is one piece episode 422 filler?

Vice Admiral Garp talked proudly to Ace at Impel Down about some of Luffy's actions, and mentions that they both have the blood of a world class criminal. Ace claims that Whitebeard is his only father since he took care of him after he went wild.

Meanwhile, on Vice-Admiral Momonga's ship in Boa Hancock's disguise, Luffy is worried about Ace. On the deck of the Marine Ship, Momonga spotted Captain Buggy's ship and it seems familiar to him.

The Buggy Pirates spotted a Sea King that emerged adjacent to them and fell back into the sea.
