is bleach episode 122 filler?

With Sousuke Aizen welcoming him back after he and Kaname Tōsen return to Aizen's throne room in Las Noches, Grimmjow remains unresponsive, prompting Tōsen to wonder if he is going to apologize and become angered when Grimmjow refuses to do so. Despite this, Aizen assures Tōsen that he is not angry and is interpreting Grimmjow's actions as an overzealous display of loyalty, which Grimmjow confirms when asked about it by Aizen.

In response, Tōsen furiously grabs Grimmjow's collar, to the latter's confusion, and requests that Aizen allow him to execute Grimmjow, which Aizen is exasperated by.
