The Suitcase was, like, my own personal wish-fulfilment episode. It was everything I wanted to see but never thought I'd get on that show.

It's amazing seeing such a grown up woman on TV who's still young and fun.

That's a good point. Peggy may be seriously driven and give the appearance of uptightness, but some of the funnest moments in the show is her dipping the pool into new ways of subverting society's expectations of women. Plus, she provides a window into the era's youth culture.
