is one piece episode 868 filler?

Flampe and her subordinates continue laughing as Luffy weakly tries to get up after being utterly pummeled by Katakuri, to the point where they do not even attempt to conceal themselves anymore. Katakuri notices Flampe's group, and then realizes that she assisted him in injuring Luffy.

He walks toward her, and as she imagines him praising her for what she did, Katakuri in reality is angry at her interference, thinking that it would make his victory cheap.
