is one piece episode 690 filler?

Bellamy reaches the palace rooftop, and Doflamingo asks him why he came. Bellamy then asks if it was really Doflamingo who sent Dellinger to kill him, wondering if he can no longer do anything for Doflamingo.

Doflamingo laughs, and tells his former underling that the two of them had different goals from the start. While Bellamy was content to be an ordinary pirate, Doflamingo's main goal was to destroy the world, which seemingly horrifies Bellamy.

Elsewhere, the Corrida Colosseum fighters continue toward Doflamingo's castle. However, Dellinger focuses on one fighter: Suleiman.
