I think it was a pretty good episode overall, but what was most interesting was the bit of filler that was added in Zoro's and Drake's conversation about the side he was on and his identity which was a bit more than what we got in the manga. He obviously can't reveal his true identity, but perhaps the Strawhats will learn about it anyway at some point in the future. Perhaps Post-Win?? [Though he has basically told Zoro in so many words. Cool stuff.]
Their skirmish was cool, but they didn't go all out in the manga to reserve strength for future battles and was portrayed pretty well. There was an interesting lighting effect as their swords clashed--like static or lightning though that couldn't be it. I'm glad that it was cleared up that Zoro WAS using Enma against Drake though. That was pretty cool!
Sanji's comment was dumb and I'm glad Nami called him out especially since Drake didn't even see Nami in the manga, it was some geisha woman. SO!! That was hilarious! On a cooler note the fact that Sanji was added in recognizing Page One, was good. Ancient Zoans are incredibly tough indeed!!
Nami and Usopp are a great team!! It was only the funny bit, but I can't wait to see them again as well as everything that happens in the next episode. It looks pretty. 4/5 here.
Oh also. It was satisfying to see Luffy confirm not once, but twice that Drake could join him and Drake's response on par for his character. He really had his doubts but Luffy with his ability to read emotions is just different!
Edit2: Zoro and Drake versus Apoo was cool too. Their combine attack while not super crazy was nice with them with pretty much voicing the same opinion of Apoo needing to stop doing dumb shit. A funny moment in a way to be sure, but that aside, it's interesting that Drake repeats in the anime that he can't be put down by (machine gun) bullets. Can he just deflect or just dodge like he did?? Or something to do with dino toughness?
I wish Drake would lay more of his cards down. It's frustrating.
