I see what you're saying. I don't know their science behind crafting these episodes, and who gets the final say on what.

Check out pages 5-7 of chapter 635: http://onemanga.tv/one_piece/635/5/

So yeah.....that flashback? Never happened. All that dialogue between Zeo, Zoro, and the shell squad beforehand? Never happened. In the chapter, Zoros swords all point towards his left for the Kokujo O Tatsumaki, with Shusui's blade side facing up. In the anime, they're all pointing to his right. I can now see a basis for why so many people complain about the animation of the show. People that didn't read the manga (guilty) but watch the anime can easily see things that didn't really happen due to the padding. For instance, some people have starting theorizing that the block of the big baboons attack is what caused his eye to get messed up. Sad.
