is one piece episode 828 filler?

The Sanji Retrieval Team meets with the Fire Tank Pirates, and before any words are exchanged, Luffy helps himself to food from a bin on the table. Bege begins by saying that he considers the Straw Hats to be pests, and wonders why he should not kill them.

Sanji points out that killing him would prevent the wedding and ruin Bege's plot, which Bege concedes to. Luffy sits in silence for a while before he finally recognizes Caesar Clown, who has slicked up his hair and is sitting with the Fire Tank Pirates.

Caesar gets scared when Luffy recognizes him, remembering how he got to be here.
