Ah... ok.
So Oda had a nerfed Zoro using a low tier attack and oneshotting a nerfed Killer, who couldn't even touch him without taking advantage from an external involvement...
To then have them as equals.
So Oda had Kidd (who has always has a cocky behaviour) do nothing and sincerely praise what Zoro did, and thank Zoro for saving him and the others...
Even if Kidd was strong enough to do the same, but for some reason he chose to not to.
So Oda had Killer in awe for Zoro's feat of cutting Kaido's tough scales, and had him screaming that nothing can be done and then had Zoro save the situation...
To have them as equals.
So Oda had Law in awe when he was Zoro attacking and wounding Hybrid Kaido in a fair and square 1 vs 1...
Because he could the same if not better.
So Oda enlightened Zoro's performance far more than anyone else not named Luffy...
Just to get rid of him quicker.
The headcanon is strong here.
The denying of blatant evidence is strong here.
