BILL OF HEALTH It was a big milestone for Thomas, as Dr. Maria announced that he was fully healed from his appendectomy and cleared to resume his piloting duties. He and Remora celebrated, and then she returned to the water tanks in her Mermaid Classic form. (And yes, Samantha returned the dodos to their normal shapes as well. Sigh.) Maria and Don still haven't been given enough credit for the surgery's successful outcome. As operating surgeon and nurse they were entirely their own, 100 million miles from backup. In the five years he played in the NBA Don never faced this level of pressure. Together they saved Thomas's life. So we sail on, now just weeks away from Mars. Maria's next task will be to deliver Samantha's baby, either before or after landing.
