kukuku.... excuses, jealousy, blaming other people. Fine episode.
Well, I guess we have some plot progression and some insight into the past. Also, Yozora went a bit too far this time against Sena, though I guess the whole fucking with people under false pretenses (So you figured out you didn't need my permission) is something that I've been guilty of too, so I won't talk too much. :S
Kodaka's being an awesome singer, and Yozora and Sena refusing to be in the same room highlights their main problem-- neither is able to admit any concessions and neither wants to see fault within themselves. But hey, as you might know, to make friends with other, you need to start with yourself.
And at the end, Sena manages a minor comeback by making Yozora insanely jealous. Yozora is clearly the worst person in the group atm, so hopefully she realizes that all of this is just making matters worse.
Also Rika... licking that mic.
