is bleach episode 147 filler?

With Runuganga having survived Rukia Kuchiki's Tsugi no mai, Hakuren and risen out of the sand before Bawabawa, whom he and his friends are riding across Hueco Mundo on, 6th Division Lieutenant Renji Abarai expresses surprise at the former not being dead yet as Rukia expresses disbelief at him coming back after being smashed to pieces. In response, Nel Tu asserts that it is not strange for him to have more than one body to use since he is composed entirely of sand.
