^ Except that Pierce's behavior this season was very clearly stated it was partially induced by the pain killers he was dealing with and his issues with his family. After thinking about his little speech at the end of the finale, he probably did need the study group for self-counseling. Now that he has basically admitted that to himself it will be interesting to see how season three deals with this, and how the group feels about what he said. I'm sure they will blame themselves for what he said. I like how Pierce's arc was paid off.
I think my favorite episode of this season was "Abed's Uncontrollable Christmas". It pretty much had everything in the episode. Plus I think the episode is an example of John Oliver's finest work on the series. He was brilliant in that episode. No, I think overall season two was as strong as season one was with one or two duds.
