Dear Matthew Weiner,

You cannot leave all these plot threads dangling after next week. I will go mad (see what I did there?) if I have to wait until next summer to know whether we've seen the last of Sal or Joan. The strangled cry of frustration I let out after the preview for next week, which wasn't even the usual collection of cryptic sound bites but rather highlights from the season, will pale in comparison to the howl of rage brewing if we don't get some sort of indicator of whether this whole endeavor is ultimately character-driven or Sterling Cooper-driven. Have mercy.

P.S. Dear Janie Bryant, I am deeply in love with Trudy's blue dress for the wedding. Please try to make this a 2009 mass-market reality.
