is one piece episode 245 filler?

Paulie is still in shock that the people he thought were his friends, Rob Lucci, Kaku, Kalifa, and Blueno, are actually with a secret organization known as CP9. Luffy recognizes them from the shipyard and Zoro remembers Kaku as the one who inspected the Going Merry.

Nami says that the attack on Iceburg was an inside job but Chopper is still confused. Lucci informs Paulie that they work for the World Government and threatens to attack Iceburg.
