He thought back to Jack's question about Turlough. He'd purposefully avoided answering, but shook his head. he should answer. There was no reason not to. "He left, after a while. Went back to his home world and his family. I don't think I expected to miss him as much as I did."

Then it had been himself, Peri and Erimem. And then, just himself and Peri. Until he left Peri on a strange world with no one to watch over her but herself.

"I'm really rubbish at this whole 'taking care of my companions' thing, I think," he muttered aloud.
