is one piece episode 67 filler?

Having defeated Mr. 5 and Miss Valentine, Luffy and Zoro turn back to each other, prepared to resume their own battle. Vivi and Karoo watch helplessly, still shocked that they beat a Baroque Works Officer Agent pair so easily.

But before they can strike their first blows at each other, Nami knocks them both silly. While Luffy finally understands why Zoro was fighting Whisky Peak's denizens, Nami presses Vivi on a 1 billion contract to return her to the Arabasta Kingdom.

Vivi says it is unlikely she will be able to pay due to the brewing civil strife in her home kingdom.
