A very solid season starter. In this starter, everyone but Bill is putting on a facade to prove that they are not damaged from last season's fallout.
Virginia is desperately trying to prove that is is every bit as capable as Bill is, but I suspect that she doesn't believe that herself. For better or worse, she needs Bill as much as Bill needs her to be in her top form.
Libby is rightfully angry and bitter, but and completely engulfed in misery and unhappy. I hope she finds herself, much like Margaret Scully. But I am afraid she's chasing after Betty Draper/Francis of Mad Men.
As for Bill, it is fascinating to see his transformation from a control freak in season 1 to a resigned... well, hobo.
