is one piece episode 635 filler?

The episode starts out with Franky in the stands, exclaiming his shock to see such a powerful competitor as Jesus Burgess, thinking that Luffy would win the tournament easily. He then gets up to leave and do his job, but the Thunder Soldier says that he wants to go too, much to the annoyance of Franky.

At a northeastern cafe the members of the group responsible for exchanging Caesar are asking about Green Bit, but are told to avoid it saying that there are fighting fish which are very dangerous. He also says that no one who used the iron bridge to Green Bit has ever come back.
