is bleach episode 66 filler?

At nighttime in the Urahara Shop, Tessai Tsukabishi pours a cup of tea for himself and Kisuke Urahara as they sit together at a table before drinking from their cups, leaning back, and sighing in unison. Suddenly, a commotion from outside startles Urahara, causing his hat to briefly fly off his head and his tea to spill from his cup when he jumps slightly, as Ichigo Kurosaki barges in with Kon, inhabiting his body, under his arm and Uryū Ishida following him alongside 6th Division Lieutenant Renji Abarai.
