Sanji did not comment on Vergo trolling him. Vsually we saw how he did it. I guess Sanji's face said as much :)
Visually we see what the fuck is going on. No, the beak wasnt so bent originally. now its bent shape is very conspicuous lol
But Oda can choose to delay this reaction from King because we actually later get some context for how Sanji could've achieved this, ie through his hardening defence. Sanji chose not to harden up against Black Maria because he would hurt her if he did. If Oda would've laid out how King got his beak bent, that scene wouldn't have been as impactful and surprising.
That's just one example why he perhaps didn't want King to call out what had happened to us, the readers. He can have other reasons, what the hell do you or I know? All I know is what I see lol. You expect to see blood and bruises, wtf lol. You're riddiculous
@BakiDou yeah very lowlife shit lol
