is one piece episode 662 filler?

As the Straw Hat Pirates yells out across the Den Den Mushi, questioning what the commotion is about, Doflamingo soothes the citizens, blaming Law for the "Abdication Incident" that occurred earlier that day. When Luffy angrily demands to know what the Shichibukai has done, Doflamingo states that it is none of his business and that, since Law was his former subordinate, he is entitled to "discipline" him.

Zoro then quickly charges at Doflamingo, asking Kin'emon to take Law out of danger.
