is one piece episode 486 filler?

Whitebeard is now dead. The people at Sabaody watch in shock.

Some civilians learn that with Ace and Whitebeard dead, it will shake the foundation of the world. The news is spread across the world; Ace was killed at Marineford and Whitebeard died in the failed attempt to save him.

With the Marines seemingly victorious, some people begin to cheer at this news. Rayleigh also watches bidding Whitebeard a nice journey to the afterlife.

As Teach is exhausted, the people learn Whitebeard's real name was Edward Newgate, who stood against Gol D.
