is one piece episode 493 filler?

Ten years prior to the story, there was the peaceful Fusha Village. Mt.

Corvo was the most treacherous. Garp dragged his now rubbery grandson Luffy along, hoping to make him a Marine instead of a pirate.

Curly Dadan was surprised by Garp's presence alongside mountain bandits Dogra and Magra. With Ace now ten years old, Dadan's family think they will be turning Ace over to Garp, but he left Luffy in his care.

If Dadan's family didn't raise Luffy, they could spend the rest of their days in jail. Curly Dadan is angry with Luffy's presence.
