A Streetcar Named Marge - S4-E2
Continuity mistake: As Marge is about to leave for her first audition, she walks across the room and she is wearing white slip-on shoes. Then her and Homer talk for a bit, then when it cuts to a wider shot after they talk, she now has her red flat-heels on. (00:03:30 - 00:04:00)
Chosen answer: I believe the post is refering to when Ben Kingsley's wife is yelling at him after the cop first threatens them with deportation. But his wife calls him a coward, not a traitor, and there is no one in the scene except for the 3 family members (I've gone through the scene several times in slow motion).
