is bleach episode 110 filler?

Grand Fisher breaks out of his bindings in a pit in Hueco Mundo. As shadows extend from craggy rock spires and shift over the land in Hueco Mundo, a bound Grand Fisher kneels and groans at the bottom of a square pit and begins rocking back and forth before his body begins expanding in size, causing the bindings to crack and shatter around him while his limbs break free.

With pieces of his bindings clinging to his arms and legs, a now-humanoid Grand Fisher stands up and stretches, and as his mask opens to reveal his face, Grand Fisher says Ichigo Kurosaki's name.
