Megan and Ginsberg really starred in this season. Megan's character is at times grown up and at times acts younger than Sally. It's hard to blame her based on her degenerate parents. Ginsberg is an odd duck, although he seems to be quite adept to the copywriter position. He achieves a modicum of success at the job, and SCD sans Price has had one of its most successful quarters. Pete has really started to turn into a Don Draper, cheating on his wife and despising time at home with his family.
I am excited for Season 6, this is my favorite show of all time.
