is one piece episode 423 filler?

Upon entry to Impel Down, the Surveillance Den Den Mushi glares for anything suspicious. Boa Hancock believes Domino will make her powerless.

Just as Domino is about to apply the Seastone handcuffs, Hancock flirts with the guard and fires a Love-Love Mellow beam at her, turning Domino and the Den Den Mushi into statues. With the guards in shock, Monkey D.

Luffy comes out safely. Hancock insists that it is where they part ways.

If she had removed her cloak, there would be no place for Luffy to hide.
