is one piece episode 505 filler?

Luffy is still devastated over Ace's death. Meanwhile, Garp visits Foosha Village and sinks three pirate ships on his way.

He assures the villagers that the village will be protected under his name. Dadan then storms out of Makino's bar and pummels Garp for not doing anything to save Ace at the war.

Makino stops Dadan from doing anymore harm, and says that Garp must be the one suffering the most. Dadan says that that's not true, and that Luffy must be the one suffering the most because he loved his brother so much.
