Bruce may not have been able to follow Zelriane's movements, but having fought him once, he was familiar with his tactics. The fact that the faster Order member took Jenso's back was hardly a surprise, and precious moments were not wasted collecting the sand Bruce had spread around the chamber beneath Jenso. 

Two arms of sand, identical to Bruce's, flew up just behind Jenso, golden Ki concentrating, folding over and humming in synchronized melody in each hand. In the right hand, Bruce's blade took form again and slashed upward, intention of severing Zelriane's hands clear. In the left hand, spiked chains materialized and erupted forward to embed themselves in Zelriane's torso.
