is one piece episode 488 filler?

Buggy carries the unconscious Jinbe and Luffy while insulting Law being a doctor armed with a sword. The Marines recognize Law for aiding and abetting in their fight with the World Nobles at Sabaody.

Law calls for Buggy to bring the two pirates to him and the clown dodges a cannonball. The Navy ships begin to close in on Law's submarine while Akainu gloats that Luffy may not do any favors even if he survives the day.

He could be the undoing of the Whitebeard Pirates. As the admiral fires a Hound Blaze, the crew of Whitebeard give fire while Marco charges the lava hound.
