Basically, Blair, Chuck and maaayyybeee Dan are the ones who matured through the series. Serena is still the self-absorbed, i-am-the-center-of-the-world bitch that was since season one, and Nate, well, Nate is just Chuck's sidekick. I'm just glad they kicked Jenny and Vanessa out. They really sucked and made everyone's life more complicated, not in an interesting way. GG is getting worse by the episode. Leighton and Ed's acting skills saves the series.
