Despite breaking free of his bonds, Batman is still weak from the Scarecrow's Fear Toxin. Still, his outrage fuels him, and he leaps onto his enemy. Unfortunately, this move inadvertently causes Scarecrow's scythe to ham sharply into his shoulder-blade, and break off. This gives Scarecrow the advantage, and so Batman takes a desperate measure, firing his tensile grappling line up and through the soft tissue under Scarecrow's jaw, and into the ceiling. When the time for the Gotham City Christmas Parade comes, Scarecrow infiltrates it with a small blimp, and releases fear toxin into the streets.
