is one piece episode 822 filler?

Having escaped the prison library, Jinbe and Nami join Chopper and Carrot in the Mirro-World Dimension. Jinbe is questioned about deserting the Big Mom Pirates and not spinning Big Mom's roulette wheel.

Pedro explains that the roulette wheel is intentionally designed to kill all those who leave Big Mom's crew. They ride on Diesel's back in search of the others.

Meanwhile, having been defeated by Big Mom, Brook is hung on a thread by Big Mom and held in the throne room. Pudding enters and reveals her true nature to Brook.
