We saw Zoro saying on "Don't let your guard down" (Specially to Luffy) on multiple occasions since they entered on New World.
- On punk hazard
- On zou(was actually about bm, but i thought i'll just include it)
- And rn in wano
Like on Punk Hazard, robin, franky, (smoker, tashigi).
On wano he let his emotions get the best of him and attacks some kaidou fodders which results to kaidou attacking oden castle where nami and co are, (if it weren't for plot armour they would have been dead). And after that he attacks kaidou despite law convincing him to not to fight yet and he lost, which led to let him train bout the haki.
And zoro is a very keen observer, remember when luffy said "i wonder when will jimbei comeback" and zoro is just "...." implying that he's observing luffy.
As u can see on the 1st pic he was like "Oh!!!" (Let his guard down), mesmerizing zoro cutting prometheus, and just standing there tapping his head(?), and on the 2nd pic zoro said that "don't let your guard down luffy, we're up against 2 yonkous" which leds to kaidou about to hit him and luffy was kinda shocked(?) ( i don't know the word) and he was like "Wha-?" which leds to law saving him. And on the 3rd pic they just let themselves get hit by prometheus, and zoro was angry about it.
Yeah i know, luffy is "Free" about his decisions but being "Free" sometimes endangers others.
My point is zoro is telling to luffy that "Don't let your guard down, because if you do it will cost your life and the lives of your crewmates, we're in the new world now we need to be serious or else..".
And i want to add something, do you think Zoro will confront luffy about this? After the end of wano? And also on sanji's case since i think zoro will not let this slide.
And i'm sorry if this is confusing, i'm just so bad at this kind of things.
Give me your thoughts thanks!
