When Tim and Jill learn that Wilson is having his house appraised, they fear that their beloved neighbor is planning to move. Over a Thanksgiving dinner at Wilson's wildly appointed house, they find out that it's true - he's planning to pack up and move to the jungles of Ecuador. Tim and Jill can't imagine a life without Wilson, especially once Tim meets the frosty couple who're looking to buy his house. In the backyard the following day, Wilson confides in Tim that he's moving to Ecuador because that's where he first met his late wife Katherine, and that he hopes to feel closer to her by returning there. Tim quotes Wilson some Mario Andretti that convinces him that the best way to retain that connection is by staying where he is and keeping her memory alive by sharing it with the people around him. Meanwhile, Tim tries to dispose of a dead, rotted rat in his walls.
