Betty and the Box: Finally, Betty gets into that locked door in Don's dresser, thanks to a set of loose keys in the dryer. It says something that all Betty wants to do is see past Don's hard shell to the truth that is lying underneath, and as soon as he slips up even once and leaves the keys to the drawer in his bathrobe, Betty knows exactly what the incriminating keys are for. But can she handle the look into Don's heart of darkness? Probably not.

Earlier in the night, when the phone rings and there is no one on the other line, Sally gets all upset. "My goodness, Sally Draper, try not to take everything so personally," Betty snaps at her. Well, Betty is the last person who should be trying to teach people this lesson. Not only does she take it personally and think that the call is her spurned would-be lover Henry, but she also takes it personally when she opens the box. She's not shocked by the pictures of Don as a boy but named Dick, the deed to a house in California, or his purloined dog tags, she is shocked that he was married before. The one thing that Betty really cares about is the one thing that effects her. So like Betty.

Of course, Betty sees this as a huge betrayal—and really, keeping all those things away from her truly is—but Don sees it as a way to survive. His new identity catapulted him up from his hillbilly roots to the WASPy station that Betty so much enjoys. And of course, she sees her Don as having gotten a divorce and never telling her, when it was the old, dead Don who was married to Anna, and not the man who is currently cheating on her with some psycho teacher.

And as Betty waits up for her man to come home so that she can spring the trap on him, he doesn't take the bait, because he's sniffing around at some prey of his own above a garage across town. When Don doesn't return home, Betty puts the box back into the drawer, locks it and returns the keys. She tries to lay into Don the next day, but her sadness gets the best of her, and she sinks further into her hole of unhappiness. She is hiding everything away both literally and figuratively. It's fitting then that Betty has looked the best she ever has—an ice blue gown for an ice princess—for the Sterling Cooper anniversary party that night, because it seems clear Don is only interested in her as a facade, something to show off for his advertising buddies. Who cares what lies below the surface when the surface is so beautiful.

But something is brewing with Betty. She continues to reach out to Henry, keeping the lines of communication open, even if it's to tell him not to call. And she's reading The Group, a satire of upper-class life by Mary McCarthy (yes, published in 1963), that features a heroine who gets a divorce. Hmm...

But the final scene of her clapping half-heartedly while Don receives his award is surely a sign that more is coming. Knowing Betty she is going to let the information about Don stew inside for a bit before acting out childishly and without thinking and doing something disastrous. Let's hope it involves setting her ugly fainting couch of desire aflame.
