Birthday episodes are a good opportunity to showcase the extremes of your characters' emotionality. Internal stakes are always higher on birthdays. For the central figure, there's the unwitting assignment of importance to the date - the hope and expectation that the night in question will carry some symbol of new beginnings, or that it might quell long held insecurities. For the surrounding parties, there too is heightened sensitivity, be it due to the observation of a friend ascending in contrast to one's own stagnancy or maybe just a little too much booze. Whatever the reason, birthdays are a miserable catastrophe, both on television and in real life. And this week on Girls, we endure Hannah's. The big 25, no less.
