Luffy never had any connection to Kizaru and even after fighting one full round against him, no connection was found between the two.
Zoro vs Kizaru at this point may not be likely considering that Oda's goal in this arc is to get nothing done.
The only people he managed to write off in this arc are Vegapunk's satellites.
If Zoro sweeps in and KOes Kizaru as Sabaody payback, it would be sweet but I am not counting on it after Buster Call...
Shitty that an Emperor has to retreat from such a measly threat... Even after officially being one of them, Luffy still doesnt have the presence of an Emperor that WG thinks twice of even bothering let alone forcing out of a certain territory...
It may be time to introduce some 3rd party that lingers around Egghead and fk off to next island, whatever it may be.
