Of course there had to be heroes who stayed behind, the Doctor thought to himself. He probably would have done the same. He set the course on the TARDIS, and with the usual bumpy ride, he'd landed, materialized somewhere on the Sigrun. He peeked his head outside the door. "Well, this is dull. It looks like it'll rust before it explodes," he said casually. Shutting the door, he took out his guide, and composed a message to Rose, telling her where he was.
He figured he might as well go outside his ship and look around. The environment was stable enough, but the Doctor just hoped that Rose and the rest of the people he was going to take would be able to make it here safely.
