'Mad Men' Season 7 Spoilers: Episode 13 Recap - Betty, Cancer-Stricken, Knows 'When to Move On'

"Mad Men" fans were shown scenes from the future lives of the characters they love when the AMC drama series aired the penultimate episode of its Season 7, entitled "The Milk and Honey Route," on May 10.

Betty is terminally sick, but won't get treatment. Pete gets a lucrative career opportunity with Lear Jets, and he gets back together with Trudy. Don is still in Wyoming, spending time with war vets, spilling his secret and giving second chances.

With all the cigarette smoking the series had shown over the years, it was inevitable that at least someone would contract lung cancer. Everyone thought it would be Don. But it turned out to be Betty, who refused to get treatment, to the exasperation of her husband, Henry. Henry sought out Sally, and although she also had a hard time processing the news, she had to comfort Henry while taking care of her toddler brother Gene.

Sally confronted her mother on the reason Betty was refusing treatment, accusing her mother of loving the tragedy. Betty was calm when she said, "I don't want you to think I'm a quitter. I fought for plenty in my life and that's how I know when it's over. It's not a weakness. It's been a gift to me to know when to move on."

Betty gave Sally a letter to be read upon her death, but Sally read it immediately anyway. In her letter, Betty wrote where she wants to be laid to rest, telling Sally to remind the funeral home how she likes to wear her hair, and the dress she wants to be buried in.

Betty said, "I always worried about you because you marched to the beat of your own drum. But now I know that's good. I know your life will be an adventure."

Pete got his happy ending by working out a lucrative job offer from Duck Phillips' new client, Lear Jets, and by getting back together with Trudy, saying, "I've never loved anyone else. Ever."

Don was still in an adventure of his own. His car broke down in Oklahoma and he had to stay in a motel as he waited for his car to get fixed. He got an invitation to a Veterans of Foreign Wars gathering. There was tension as fellow Korean War veterans surround him. Don's story came out in a drunken story, and the others responded by saying, "You just do what you have to do to come home."

However, believing he stole money from them, the vets beat him in the middle of the night with a phone book. Don knew who the real culprit was, the motel's bellboy. Don advised the bellboy to return the money, saying that if he kept it, he would become someone else. Don offered him a ride out of town, and ultimately, handed over the keys to his car, while he was left at the side of the road with his things.
