The Doctor and her companions are fleeing on a big sailing ship, the Master hot on their trail. It’s a spectacular journey, the ship is so fast, it flies, it jumps, it skids beautifully on giant water slides.
They reach the far corner of the map, then turn around and sail to the other end. The Master finally catches up with them, he sighs, he moans, he monologues, and then he lets the Doctor go: after all, he can’t live without his best enemy.
