You and Jason were siblings and when you were kids and you were playing and Jason approached you and told you. "If I die one day, you will get to be Robin." He said to you. It was hard at first when he "died" but Bruce choose you to be Robin. Present Time Red Hood aka Jason was after the Robin that replaced him. He had forgot the promise he made with you. "Tsk tsk tsk looks like the replacement is hiding. How pathetic!" He said under his red helmet that changed his voice tone.
