IGN - For a circle of friends, the Community study group sure does fight a lot. Through most of last season they were arguing and bickering over one thing or another (mostly Pierce near the end). And they were at it again in "Competitive Ecology." But deep down, they all know, and we all know, that they would always be there for each other, no matter the problem. Which is why episodes that focus on their bickering can be so much fun. These aren't real fights, they're friend fights.
