is one piece episode 573 filler?

Camie tells Shyarly that Luffy and his crew are going to leave the island. Shyarly tells her to go see them off.

Before she leaves, Camie notices the broken crystal ball on the floor. Shyarly tells Camie that she is through with foreseeing the future for good, and she could not be happier if she was wrong.

Camie realizes her boss is more fearful than anyone, since her prediction may come in a year or more, and there is no way to know if she is wrong. Shyarly asks Camie to forgive her for suspecting her friends of wrongdoing.
