Author's Notes:
Written for Challenge 475: Cord at dw100.

Summary: The Doctor's fascination with humans ties him to earth.

It was as if an invisible cord tied the Doctor to earth; he’d invested so much time and effort in the people and their world, they had such potential, how could he simply sit back and let them get on with business by themselves?

He couldn’t interfere too much, there were things they needed to work out on their own, and some events were fixed points; they couldn’t be altered even if he wanted to, but still…

A gentle nudge here and there, a word in the right ear, just to keep humanity on the right track; no harm there!
