is one piece episode 694 filler?

Viola searches for the entire palace for Mansherry, trying places she had never been in in her years serving the Donquixote Family. Viola then relays the information to Leo and Rebecca to which Leo expresses his worry for Mansherry.

Viola tells him of the location and he realizes its the "time out" room. Leo then gets tearful as it reminds him of Scarlett and that whenever he and the others visited the palace they'd get in trouble with Viola by Doldo but Scarlett would bring them food to which Leo admits he misses Scarlett.

Leo thanks Viola for the information and she tells him to be careful.
