We already had the moment of failling, of hopelessness with the alliances when the ships and the entire alliances got seemingly destroyed by Orochi (even though we know it's fake). I don't think Oda is gonna make the Alliances fail again. At best, the 9 scabbards will face Kaidou and Orochi by themselves, got destroyed and humiliated. At the moment of despair, the Alliances appear out of nowhere and take the fight to Kaidou
They will go there alone, to realize that Luffy was already there ahead of them! As usual, he goes on ahead LOOOL, Not following the plan hahahaha.
No but seriously
Jokes aside.
I HOPE, TRULLLLLY HOOPE. that this is all an act between Kinemon and SH alliance. Specially from Kinemon. Kinemon has been hinted to be a "smart strategic" member of the retainers.
If there is a traitor, or a spy. HE NEEDS to be the person to discover it.
I don't want Kinemon to get everything on a silver plate. He hasn't really done anything. So, at the very least, he should be someone who orchestrated TWO PLANS. The first is the decoy, which is happening now, and the second is the REAL PLAN
Specially since the retainers know fully that 20 years ago, during the battle, Kaido hinted at a spy/traitor. If not a single member (specially Kinemon who's considered the wisest among the bunch) didn't consider a plan to take him out. Then, he really doesn't deserve a dime of help!
