is one piece episode 248 filler?

Franky, angry, charges in and attempts to attack Kalifa for injuring Mozu and Kiwi but Blueno blocks his attack using Tekkai. However, Franky manages to pick up Blueno and overpowering him while yelling at the CP9 agent.

Blueno attempts to use Shigan on Franky but Rob Lucci stops him saying they need Franky alive after kicking Franky away. Usopp is surprised at Franky thinking what he did to get Lucci and the others mad (still thinking they're with Galley-La).
