Sounds like a fun chapter. I hope Luffy and Shamrock encounter each other before he goes. 3 Holy Knights with him excluded vs the Straw Hats and all their allies doesn't sound too crazy. At least if Luffy and him face each other, the other 3 can be faced by strong characters around.
Gaban is pretty hype for handling Luffy so well and making him bust out G5. A tag-team would've been interesting, but that even being on the cards is pretty good hype for Gaban. Hopefully we see more from him, maybe against one of the Holy Knights. Gaban hype is great, but I expect Sanji hype soon, can't go off of future stuff too long, I want to see gradual growth from Sanji on-panel.
I'm sure with the arrival of the other Holy Knights, we'll see the crew focus on them since Gaban gave the key. If Cerberus is still around, I'd expect Zoro to handle it, and for the crew to unlock Loki given the situation of new unknown enemies around.
