is one piece episode 235 filler?

The episode begins with Usopp waking up after he was beaten unconsious by the Franky Family. It is also noted that Nico Robin has not yet returned to the ship.

He is informed by Luffy that the stolen money probably can not be retrieved and that the crew has decided to buy a new ship instead of repairing the Going Merry. Usopp is enraged by this, which prompts Luffy to clarify that it is impossible to repair the Merry with the damage she has sustained.

Usopp refuses to accept this and thinks that Luffy has abandoned the Merry.
