Calvin's dad comes to visit D.C. He and Calvin have fun going to basketball games and going to see the Blue Angels fly. Because he and his grandma have been arguing a lot lately, Calvin makes the decision to live with his dad in Iceland, thinking it would be more fun than living in D.C. Pearl is sad about it but doesn't want to show it too much. Mary throws Calvin a going away party, and after he hears what nice things every one has to say about him, he realizes that he has more ""family"" than he thought and decides to stay in D.C.
