is one piece episode 262 filler?

Sanji and Franky have just defeated their opponents and enter train car 2 where the CP9 agents are. Kalifa comments on how loud it has gotten and Blueno and Kaku say how they underestimated the intruders.

Franky warns Sanji that CP9 uses some "weird moves" and Rob Lucci walks toward Nero kicking an unconscious Wanze away. Lucci wants to know who the man is and Kaku says that according to Corgi, he is the newest member of CP9: Nero.

However, Kaku says that Nero only knows four of the six powers and Nero gets up saying how he is going to take down Franky.
