He could feel blood trickling out of his nose and his muscles ached; he was too old to be fighting like this. It was a bit ridiculous.

There was also the issue of him being followed, and the fact that she might find that she was better off without him.
He lifted his eyes to catch Bill's and shook his head slightly. "It's five days until the full moon," he said quietly. "It's going to get worse before it gets better."
