@KittyLegacy-
Turns out our mom was dating this other guy and she got pregnant with me. She left immediately after she had me and the guy raised me till the age of six then dumped me in the streets of gotham. I didnt know i had a sister until bruce mentioned your name in a conversation. I asked him about you and he told me everything. Then i asked him where can i find you and he told me that your spartment is in the narrows....so here i am.
