   Summary

   Traveling on the Stan of War II gets them sent to weird places and sidetracked with different tasks, on one occasion Stan swipes a talisman from a weird crypt they visit. Within the span of a week, both of their concerns grow; Ford's concerned his twin is sicker than he's letting on, Stan's concerned with the weird stuff happening to his body. Ford convinces Stan to tell him what's going on with him, then they're facing a possible upcoming storm and Stan has to come to terms with going into labor.
