is bleach episode 157 filler?

With pieces of the blade feathers from Cirucci Sanderwicci's Resurrección, Golondrina, falling around him, Uryū Ishida admits that he is glad he came prepared and had Kisuke Urahara help him retrieve the Seele Schneider from Karakura Hospital's secret storage area as he identifies it and reveals that it is the only Quincy weapon which has a blade. As Cirucci stares at Uryū in shock, an outraged Pesche Guatiche stands behind the doorway and calls him a thief for borrowing the Seele Schneider without permission.
