***SPOILERS AHEAD***

Almost 11 months after “Mad Men” paused it’s final season, the show finally returned last night with the first of its final episodes.

After Don Draper (Jon Hamm) and his actress-wife Megan (Jessica Paré) decided to end their marriage in the last episode of the first part of season seven, Sunday's premiere had Draper back to his skirt-chasing ways.

One interesting storyline through the episode is Don’s reaction to the death of Rachel Menken (Maggie Siff), an old fling of Don’s from back in season 1.

But who is this past character who is suddenly addressed in the new episode?

On Sunday, we saw her appear wearing nothing but a long fur coat in a dream Don has about casting models models for an ad.

When Don later meets a waitress at a diner (Elizabeth Reaser of "Twilight" fame), he ends up having sex with her because she reminds him of Rachel.

Through more business meetings, the two began to connect, which inevitably leads to them beginning to sleep together when Don was still married to Betty (January Jones).

And thanks to Rachel, we finally got our first glimpse into Don’s past. In an episode towards the end of the first season, Don reveals to her after making love that his mother was a prostitute and that his father was a drunk.
