i don't yet! i'm just thinking she was a foster kid who bounced around homes a lot, then discovered she was an alien with powers which is the least fun way to get through puberty when you already felt like a figurative alien. i was hoping she could either have joined a teen titan thing when she was younger, tried to step back from heroism, and then got pulled back in all over again as an adult. but i'm very flexible so i can adjust and make it fit!
