After an interminable 17-month hiatus, AMC's Mad Men is finally back! Because it's been so long since we last visited the offices of Sterling Cooper Draper Pryce, we'll be playing catch-up with the show's most important story lines all week before the show's two-hour premiere on Sunday, March 25 at 9/8c.

What will Joan and Roger's relationship look like?
We're sure the pair can keep their love child a secret. But the bigger question will be how Roger reacts to having been lied to about the abortion. If it means more fiery scenes between the two, bring it on!

Will Greg make it back alive from Vietnam?
The show's already placed so much dramatic emphasis on Joan's fear about Greg being in the middle of the war that it wouldn't surprise us at all if he stepped on a landmine. Nor would it really bother us. (Sorry, we still haven't forgiven him for that awful office rape in Season 2.)

Mad Men premieres Sunday at 9/8c on AMC.
