is one piece episode 603 filler?

In the New World, a broker is left stunned at how Caesar Clown was able to capture the Shichibukai Trafalgar Law, the captain of the once again active Straw Hat Pirates, the "Devil Child" Nico Robin, and the great Vice Admiral Smoker. Also watching the broadcast, Killer tries to point them out to Eustass Kid, only for his captain to comment in an amused manner about Luffy's return.

He then tells Killer that watching is meaningless, and how he does not think Killer ought to work as a broker anyway.
