When Did Megan Find Out About Dick Whitman?

Megan Whitman doesn't exactly have the same ring to it

Betty’s Season 3 confrontation with Don over his true identity is one of the show’s most devastating scenes. A housewife who believed she married into the ideal of the American dream discovers it has always been a nightmare.

Her husband is not who he says he is.

She married Dick Whitman, a child of poverty and suffering who clawed his way through fire and death into a new life.

The Draper’s marriage didn’t become a lie, it always had been.

Only three seasons in with six years of the 1960s left to go, there was no doubt that Don would get married again. The question was if Don would hide himself and build another marriage upon a lie.

Sometime between the end of Season 4 and the beginning of Season 5, Don Draper’s second (legally third) wife Megan is told the truth about his identity. She handles it well and speaks mockingly of Dick Whitman. Dick never was and never will be her husband. She is singing “Zou Bisou” on Don’s birthday and not Dick’s.

She puts Dick Whitman forever in the past in a way that Don can not.
