is bleach episode 208 filler?

Hiyori and Urahara head to the Nest of Maggots, and they arrive at the Second Division. Inside the barracks, one of the members of the Executive Militia tells Captain Yoruichi Shihōin that Urahara is waiting outside, claiming that he has already been given permission from Yoruichi.

Yoruichi tries to remember what Urahara came for, and casually says he can go do whatever he wants to. Suì-Fēng quickly objects, but Yoruichi tells her that she shouldn't worry about him.

The gate opens, and Urahara enters with Hiyori.
