Se have no full explanation of that, but since the raid was a success seems like Kidd stayed just the time to injure the Sweet Commander (Smoothie, Cracker or Snack) and the left with what he needed.
And he did so while Luffy was dodging animals and Zoro was fighting babboons.
It's true but we always come back to the same point it would seem that has not beaten anyone of note in the new world type Doflamingo it is exactly the same thing for Law.
Not sure if you get my point Zoro and Sanji are going to beat King and Queen who are 1v1 monsters like Katakuri. But Kid and Law haven't beaten anyone of note.
What they're doing right now is holding back Big Mom.
My question that I have been asking myself for some time is:
Zoro and Sanji are they necessarily weaker than Law and Kid in the end based on facts ?
I don't know if Law and Kid are going to beat Big Mom, maybe yes but maybe not, but for that they need a lot of help and credible Power-ups how will Law awaken his fruits in full fight , how can Kid damage Big Mom if he doesn't have the Ryou? Luffy took 2 weeks to master it. All of this cannot be done in one fight, that's the problem. I have the impression that Oda does not know exactly where to locate Kid and Law in relation to Luffy.
