"Patti's Dad Dilemma" is the fifty-sixth episode of Doug.
Patti worries that Chad is dating Edwina, so she does everything, including eating at Chez Honque to find out. Patti discovers Chad is dating someone; but it's not Edwina, it's Ms. Krystal. When she has dinner at the Mayonnaise's, Patti feels she is trying to replace her mother and starts to cry her eyes out when she snaps at Ms. Krystal. She then sees her mom's grave and is comforted by her dad. After a heart-to-heart chat, Patti learns to accept that Chad will always love her and even though he loves Ms. Krystal too, her mother will never be truly replaced.
