Nova, i am not talking about a better flashback, just the cliche excuse.

Kaido, neither do I man, the closest I could come up with was that Dragon didn't let him go or he had something else to do like a mission but neither makes sense because if Dragon didn't allow him it seems out of character for him and contraticts the absolut freedom he seems to be fighting for, and no mission could be more important than saving your brother. So yeah the only legit reasons left were the amnesia thing or that he was imprisoned, so even though I don't like it I can't say that it was a plothole.

I never said that it was lazy writing because somebody predicted it, amnesia was just the easiest excuse he could come up with for not wanting to reintroduce him in the war or earlier in the series which is ok, i was just expecting something better.
