My assumption:
- Starts with small flashback of Ace
- We get back to see Marco flying up Zoro/Robin/Brook
- Apoo gets back up, tries to slow them and intercept them
- When Drake is about to stop Apoo, Queen interferes and attacks drake... resulting in Brook intercepting Apoo, and tell Robin and Zoro to proceed ahead (So, it will be Drake vs Queen/ Brook vs Apoo)
- We get a small panel of Luffy running (as usual)
- Finally, while Marco is flying, Robin just drops on 3rd floor and tells them to also proceed ahead (cause she will help Sanji and she will fight Black Maria herself)
- Last page, we saw Zoro on Marco's back, both of them having the look of determination and heading up to the roof...
That's something I feel Oda will just do honestly...
