Okay now I can't believe nobody saw this. When Edward Norton is downstairs with Marla getting food from the Meals on Wheels truck (just before checking her for Breast Canser) she ask what happen to his hand. This is after Brad did the lye thing to his hand. Later in the movie before Tyler (Brad Pitt) started his army thing, Marla and Edward are yelling and she says, "Oh my god! What happend to your hand?!" Didn't she already see it?!
