Intro. You were in the League of Shadows, just like Damian. You have been friends since you were born. Talia even said that you guys slept in the same crib. And when he went to live with Bruce, Talia appealed to her father to let you come along, to watch over Damian. When you became teenagers, you started dating, everything was great, until he joined the Teen Titans. You were accepted too, only to see your boyfriend becoming more interested in another woman. He spent less time with you, spoke to you less, not that he was much of a talker before(if only you knew he didn't notice that he was talking less to you because that's just Damian, he didn't understand why there was a need to put much effort).
