is bleach episode 36 filler?

In the first Special Confinement Cell within the Fifth Division barracks, Lieutenant Momo Hinamori sits and holds her head in her hands as she recalls finding the corpse of her captain, Sousuke Aizen, earlier that day. As she enters the room, 10th Division Lieutenant Rangiku Matsumoto observes that Hinamori looks awful and inquires if she has calmed down from earlier.

Though Hinamori meekly apologizes for causing her trouble as well, Rangiku dismisses this because she could not do anything either.
