S4, E15: When "Chaz" brings his new bride Tiffany home to meet the Powell family, they are convinced that there is something drastically wrong with him. Both Lillian and Walter are shocked by the news and concerned about the future of the marriage. Suspecting that there is something physically wrong with Charles, Buddy asks Nurse Bennet to examine him and then look for ways to extricate Charles from the marriage. Meanwhile, Tiffany pays Lillian a surprise visit to inform her that she wants out of the marriage because "Chaz" refuses to let her have a life of her own. Finally, Jamie and Sarah recall that just before Charles became "Chaz" they heard him say "ow" in the laundry room, supporting the theory that he might be suffering from temporary amnesia.
