Well, kind of disappointed in Marco.
Him damaging Prometheus was a great start to the chapter, but then him standing zero chances against the actual BM and simply getting ignored/left by her was a massive bummer.
The ending of the chapter was just idiotic beyond belief. Tama suddenly appearing on Onigashima (an 8-year old cruising to an island, which is notorious for being so hard to reach) was the biggest asspull I've seen in quite a while.
Compared to that brainfart even Oden dancing for five years looks like a genius writing decision by Oda ...
