From the season 6 final scene

The final season of Mad Men will kick off on April 5th, with just seven episodes left, and then darkness forever. Showrunner Matthew Weiner has said in the past that he always has a last visual image in mind when writing a new season, so those final shots are important ones every season. Below, a quick look back at how he's ended every other season...

Season 1: The Wheel
Don comes home to think he'll find his family in time to go away for Thanksgiving with them, but they've already left, leaving him alone. As Don sits alone, the camera moves away from him as "Don't Think Twice, It's All Right" by Bob Dylan plays.

Season 2: Meditations In An Emergency
Betty sits down with Don at their kitchen table and tells him she's pregnant. The camera moves back from them as they stare at each other, not smiling.

Season 3: Shut The Door. Have A Seat.
Betty and Don decide to get a divorce, and as Betty flies away with her new husband Henry, Don is seen in Manhattan, getting dropped off in a cab at his new apartment. As he walks up the stoop, "Shahadaroba" by Roy Orbison is playing. Some of the lyrics are: "Face the future and forget about the past... In the future you will find a love that lasts"

Season 4: Tomorrowland
After he has a parting drink with Betty in their old home, Don is back in Manhattan and awake in bed with Megan, who is sleeping. He looks out the window and "I Got You Babe" starts to play.

Season 5: The Phantom
Don has just left Megan at a commercial shoot he landed for her, and is sitting at a bar alone. Weiner says: "I envisioned.. that Don would be in that bar. That was the last image, always, that someone would come up and say, 'Are you alone?' And we wouldn’t know what he answers." Nancy Sinatra singing the theme to "You Only Live Twice" (a 1967 James Bond film) is playing.

Season 6: In Care Of
Don pulls up to a run-down home. HIs kids are with him in his car, saying, "This is a bad neighborhood." They all get out and stand in front of the house, and Don tells them, "This is where I grew up." Judy Collins' "Both Sides Now" begins to play.

Season 7: Waterloo
As Roger Sterling is making an announcement to the staff regarding Burt Cooper's death, Don heads downstairs, where he hears, "Don my boy..." Cooper then busts out into a song and dance. Matthew Weiner said, "As for 'The Best Things in Life Are Free,' it is a very simple song with a very simple message: Life is bigger than business.”

The 2nd half of Season 7 will be it for the show, and Weiner knew how the series would end since 2011 (maybe longer). Back then he said, "It came to me in the middle of last season. I always felt like it would be the experience of human life. And human life has a destination. It doesn't mean Don's gonna die. What I'm looking for, and how I hope to end the show, is like... It's 2011. Don Draper would be 84 right now. I want to leave the show in a place where you have an idea of what it meant and how it's related to you."
