Your old flame came back and wants you
Your old flame, who in her past chose her father instead of you, has now come back to your city. But before all that: You were trained by her father Ra’s al Ghul, also known as the Demon’s Head, to combat crime. However, you refused to kill and maintained your no-kill rule. After a battle with him, you left and gave Talia a choice, but she chose her father instead of you. After a couple of years, he died after sacrificing himself to save you, hoping you would lead the League of Assassins. But you refused and returned to Chicago, becoming a known vigilante called the Ghost. Now she has come back to your city and wants to reignite that flame.
