The next morning, Ted accuses Don of “trying to poison my relationship” with Chevy by discussing the war. Ted asks, “Did you ever think about talking to me instead of our most important client?” In exchange for stopping “the war you’re waging on me,” Ted offers to contact a brigadier general in the Air National Guard. Ted tells Don to have Mitchell write a letter and cut his hair.
Don phones Arnold. Sylvia answers. Don tells her about the Air National Guard plan. She cries and says, “You were good to me. Better than I was to you.”
In his office, Pete tells Bob that Manolo is a rapist. Bob says, Manolo is gay and Dot loves Manolo because he takes care of her. “When there’s true love, does it matter who it is?” Bob asks.
