One thing that still bothers me
Oden words "don't ever come back to Wano again"
If you really thinking of killing the person or you can kill the person why say such words?
Even when Oden writes in his letter, he talks about beating Kaido not killing him.
Oden could have hurt Kaido badly the second time but I don't think he was gonna kill him or else he would not tell Kaido "don't come back"
Anyway, Kaido still has PTSD of the onlyan among top tiers to every wound his skin.
￼People that said Kaido won't have slumps or PIs moments... Stop downplaying BM for her PIS moments
