Basically nothing happened in this episode... And with a lot of these recent ones, too. I really loved the premise of all the Marines and Shibuckai fighting against Whitebeard's army, but this has been dragging out for so long, and there's a few eps of the arc left. The previous episode literally ends with Luffy asking Ivan, but it's not until the last 2 minutes that that question / scene comes back... Of the 15 minutes of actual time spent on the episode ( 5+ mins for the opening creds and prev. ep flashbacks ) and the last few minutes of end credits, excluding the mid episode break animations, there's really only about 10 minutes of actual story going on here - and that's being generous. I understand that this is just a thing most animes do considering how much effort has to be put into each singular episode, but I'd rather quality over quantity.
