He knows he'd needed elsewhere to do more important things.
Queen has bigger problems then Zoro and Sanji at this point.
What important things? Are you forgetting that its Zoro who tells Sanji to go to the live floor in this chapter specifucally because Sanji HAS NOTHING TO DO NOW. The scabbards are fine and are going to go help Momo.
Those are the TWO things YOU, CHRONO, YOU were saying for weeks are Sanji’s mission. Then instantaneously those TWO thing YOU, CHRONO, YOU kept saying were Sanji’s important thinhs got resolved WITHOUT his intervention
Then Zoro is the one who actually tells Sanji what to do after the important things YOU, CHRONO, YOU were saying are done with.
So no, Sanji does NOT have MORE IMPORTANT things to do. Sanji will do what the plot says he will do. This time the plot is Zoro telling him to go to the live floor for no reason other than thats what the plot requires. So that he runs into QUEEN, the only other beast pirate Sanji has any actual Plot with.
