True but I was already aware how easily people could mistake that scene, but that translation isn't exactly in good quality, which doesn't help.
You might have as well used the official anime translation.
[Hina]: Smoker-kun! What on earth is this rain?
[Hina]: Don't tell me you used the Dance Powder?!
[Smoker]: You idiot.
[Smoker]: I do know better than to commit a crime.
[Smoker]: The Alabasta King kept his hands off of this powder. What's the point in me going against his morals now?
[Hina]: Oh, excuse me. Hina apologize.
[Hina]: I can't believe the "White Hunter" of all men would say something sweet.
[Hina]: I wonder if you've mellowed out a little…
[Smoker]: That's none of your business.Also, it really is one thing for Smoker to mellow out after he finally caught Luffy/Straw Hats only to have his life saved, then makes the decision to let the Straw Hats go for now - which Hina notices. It's another to say Smoker, out of all people would commit a crime, especially when it'd be like spitting on King Cobra's and the people of Alabasta's morals.
Of course he's not going to admit on record.
But dialogue aside, what's with Oda's comment on the side?
