is one piece episode 809 filler?

Inside her throne room, Big Mom reacts in shock and anger to the report of Cracker's defeat. Trembling with rage, she summons her homies Zeus and Prometheus to her side and mutters Luffy's name.

On the outskirts of Sweet City, Luffy lies on the ground panting, and Nami brings up the account of the Big Mom Pirates' rage when their last Sweet Commander was defeated. She, Luffy, and Kingbaum then look on in awe and fear as they see dark clouds coming out of the Whole Cake Chateau, remembering Pound's account of how the same thing happened last time.
