Visual echo: Rita's purse contains the bloody money, Diane's purse contains the hit money
The money in Diane's dream is exaggerated; there are stacks of it in Rita's purse, at least 4 packets, but when Diane is in Winkie's with the hit man, there isn't nearly so much as that.
Or does it clues us into Diane having spend already most of the stack?
In reality, the money that's used to pay the
hitman is the inheritance
Diane received from Aunt Ruth. In the dream, Diane hides the money "under her
hat" (literally she puts it in that box under a hat). As long as the money
is hidden, it can't be used to kill Camilla...so she's still alive. It's just
another way Diane is trying to prevent Rita/Camilla from being murdered. -
Popular reviews such as on
have it that Diane's purse contains $50,000, which however is pure assumption as
exact amount is never revealed in the movie. According to the Pilot script
Rita's purse is filled with $125,000 cash in hundred dollar bills.
