What's the Teaser for Mad Men's Final Season Trying to Tell Us? (VIDEO)

It's finally here! On Thursday, AMC released the first teaser trailer for the final episodes of Mad Men's seventh season. Naturally, it doesn't reveal much—it's basically a video version of the promotional photos released on Wednesday—but here's what we think we know:

1. We're (probably) in the '70s

This is obvious from the fashions—particularly Megan's belly chain—as well as the fact that the teaser is set to Diana Ross's "Love Hangover," which was recorded in 1975 and released in 1976. With the first half of Season 7 concluding in July 1969, does this mean we have a time jump on our hands?

2. Peggy is still like, "Bye, Pete"

And who can blame her? Just look at that smarmy smirk (not to mention his dreadful haircut).

3. Sally is more wistful than ever

Has Sally accidentally found herself in a production of Cinderella? Good lord, that dress. But she's definitely inherited her mother's ability to stare, dead-eyed, into space. On a related note, when will AMC greenlight the spin-off Sally Draper's Misadventures at Miss Porter's?

4. It can't be stressed enough: Megan is wearing a belly chain

And it's pretty clear what Don thinks of it.

5. Joan continues to be the only one who can exert any kind of control over the ad guys

Poor Joan.

6. Roger is still a silver fox, despite his many, many transgressions

If there's a cure for this, we don't want it. But what's he grinning about?

Watch the full teaser below and then hit the comments with your own thoughts on what it's trying to say:

Mad Men returns Sunday, April 5 at 10pm on AMC.
