is one piece episode 43 filler?

Luffy notices Nami's old pen covered in her blood, revealing the abuse she endured as Arlong's cartographer. After Arlong boasts about using her for his own personal gain, Luffy breaks the Kiribachi's blades with his hands, then destroys the sea maps and furniture in the room.

The spectators outside the base notice the furniture being thrown out of the building, which is also seen by Nami, who thanks Luffy for doing so. Arlong angrily bites Luffy's shoulder, but Luffy manages to break Arlong's nose.
