Notes: At the conclusion of the story, the Doctor navigates the off-course Mayflower in the direction of a truly habitable planet. The intent is that the crew should finally end their journey and begin life on the new world. Miss McCallista suggests they name a city planetside after the Doctor, in thanks for his assistance. He finds the idea of "Doctoropolis" a little awkward, but suggests they call the planet, "Arcadia" instead.
This may or may not be significant in light of the 2006 episode, "Doomsday" in which the Tenth Doctor speaks of the "fall of Arcadia" as being a part of the Time War he "might even come to grips with someday".
