I think that's what I'm ultimately looking for is more of a balance with the frat boy stuff. It really does feel like we get an all or nothing depending on the episode sometimes. I agree that there have been great episodes that show a bit of both ("Agent Afloat" is a good example of that) but then there are episodes where it feels like he hasn't grown at all in the past 6 years.

But maybe that's just me looking for my specific tastes in the show.
