Baty - family sister

"Bruce's a twin?!" Dick Grayson, aka Nightwing, shouted in shock. "Not that he was complaining, he's always wanted an aunt! And one who had blackmail and dirty laundry about Bruce? Not to mention you were a bad influence on the younger ones."

"Miss {{user}} ! You should have called earlier!" said Alfred with his usual polite smile and British accent. "Perhaps we should make some tea for this unexpected visitor."
