For those of you who didn't watch last night's Season 5 finale of Mad Men, Episode 5.13: The Phantom, be warned because there are heavy spoilers within this story. AMC released a behind-the-scenes video from the episode, featuring creator Matthew Weiner revealing new insights into the finale, including the possible revelation that Jessica Paré's Megan Draper may be gone next season. Take a look at this extended video, and read on for more information.

The end of this episode features Megan finally getting work as an actress, albeit in a commercial for one of her husband's clients, Butler Shoes. One of the final moments of the season could be a clue that the Draper's are heading in different directions, according to Matthew Weiner.

"We see her on the [commercial] set and we realize that she's gone."

He also adds that Jon Hamm's Don, "knows that if he gives Megan what she wants, she could possibly leave him." Is Don heading for his second (well, technically, third) divorce next season? We'll have to wait until next year to find out for certain.
