is bleach episode 192 filler?

Nnoitra Gilga asks Orihime Inoue and Ichigo Kurosaki if they thought that Nel was harmless and tells them that she has deceived them, reiterating that she was an Espada. Nel denies that she was an Espada, prompting Nnoitra to ask if she has lost her memory, which she also denies.

When she denies deceiving Ichigo and Orihime, Nnoitra asks why she returned to Las Noches, inquiring if she intended to finish their previous fight. Nel tells him that she was simply having fun, recalling her time with Ichigo.
