Mad Men Refresher Course: Who Is the Father of Joan's Baby?

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.

Mad Men refresher course: What's up with Don's love life?

Up next: Who is the father of Joan's baby?WHERE WE LEFT OFF
With her ex-surgeon hubby Greg shipped off to basic training and later Vietnam, Joan (Christina Hendricks) did her best to resist the repeated come-ons of former lover and colleague Roger Sterling (John Slattery). But after weeks of fighting off his advances, Joanie finally agreed to an innocent dinner, during which the two reminisced over cherry cheesecake. Roger groused about being unable to put a chapter about Joan in his memoirs -- "Every time I think back, all the good stuff was with you," he said — and then on the walk home, the pair was mugged.They escaped the incident relatively unscathed, but thanks perhaps to a mixture of adrenaline and old emotions, the pair got biz-ay in a dark alley. Roger hoped to start things up again — especially after losing Lucky Strike, Sterling Cooper Draper Pryce's biggest client — and again Joan resisted. "I'm not sorry, but I'm married. And so are you," she said.

But then Joanie turned up pregnant. She convinced Roger he was the father and he promptly arranged for her to have an abortion. Joan didn't go through with the procedure, but told Roger she did. Then she called Greg in Vietnam to tell him he's going to be a father. (He must not be any better at math than he is at cutting people open.)
BURNING QUESTONS (AND OUR BEST GUESSES)
Will Joan carry the baby to term?
Although Mad Men is often bleak, we don't see the show breaking Joan's heart that way. We fully expect to see a baby at some point this season, if for no other reason than the built-in drama of showing Joan try to balance being a single mother with her workload.If a baby is born, will Roger know it's his?
He has to, right? After all, he knew Joan was preggers last season, and the likelihood of her getting knocked up again so soon after an abortion is highly unlikely.

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.)
