Don naturally backed Sonny Liston against Cassius Clay that night in 1965. The way he liked Nixon over Kennedy a few seasons earlier. Don liked the guys who didn't brag.
And Peggy is Don's #2 now. Peggy gives don ideas and she tries to boast about it, but he shits on her. At least that's Peggy's take on it. But Don is adamant.
"That's the way it works. There are no credits on commercials."
"I give you money. You give me ideas."
When Peggy complains, "But you never say thank you!" Don is incredulous, "That's what the money is for!"
It is a pivotal night in Don's life. Not just because Don lost $100 on Liston, but because of the death of Anna Draper - and the close relationship he had with the woman who allowed him his name. And Don showed vulnerability for the very first time.
But at the end of the night (really the next day), a "spruced up" Don Draper realizes he has a stable relationship in his life. Despite the death of his great friend, his divorce, and his reckless drinking, he found someone to complete him, and not in the usual way Don relies on a woman.
And the constant shake-up of the pecking order on the Sterling Cooper Draper Pryce totem pole continues. At age 26 (Happy birthday!) Peggy Olson is in a tremendous position at her job. And she didn't know it until now.
