It was a perfect fairy tale world.
Donna thought about it all the time: Lee and what could have been.
He had been perfect, silent most of the time, a loving, devoted father and husband.
He made her feel special.
The Doctor had told he that Lee probably hadn't existed, but Donna held to the dream that he did, that he was waiting with their kids in her fantasy world.
With a sigh, Donna continued to walk with the Doctor, who was going a mile a minute and glancing at her every few seconds. She hadn't been paying attention.
Someone bumped into her.
"Oi! Watch it!"
"S-s-s-sorry."
A pause.
"Lee?"
Wide eyes stared at her.
"Donna?"
