is bleach episode 211 filler?

Two Shinigami are on patrol when they notice Captain Shunsui Kyōraku, who thanks them for their effort. Kyōraku tells them that he is having trouble sleeping and turns around, noticing Aizen.

Kyōraku nods, commenting that he was just being paranoid. The two Shinigami become confused, but Kyōraku quickly covers up by saying that Aizen must be having trouble sleeping as well, and tells both of them to go to bed soon.

Kyōraku returns to the Eighth Division and notices Nanao Ise. He greets her and remembers that it is the first day of the month.

Nanao tells him that he was hoping she could read with Lieutenant Lisa Yadōmaru again this month, but is told that she is away on a mission.
