Heartless has an extra-giant jar that has Blockbuster's name on it, but as a man of refined taste, Heartless doesn't just collect any type of heart...he waits for someone to experience a specific emotion in particular before taking it all away from them and adding it into his collection. Does Nightwing have what it takes to save the life of the very man who s been trying to take everything away from Dick Grayson, including his life?
