is one piece episode 682 filler?

Nico Robin moves toward the palace with Usopp and Rebecca, while Sabo and Koala split to complete different tasks. At Luffy's location, Law asks him if he knows what he is going to do and points out how their goal was to destroy the SMILE Factory in order to provoke a conflict between Donquixote Doflamingo and Kaidou.

Law claims that Kaidou will turn his anger at losing his SMILEs to them if they kill Doflamingo now. Luffy states that this is not an issue now before demanding to know what will happen to Dressrosa if he stops now.
