is one piece episode 495 filler?

Despite being beaten up by Porchemy, Luffy insists on not saying a single thing to them about Ace and Sabo`s theft. Then Porchemy decides to go on the hard way and brings out his special sword.

The moment he was going to kill Luffy, Ace and Sabo on a rush destroy the room they were in and fight Porchemy. Ace tells Sabo to pick up Luffy and make a run while he`ll be confronting Porchemy.

Sabo asks why won`t Ace escape with them on which he replies that he never runs away from a fight. Sabo then gets into such a situation, that he leaves Luffy on the ground and decides to fight alongside Ace.
