Shinigami and Quincy, the Battle with Madness

Loly and Menoly continue to mistreat Orihime and Loly is about to finish her off when the wall shatters and who should enter but Grimmjow.
Meanwhile, Uryuu takes up the battle against the Fraccion of Szayel when his initial strike has no effect whatsoever on the Espada. Renji might be able to lend a helping hand but can the two hope to defeat Szayel when he can predict their every move?
