Prince Henry the Navigator was born in 1394 and was influential in exploring Africa's coast and trade routes to India. He was the third child of King John and became governor of the Order of Christ in 1420. Bobby knows an unusual family, the Beamonts, and gets stuck on a pink bible bus with some of the kids on the way to visit Mibs' father in the hospital. A man claiming to be a prince approaches them asking about Mibs' father but leaves after realizing he has the wrong person.
