Sanji was caught by Maria just to let Robin show up and save him
Oda has always been like this. Because Sanji can't beat women, he always lets Sanji meet female enemies. This is his evil taste
The reaction to Yamato Sanji was normal, and Sanji was the same when Robin joined
Zoro is also lost in Wano. You will find that Zoro is lost in every big chapter, and even the knife is stolen. This is the same as dressrosa. Is this stupid?
Zoro gets lost and Sanji is caught by a woman, just to pave the way for the next story
You shouldn't take it seriously
