To paraphrase Harlan Ellison a boy loves his sword. Unity is my favorite because it shows IY's true relation to Tessaiga. I am glad that they ran the entire manga section since it is so important. I agree that things got jumbled around since Byakua and the backfire of Tessaiga occur early than the scene with Kouga and Kai. By the time that scene occurs Tessaiga no longer backfires. The scene between Naraku and Byakua just like the backfire comes after the battle with the Mizuchi. The Kai story is important because Kouga realizes that it is his presence that is causing the wolf demons to be killed. IY respects Kouga's feeling for his fellows and you get the feeling that maybe they are closer than they appear. What it does not show is the way Naraku is manipulating the battle between Moryoumaru and Inuyasha for his own amusement.

I am not sure why they included Ginka and Tinka. As far as I can see it adds nothing. I was surprised to see them add Yoursei-Taisei to next weeks show except that it will teach us about Youketsu.
