'Mad Men': The Most Jaw-Dropping Moments of Season 5
Sally Draper (Kiernan Shipka) and Betty Francis (January Jones)
Betty Blabs About Anna
The first few seasons of the show, Don worked insanely hard to keep his Dick Whitman identity secret. Though he's opened up about it more as time went on, we still couldn't believe that Betty, in her jealous rage, would casually mention to her daughter that Don's actually had three wives. Thankfully, and much to Betty's chagrin, Megan and Don handled it well. That'll save Sally a few therapy sessions in the future.
