First things first, the OP and ED were really well done. I think I prefer the old OP to the new one, but the new ED is definitely better than the old one. Mako is so adorbs in it. Anywho, this episode certainly had lots of reveals including some stuff i'd rather not have seen. Seriously, I needed all the adults in the world during that scene. Well, maybe not Ragyo. Really creepy. The other reveals were pretty cool. I thought for sure bio-fiber was made out of people all soylent green style but nope. That dude from the History Channel was right. It was Ancient Aliens all along. I guess this is why Junketsu is super dangerous and stuff. It's actually made from the original bio-fiber and not the synthetic one like Senketsu. And speaking of Senketsu, Ryuko is so adorbs caring about his feelings like that. She makes you forget that he's clothes and not people. The way she was acting makes me think that she'll try to make humanity and bio-fiber co-exist instead of outright destroying it. Because that's the way all anime heroes are. Anyway, I guess Ragyo is planning on using the bio-fiber in regular people's clothes to either control them and have them take over the world, or maybe have people offer themselves up to the main bio-fiber thing. Guess we'll just have to wait and see what happens at the sports and culture festival. Gonna be fun on a bun.
Overall I give this episode an 8 out of 10. Would have been an 10 out of 10 simply because of all the reveals and stuff, but that whole shiznet with Ragyo and Satsuki really put me off.
Sidenote: Old man Isshin in Mako's daydream was fucking hilarious. I don't care what Ryuko says, that is totally why the old man created Nudist Beach. And also, dat stupid sexy sensei. So good. Even Mako was enthralled by his gloriousness.
