S4E11 Dick Solomon of the Indiana Solomons

An unexpected invitation from 'Aunt Florence' arrives, asking 'Richard Solomon' to join a family reunion in Indiana. Realizing it’s a mix-up, Dick decides to call Florence to clarify. However, he learns that Richard is so distant from his family that they wouldn’t even recognize him. Inspired by the idea of connecting with his roots, he chooses to attend the reunion. Once he gets there, it becomes evident that the rift between Richard and his family stems from a long-standing feud that remains unresolved.
