A/N: In the wake of Journey's End, I think we're all in need of some serious fun. There are no spoilers, don't worry.
Secret Moments
The Doctor placed his hand on his hip and jutted it outward. He looked at his reflection in the full length mirror in front of him, and found himself very pleased with his appearance. He wrapped a finger around a strand of his long hair and smiled.
"Finally," he said.
Donna had been watching him from the doorway. She had seen him skipping in circles and flipping his hair over his shoulder like a teenage girl. She had watched him plait it down his shoulders and twist it into a bun.
Donna had been careful to not make any sound, though she wanted to burst with laughter. Her first reaction had been to mouth "wig?" in the exaggerated manner that was hers and then to stare open-mouthed for a few moments. However, Donna soon found herself overcome with an exhausting amount of pride. Her heart swelled to near epic proportions. She had never seen the Doctor smile so large or so sincerely. Nor had she ever seen him enjoy himself so much on his own. She felt quite privileged to see this occasion and rightly so.
Once the Doctor began to perform startling and accurate impressions of her, however, Donna rethought her silence.
"Oi, space man!" he said, moving his neck outward and opening his eyes a bit wider. He half-hoped his reflection wouldn't move with him and would instead play his part while he played Donna's.
"Oi, space man!" Donna echoed as she walked into the room.
The Doctor spun around quickly. The smile slackened, but reappeared larger than before. He stretched his arms out to either side. Red hair framed his face, disheveled from his fun and sticking out in every direction.
"Donna! I'm ginger!" he said.
Indeed he was. Finally.
