You know, before this episode, I all but hated Yozora. I really didn't care much for how she treated some of the others, especially Sena and Maria. I kind of forgave Senas case since a) it kept her from becoming too full of herself and b) well...it was funny. Maria on other hand, I couldn't quite understand until now. I don't know why it took me so long to realize that she can be a real brat at times. So, I guess Yozoras treatment is needed to keep her in place. I guess my point is that its easy to misjudge people until you see things from their point of view. I dare say that shes actually kind of...cute?
Overall, this series has exceeded my expectations. I came into this series looking for a good comedy. While I didn't find it as funny as the manga, it surpassed it on every other level. Really though, I felt this series could have been a bit longer as some things felt rushed and there was good material left out. Still though, I had to drop several series this season due to various reasons, but I'm glad I didn't drop this.
I also recommend the manga, especially if you can't get a hold of the LN. Atleast the first. There's another one called "Boku wa Tomodachi ga Sukunai Plus" which has him meet Sena first and they are the ones that start the club. Its OK so far (it only has three chapters), but I seem to enjoy the original storyline better.
