Wayne Enterprises vowed to stay in Gotham City and help start 10,000 new small businesses. Mad Hatter teamed up with Narcosis temporarily and then took him down (so he could have his hat/cowl). He began releasing Narcosis' bliss gas across Gotham. Batman destroyed what he was using to release the gas and took down Tetch. Narcosis was believed dead in an ensuing fire. Oracle called in helicopters to burn away the gas.
