is one piece episode 498 filler?

Ace, Sabo, and Luffy chase down a Danpa and succeed in catching it, but a tiger steals it. To get revenge, the three brothers put fish on their backs to lure the tiger, but a bear that can match the tiger appears.

Ace attacks the bear, but it gets angry and chases the three brothers. It is then stopped by a former pirate captain named Naguri using Haki.

Sabo reveals that Ace is related to Pirate King Gol D. Roger.

Luffy asks Ace about Roger, but Ace does not like his father being mentioned, so Sabo, Luffy, and Ace say that they will break their relationship as "brothers".
