is one piece episode 807 filler?

On the Baratie two years ago, Sanji gave food to a starving Gin. Luffy watched this affair, and asked Sanji to join his crew as the cook.

Later, during the battle against Don Krieg, Sanji watched in amazement as Luffy fought fearlessly, risking injury and finding creative ways to take down his opponent. Back in the present, Luffy and Nami ride Kingbaum out of the Seducing Woods, and Nami talks to Chopper and Carrot through a mirror shard.
