"Cut to Yamato's side. Momonosuke is angry at himself, saying that everyone is overestimating him but actually he's weak and useless. Shinobu says he's admirable enough, Momonosuke shouts that he isn't at all. "
Oda is basically copy and pasting Sanji's Ennies Lobby Storyline. First the whole BM/Khalifa shit. And now this obvious set-up that Sanji will be the one that gives Momo confidence and makes him into a "man". It will be a copy and paste of the Sanji/ Usopp scene most likely.
Sanji probably telling Momo he will stop King whilst Momo stops Onigashma from falling onto Wano. The set-up is already there that Sanji is the only one who gives him confidence
Interesting how Oda always makes Sanji be the one who lectures the younger ones on what it's like to be a man
And since he learnt all of these thing from Zeff....
At times Oda really does have good consistency.
