is bleach episode 234 filler?

In the Seireitei, at the 4th Division barracks, 8th Division Captain Shunsui Kyōraku notes there are still no leads and tells a Riteitai kneeling in front of him to keep Shunsui posted on his findings. Agreeing to do so, the Riteitai moves away with Shunpo.

As Shunsui thinks about what he has been told, the door opens behind him as 13th Division Captain Jūshirō Ukitake enters the room. Closing the door behind him, Ukitake asks Shunsui how it is going and if he has discovered anything new, only for Shunsui to deny this before stating he has not learned anything very helpful.
