One crucial detail about Roger that doesn't seem to have elicited much comment is that right at the beginning, Roger shows himself to be on the right side of the civil rights debate. That is important is that it tells us that his later resistance is not driven by racism but by his own harrowing experience. This is an important historical detail: you simply cannot relativize the horrific abuses committed by the Japanese in WW2 away. There really were bad guys in that war and there is no reasonable way to suggest that the bad guys were anybody but the Japanese and the Germans.
I also think it is very important that Don's subterfuge is used to shame the Japanese. When he tells Peggy, Joan and Pete about it, heys says. "Don't worry about the rules," forcefully and then adds, sotto voce. "For now". The whole thing is a ruse and not tied to anyone's genuine guilt. What Don does to his rival Shaw in fooling him into bankrupting himself on a commercial is good old-fashioned American flim flam. What he does to the Japanese is to shame them according to their rules.
It's a nice touch, BTW, that he writes them a personal cheque rather than a cheque against the business.
Don seems to be the only one who understands this. Except, maybe, for Roger. One of the reasons I keep bringing up the fight club interpretation is that these two never seem so deeply opposed as they might appear on the surface.
I know I said, it wasn't worth listing all the deceptions but there is one more I think worth noting. Don takes Bethany on a "date" that is really just an excuse to go to a Japanese restaurant and see the culture. He's using her and that should leave a bitter after taste in the mouths of those gloating about these young, feminist women getting the upper hand on Don. Apparently that is only for a while.
Assuming we get to see Bethany again, I wonder how she will respond to being ignored. She was clearly chafing at the lack of romance last night. Will she offer sex in attempt to get romance or would that be too depressingly like real life?
Update: One more, Dr. Edna quickly figures out that Sally is probably just fine and the only real problem is her whacked out mother. So she pulls a trick on Betty and asks here to meet regularly with her as a way of furthering her ability to help Sally when she obviously intends to try and help Betty.
