That's great, TIS. I'll take it easy on the spoilers until you catch up. But we did discover more about Peggy's character last night. Her development is the most fascinating, IMO. She has a psychological barrier of sorts, one that keeps her from displaying her true personality and emotions. But we don't really know what it is or what it stems from. IMO she's quite representative of a young working woman of those times, one who's trying to break free of the barriers enforced by social norms of the time. We haven't seen the true Peggy yet.
