He helped set up Robin vs Black Maria and even got a wholesome moment about trusting her.
He also got to rescue Zoro and gave us the holy cross.
It wasn't all for nothing.
Come one man.
He went for the scabbards....BUT,
he heard about Momo...where will he go now? THIS NON REVEALED WAY!....BUT,
Law dropped Zoro on his shoulders, but he is still going for Momo....BUT,
he finds the scabbards, now he goes back to the Live Floor because reasons.
It's the same as with Yamato. THE ONLY REASON Yamato left Momo's side, was so we could have the scabbards moment against Kanjurou.She leaves TO GO FOR KAIDO.
One chapter later, Kaido is there, so she needs to turn back to fight him.
You do see the pattern that Oda does of moving pieces without any real need, only for them to end up in the same place again? It's fucking annoying.
