is one piece episode 469 filler?

The Marines are surprised that Boa Hancock protected Luffy from Smoker. Hancock then gives Luffy the key to Ace's handcuffs.

Luffy hugs Hancock as a way of thanking her. Hancock is so happy that she fell to her knees in a swoon.

The nearby Marines mistook this interaction as Luffy throwing his weight on Hancock and defeating her. Hancock then pictures herself marrying Luffy and having the red string of fate tying them to each other, but is soon brought back to reality when Smoker attacks Luffy again, prompting Hancock to break his jitte.
