is one piece episode 385 filler?

In the Holy Land of Mary Geoise, Kuma appears before Sengoku who demands why he let the Straw Hat pirates go. Garp accepts his grandson's tenacity to the anger of his superior.

The older admiral says that no one will believe Luffy's story on how he had beaten Moria. Sengoku knows that because Kuma showed compassion to the Straw Hats, if they follow their log pose continually, they'll reach the Navy Headquarters.

Garp then presents some tea that Sengoku rejects.
