Attention Superfans!

Hi fans of Madam Secretary--The whole series captivated me--and that's why I'm doing a study on its effects on viewers. I'm a communications researcher, and I'm hoping to crowdsource some help. We're hoping to do a study that measures the effect of Elizabeth's leadership--as a strong female lead--against any episode where the males are in charge (as a control). I've been going through the series again trying to find the best stimulus (Elizabeth in control) and control (men in control) episodes that still are reasonably dealing with the same issues/on the same end of the political spectrum so that we can control for as many variables as possible. Who better to ask than the superfans? What have you got--what episodes should I be taking a closer look at?
