is one piece episode 482 filler?

Marineford begins to crumble around the Marines. With the island coming down, much of Whitebeard's crew don't want to leave their captain behind.

Angry at their insubordination, Whitebeard tells his crew to evacuate. The Marines continue to rapidly fire bullets at the large pirate who slams his spear down, blowing some Marines away.

Some of Whitebeard's crew despair, but Fossa says that evacuation is what Whitebeard wishes his crew to do. With the pirate crew leaving, Luffy calls to Ace who is standing still.

Marco also despairs at Whitebeard's situation.
