But the glitch that gave us a future look at the series was quickly corrected, which leaves a very small number of us privy to the truly sublime episode. Thankfully we're in that group, and, as such, we figured we'd share some of the storyline from the episode. It does indeed include show spoilers, so you've been warned.
UPDATE: At the request of AMC, we have removed the screenshots.
Jane vs. Joan
The new Mrs. Sterling (as referred to by the ladies) and his former flame have a very delicious exchange at the Sterling Cooper office. The confrontation is nothing short of genius. Of course the heavy blows are thrown in couched and controlled dialogue, but their disdain for each other is more than palpable.
Pot in the Office
Despite the fact that most of Sterling Cooper is attending the garden party, Smitty, Paul Kinsey, and Peggy Olson find themselves working the weekend away on a Bacardi campaign, but with a little inspiration and assistance from an enlightening substance.
