One thing I'm liking about Mad Men is that it isn't obvious. Some series and movies can't help but to state its theme like the audience is made of five year old boys and constantly preach both in dialogue and action while thinking it's delivering a honest message. Mad Men is literature in the small screen, the audiovisual equivalent of a good slow burner novel. This episode main motiff is secrets. There is a pitch to a bank about the idea of men opening up discretionary accounts that their families won't know about, and after that Don goes visit his mistress, and after that Don goes see his half brother that even his family doesn't know about his existence, while he calls Don by another name - Dick. The scenes between Don and Adam are the spotlight of the episode. I'm liking Mad Man more each episode I watch. It's good that it forces me to think and pay attention to what it happens. As I said, there's too much obvious movies and series out there, so cheers to you, Mad Men. You can tell stories that doesn't appeal to exposition and it is all about reading between the lines,
