger was, and wondered what they were thinking as she left the campus grounds. She could see something was bothering her old partner, but any questions were quelled as she saw the dark blue box stood beneath a willow tree. Her eyes widened in excitement, and she couldn't help but break into a run, placing a loving hand on the door of the police box and pressing her cheek against it as if embracing it. She could hear the familiar hum of the engine, and feel the ship reacting to a familiar, yet at the same time strange touch, and laughed.
"Hello there old girl," she said, patting the wooden frames, "did you miss me?"
She turned to glance back at the ship's owner, like a child who's just seen all their presents under the tree. Without a key, she was going no further without his permission. Though the TARDIS knew her, it would do nothing without his permission, like her own.
"Going to show me what you've done with her, then, Doctor?"
