is bleach episode 320 filler?

At the Urahara Shop, Ichigo Kurosaki, Uryū Ishida and Yasutora Sado are sitting at a table silently, as Orihime Inoue assesses the condition of Nozomi. She stirs in her sleep, much to Orihime's surprise, as Uryū informs Nozomi of her whereabouts.

He reassures her, stating that they are in a safe location. As Nozomi attempts to get up, Orihime tells her not to over-exert herself.

Kon then enters and asks if she's alright. Nozomi wonders what Kon is, to which he asks her why Kagerōza Inaba and the others were pursuing her.

She calls him lame, which provokes Kon into revealing his true identity as a Mod-Soul.
