When "Mad Men" returns on Sunday to offer its final seven episodes, there's far more business than pleasure to tie up for the employees of Sterling Cooper & Partners.

On a series that has always been keen on selling happy endings over actually providing them for its ad-makers, how will fate treat the likes of Don Draper (Jon Hamm), Peggy Olsen (Elizabeth Moss), Roger Sterling (John Slattery) and Joan Harris (Christina Hendricks)?

TheWrap looks at back at where we left the the characters, their business and all future prospects before the show debuts on Sunday at 10 p.m. on AMC.

Beginning with:

1. The Dissolution of Don and Megan
The cable network chose to split Matthew Weiner's final 14 episodes in half, airing the first batch last spring. As of Part 1's finale, we learned that the second Mrs. Draper (Jessica Pare's Megan) was finito.

While a touching phone call with Don implied their looming divorce would not be contentious, and that Megan intended to support herself financially, these two don't give us a Chris-and-Gwyneth vibe. Megan made no headway in booking commercial or TV roles when she moved to Hollywood — in fact, Don was dispatched by her agent to help calm his bride's insecurities in the face of constant rejection. So, will she really walk off into the series' sunset an independent woman?

2. Business Affairs
Palace intrigue often pulls focus from the business getting done at Sterling Cooper & Partners. When we last saw him, Roger Sterling had successfully negotiated the absorption of SC&P into McCan-Erickson, as a free standing agency with Sterling installed as president.

Draper and Ted Chaough maintained Creative Director positions and the company counted all of its original partners (minus the late Bert Cooper): Don Draper, Joan Harris, Ted Chaough, Roger Sterling, Pete Campbell and Jim Cutler.

Lou Avery is gone. No more cardigans. Don has, in essence, been fully reinstated to the position he so forcefully squandered then toiled to gain back.

Joan had finally won the financial reward her 5 percent stake in the company promised her (at the cost of her body, easily one of the most controversial storylines ever on the series). On the last finale, the show estimated her payout being $1.5 million in 1969 — which is about $9.5 million today, adjusted for inflation.

Dawn Chambers (Teyonah Parris) is the administrative queen of the office. Long live Dawn Chambers and her key to the Post-Its.

3. The Francis Family
While the show reportedly jumps ahead a few years (which is not uncommon in between seasons of "Mad Men"), the last we knew of Henry Francis' (Christopher Stanley) upward mobility was his eyeing a shot at Attorney General, as extensively bragged about by his wife Betty (January Jones). We'd expect him in such a position if not higher on the food chain, with his wife wording over whatever suburban enclave she casts her eyes upon.

4. We Need to Talk About Sally
Ever the product of her narcissistic parents, Sally Draper (Kiernan Shipka) grows and regresses in equal measure. Take the satisfaction of last year's Valentine's Day episode, wherein her father Don owns up to a byzantine system of lies. She still tells him "I love you," and she means it. That same season sees Sally horse around with golf clubs in a boarding school fight and break her nose, enraging mother Betty whose empire is built on her own face. One step forward, two steps back. Where will we find her?

5. Middle Management

Fall the fantastic characters caught between Draper drama, bedrooms and boardrooms:

Peggy Olsen (Moss) won a major piece of business in Burger Chef, but is lonelier than ever at the top. Even the young boy tenant she kept as a TV-watching companion moved to Newark. Will she go Ginsberg, nipple-slicing crazy or finally engage in a social life? Pete Campbell (Vincent Kartheiser) ended a very California affair with a very blonde California real estate agent. Then, his lingering hopes of a reconciliation with estranged wife Trudy (Allison Brie) were dealt a final, crushing blow. His eternal dissatisfaction in the rewards of good business may finally catch up to those in his personal dealings. Harry Crane (Rich Sommer) was almost named partner before Sterling pulled off the McCan-Erickson deal, once again proving the agency's total disinterest in what Harry brings to the table, despite the importance and forward thinking of the media department he oversees. Will he finally find the chutzpah to leave SC&P?
