Betty is like the quintessential Hitchcock blonde - well-bred, icy and composed on the surface, but mostly hides her complexities and torn emotions. I think her detachment has mainly come from a deep-seated sense of things not being right with her marriage, which was finally proved correct. As she said herself after Don's admission, "At least I know I'm not crazy". I wish Series 3 would take up where this left off, but I suspect it will be a long leap again.
In the June (UK) issue of Harper's Bazaar there is a good interview with January Jones. She is on the cover and rather unrecognisable at first without the 50's makeup (which suits her so well).
JJ says about her character, " The truth is, I'm as confused by her as anyone. I don't judge Betty, but I often think, 'Really? That's the move she's making next?'" It says that she was "so vexed by Betty's infidelity that she marched to M.Weiner's office and argued a case for her character's morals. 'I was like, "Why would she do this?" He said it was possibly the end of the world - the Cuban Missile Crisis was going on - and there are no consequences for her actions."
Weiner says: "It always felt to me that in season one, Betty was a child, and season two became her adolescence. So, having been awakened to Don's infidelity, she needed to act out." He also says that he's not sure she has reached her breaking point, but he knows that her understanding of her marriage has changed. Oh dear, to me that spells more trouble in their marriage - I was really hoping there would be some light for them again.
It's interesting to note that JJ first went to audition for the role of Peggy.
There's mention that the third season production is under way. Nothing given away but there is a hint that the swinging 60's could have its effect. Personally, I could've enjoyed another whole series of the period they were last left in, and all the storylines delved into and sorted out. From that, then go into the liberated (yet destructive) later era. To see all the characters revelling in the frolics and temptations of that time will no doubt be as fascinating and as stylishly executed as we've already seen.
