I.M. FOREMAN: You’ve never been a woman, have you?

DOCTOR: I’m not sure I’ve ever even been a man.

DOCTOR: I'm just a Time Lord dreaming he's a man. Or is it the other way around?

Sam was going to leave. Sam wanted to leave. Sam had decided to leave. Not one of those slow, creeping realisations, but an actual big, hard no-backing-out decision. She'd drawn the line in the sand, she'd made up her mind, she'd written it in her diary, and yes, the diary in question contained only one entry and that was it, but it was the thought that counted.

Going. Definitely going. Going going going.

Sarah had been banking on the dog being wrong about that. Who was going to be here? Friends of Sam's? Family even?

Surely not. The Doctor wouldn't have chosen her as a companion if she'd had family. Close family, anyway. He didn't work like that, did he? Even Batman only hired orphans as sidekicks.

'Hello Sarah Jane,' he said.

He wondered if Sarah looked surprised. It was hard to tell, since he could see only her knees from here. Her body was crouched down by his side.

'You,' she said. 'It's you, isn't it?'
