is bleach episode 293 filler?

Lieutenants Izuru Kira and Tetsuzaemon Iba, commenting on the strength of the Reiatsu emanating from the captains and Visored, wonder if Lieutenants Momo Hinamori and Rangiku Matsumoto will be alright being around such a huge amount of Reiatsu. Kira wonders if the strength of the captains and Visored will be enough to defeat Aizen.

Aizen asks Captain Tōshirō Hitsugaya if right now he is thinking, because he has so much hatred against him, Hitsugaya is not worthy of being a captain. Hitsugaya tells him he is correct in thinking that, but he does not care because he is willing to lose his position in order to kill him.
