Homecoming

From Hulk Wiki

On Thanksgiving, David returns to his home in Colorado where he reunites with his sister and estranged father. There, he must resolve past conflicts with his father while working to save his family's farm from a devastating plague and an unscrupulous developer. Comments: One of the best episodes of the third season, this is a must-see episode. Despite the interesting premise, David's father and sister are never seen in the series again. The late John Marley ("The Godfather") guest stars as David's father along with Diana Muldaur ("LA Law", "Star Trek: The Next Generation") as David's sister.
