Trillian couldn't sleep. She sat on a couch and stared at a small cage which contained her last and only links with Earth — two white mice that she had insisted Zaphod let her bring. She had expected not to see the planet again, but she was disturbed by her negative reaction to the planet's destruction. It seemed remote and unreal and she could find no thoughts to think about it. She watched the mice scurrying round the cage and running furiously in their little plastic treadwheels till they occupied her whole attention. Suddenly she shook herself and went back to the bridge to watch over the tiny flashing lights and figures that charted the ship's progress through the void. She wished she knew what it was she was trying not to think about.
Zaphod couldn't sleep. He also wished he knew what it was that he wouldn't let himself think about. For as long as he could remember he'd suffered from a vague nagging feeling of being not all there. Most of the time he was able to put this thought aside and not worry about it, but it had been re-awakened by the sudden inexplicable arrival of Ford Prefect and Arthur Dent. Somehow it seemed to conform to a pattern that he couldn't see.
Ford couldn't sleep. He was too excited about being back on the road again. Fifteen years of virtual imprisonment were over, just as he was finally beginning to give up hope. Knocking about with Zaphod for a bit promised to be a lot of fun, though there seemed to be something faintly odd about his semi-cousin that he couldn't put his finger on. The fact that he had become President of the Galaxy was frankly astonishing, as was the manner of his leaving the post. Was there a reason behind it? There would be no point in asking Zaphod, he never appeared to have a reason for anything he did at all: he had turned unfathomably into an art form. He attacked everything in life with a mixture of extraordinary genius and naive incompetence and it was often difficult to tell which was which.
Arthur slept: he was terribly tired.
There was a tap at Zaphod's door. It slid open.
"Zaphod ...?"
"Yeah?"
"I think we just found what you came to look for."
"Hey, yeah?"
