They subsequently crash-land on a nearby planet, much to the chagrin of its Planet of the Apes-like population. With Lone Starr's debt to Pizza nullified by the gangster's untimely death, he returns Vespa to Roland and leaves, taking only enough money to cover his expenses. After a lunch break at a diner and a strange incident involving an alien and an astronaut similar to the events in Alien, Lone Starr finds a final message from Yogurt, informing him that the medallion necklace Lone Starr has been wearing reveals that he is a prince, and thus eligible to marry Vespa. He reaches Druidia in time to stop her wedding to Valium, announces his royal lineage, then marries Vespa.
