This is the very first chapter I came up with.
Did they really look like a couple?
Surely not!
They never held hands (well, except for when they were running), and they didn't touch more than necessary (at least, Donna didn't think so).
They didn't look overly affectionate with one another, and they—she knew that this was as sure a fact as that the Earth spun around the Sun—didn't speak grand declarations of love to each other.
She understood why someone could have been attracted to the Doctor, knew why Rose had been. With her it must have been obvious, but Donna could find no reason for there to be those same thoughts about her.
They were just friends, for God's sake.
And for someone's sake, she should stop thinking about it and go save the planet.
