The creature was still feeding. The Doctor looked over to it, then back to the man at its feet. Alan was just a man. He was just a silly little human, probably didn't even know a millionths of the things the Doctor knew. But there he was, pushing past something the Doctor ran from.

It wasn't the first time the Doctor envied him.

"You didn't have anything to be jealous about," the Doctor said. "On her birthday last year, I offered her a trip around the universe. She said she'd rather stay with Luke and you. Something about a picnic, I wasn't really paying attention."

The Doctor had paid attention. He wanted to know what it was that was so much better than spending time with him. He was, after all, the Time Lord and all that rubbish. But Sarah wanted to stay at home. She was so excited about so many little things. She was so happy.
