Zoro and Franky will appear. Luffy will beat his double senseless, upon seeing it, the other fakes will try to run only to be intercepted by their real counterparts, showing off their newfound powers while beating them senseless. That's the first three pages. Then they tell each other what they've done over the last two years for the next 15/18 pages.
