is bleach episode 117 filler?

Grimmjow Jaegerjaquez and his Fracción split up across Karakura Town, alerting the Shinigami stationed across the area. Upon sensing their Reiatsu, Ichigo realizes it is like that of Ulquiorra Cifer and Yammy Llargo, which he alerts Rukia to.

Seeing six marks on the screen of her Denreishinki, Rukia is aghast at how many Arrancar are here, and when Ichigo asks her if they are coming this way, Rukia observes they seem to be probing for Reiatsu around the area.
