is one piece episode 808 filler?

Remembering Judge's threats on his hands and Zeff during his return to the Germa Kingdom, Sanji stared in shock at Luffy as his captain raced toward him. Luffy grabbed onto the carriage to talk to Sanji directly, and with everything against him racing through his mind, Sanji made the decision to kick Luffy away and claim that he has forsaken the Straw Hats and embraced his royal heritage as prince Vinsmoke Sanji.

Sanji claims that he will be happier in the ranks of the Big Mom Pirates, where he will be treated to power and luxury as opposed to the meager existence of the Straw Hats.
