I'm not a fan of BSS's encoding. The raw is much larger, but it just looks better. Like Munsu, I really don't see why it's an issue. A subtitle file is still a fansub. You can easily edit the file too, which is a plus when it comes to BSS.

Back to the episode:

I'm surprised to see the second verse of the song instead of a new song for the OP. After Kamina died, Yoko wasn't much more than a side character. The most significant thing she did was shoot Nia's hair and accepted her. It's a little sad she wasn't of much use outside the Kamina Arc.

I wonder how long Rossiu has been like this though. Since the fall of the Helix King? His organization within the government is huge, and comprised exclusively of people that were not prominent with the Gurren-Dan (excepting Kinon). He certainly seems to want to take control instead of Simon, and keep him only as a symbol. A return to his perfectly regulated underground society. Nice to see Simon thinks more like Kamina, even if it got a lot of people killed. What was Rossiu going to do, let it kill half the population with its laser?

More confusing to me at least was Rossiu's line "You don't understand at all," right after Simon accused him of wanting to turn the world into a large version of his old town.
