Chapter 523. A marine reports in that they're having trouble processing the 500 Pirates Kizaru captured on Shabondy into Impel Down. Hawkins, Drake, Apoo & Urouge got their asses handed to them. It wouldn't be a far stretch to imagine they were arrested….
The four of them were down, but not out, heck Apoo was actually getting up when we last saw him and Drake and Hawkins were not far behind. The way I see it Kizaru was focusing on the strawhats at the most they had to deal with a damaged kumabot and some marine fodder. Plus Hawkins' crew was right there and I doubt the others were far behind.
