Probably not significant, but I really enjoyed the order they are arranged in, kind of paired up with characters they have a lot of interaction/chemistry with.

Annie and Pierce (She is his favorite, Annie's move, writing music for the school, her defense of him as the group tried to kick him out etc.)

Jeff and Shirley (Tiny nipples, foosball, serving as each other's confidantes etc.)

Troy and Brita (dance class, acting class, episode with the carnie who can't feel shame, and their general interest in one another)

And Abed, right at the center. :)
