Fans of Mad Men have been captivated by recent parallels between Megan Draper/Sharon Tate and suggestions that the character may be killed off.

Now, writer Margaret Lyons of New York Magazine's Vulture blog has a new theory about Megan's husband Don Draper, and it's also got a Roman Polanski connection.

Lyon's article, posted on Thursday, has the blunt title Don Draper Is Rosemary From Rosemary's Baby, and she starts by relating the scene from Sunday's episode where he and Megan go see the film in the theaters.

"Megan said it was scary. Don said it was disturbing," Lyons wrote.

"But neither of them noticed that they are living inside that movie every stinkin' day."

Lyons cites some characteristic similarities between the Drapers and their comrades and people from the book and movie. The Drapers live in a building on the other side of the park from the Dakota, and Rosemary's husband Guy is a struggling actor, as Megan had recently been herself. A new friend Rosemary made in the building later committed suicide, and the author compares that friend's death to that of Lane Pryce, who hanged himself in his office in the previous season's penultimate episode, Commissions and Fees.

Even a fight in the film over a dessert becomes reminiscent of a fight Don and Megan had at a Howard Johnson's over orange sherbet, from the season 5 episode Far Away Places.

Her final suggestion is related to Don's hallucinations in A Tale Of Two Cities and when Rosemary is drugged by her neighbors.

In that scene, "Don's the one in a panic, Don's the one who looks all wan and gross, Don's the one getting devilish trinkets from his neighbors," wrote Lyons, noting that his former mistress Sylvia once gave him a copy of Dante's Inferno.

"Don's the one who's gestating a monster," she continued.

Only, to Lyons, ultimately Don is really the monster.

"First, in Peggy's commercial pitch, Don plays the baby - waah, waah - and just as a reminder, the baby in Rosemary's Baby is the devil. Later, back in his office, Peggy is livid. 'You're a monster,' she tells him."

But while there may still be theories about what could happen, Mad Men creator and who runner Matthew Weiner assured fans last week what won't.

In a Los Angeles Times roundtable held last week, Weiner was uncharacteristically candid in discussing some of the recent rumors.

"I don't want to spoil anything for people, but after Lane..." Weiner mentioned the death of Lane Pryce from last season before stating, "It's just not part of the show. No one's going to die."

"Thank God!" exulted Jessica Paré, who plays Megan; it was her character who has seemed the mostly likely candidate.

However, Weiner did insist that the situation is always open to change: "This season," he stated. "I didn't say never!"

The season finale of Mad Men, In Care Of, airs on Sunday.

Watch the preview for Episode 13, In Care Of.
