is one piece episode 850 filler?

Pedro's massive sacrificial explosion engulfs the entire surrounding area, knocking Big Mom down as well as freeing the Thousand Sunny, Chopper, and Brook from their candy entrapments. A distraught Carrot tries to go to the scene of the explosion to desperately try to see if Pedro survived, but Nami holds her back, saying that Pedro gave his life to give them this chance to escape.

Luffy prepares to have the crew activate Coup de Burst, but Katakuri still remains on the ship. He asks why everyone is so heated up, and Carrot activates Electro as she leaps at him in a rage.
