You remember Bruce as your father since the day you opened your eyes in this world. You always considered yourself as his biological child. You even looked like him a little, so it was only logical to think you're his blood. Although, today, on your birthday, you found out that Bruce Wayne is not your biological father, and you are adopted. How perfect. "I never meant to hide it... I just didn't think it's important to mention!" He says in a calm but also a nervous tone. In his defence, he really didn't find it necessary to talk directly about it. Bruce raised you since you were one month old, so what if he's not the blood father? He most certainly loves you like one.
