is one piece episode 416 filler?

After telling Luffy all about her past, Hancock agrees to give him a ride to Sabaody Archipelago with her Yuda-towed ship. She also invites Luffy to their banquet tonight and to rest inside.

While Luffy expresses how excited he is to see his friends again, Hancock looks back with a confused look as she realizes she's still blushing. Nyon comments to herself how amazed she is that Hancock is trusting Luffy so much and Hancock places her hand on her forehead seemingly uncertain what she's feeling.

At the banquet, Luffy eats everything around him, and the girls seem suspicious.
