Turtles, Splinter, and Ninjara head for home. The ship is met by a horrendous storm. The ship is capsized and a temporal overlapping is triggered linking them to an event that happened exactly 500 years ago, the voyage of Christopher Columbus. An Earth Spirit, the Other, teaches Donatello about the fiasco for the native americans that was the arrival of Columbus.
The next morning, Donatello awakes and our heroes continue their trek to New York City.
