is one piece episode 514 filler?

The episode opens with Nami, as she is reading the newspaper containing Luffy's recent actions. Meanwhile, the old men catch up to Nami.

She eventually confronts the old men. She then proceeds to trick the group, going on how one of the old men suggested that they strip her and beat her.

Haredas remarks on how Nami has the group under her control. Nami then proceeds by telling the old men that she will jump off the island.

She takes off her shoes and sets them down in front of her, apparently preparing to throw herself into the ocean.
