We've come to what might be the turning point in the arc. Not only do we know how Dressrosa wound up the way it was, but the biggest knot (Sugar) has been undone, while Sabo has unwrapped the Mera Mera. We can expect to see how everything else strings together, but where might the threads lead? Let's take a look at the current loose ends!
Not much speculation here, but some questions - I expect them to be most probably answered within this arc or so. (speculative fan stuff in brackets)
- Where is Kanjuro?
- Who is princess Manshelly?
- What is the grudge that Traffy has against Doffy?
- What is it that Doffy really wants out of Dressrosa?
- Is CP-0 still on Dressrosa? If so, what are they gonna do?
- What of the other Revo agents previously sent to Dressrosa? (Will what Robin did during the timeskip be revealed?)
- What's happened to Nami & Co.? (Will Sanji get to cook for Big Mom?)
- Is Fuji the new nice-guy Marine who helps clean up afterward, much like Smoker and Aokiji?
- What does Doflamingo want with Momo? [by Hawk]
- (Will Traffy give Kyros a new leg?)
What do you guys think might happen? What else ought to be added to this list? What would you like to see?
Hopefully I'll remember to update this list with the answers in the next couple of months =)
