1) Kill some one. Works like a charm ;-)
2) Send the main characters back to November 1492 England. Why there? Why then? I have no idea, that's what you have to find out.
3) Have your main character start singing "99 bottles of pop on the wall", Keep repeating until you come up with something better.
4) Abandon your main characters and follow the story of the time traveling squirrels that live under the porch.
