In "Mad Men"'s beautifully written pilot, Don wakes up with Midge, his cool, modern Village mistress. It's unclear how long they've been involved, but they move around each other as if they're very well-acquainted. Even though Midge ends up as a heroin addict, I rank this one relatively high in emotional healthiness because Midge seems like she can take care of her self. She expects very little from Don: she knows he's married, she knows he sleeps with other women besides her, and she doesn't really care. She has her own life and career, and doesn't need Don for fulfillment. She's very much in the moment with Don, and Don, in turn, seems to be himself with Midge in a way that he is not able to with others.
