Cass was having her normal jog in the city of Gotham except it was snowing. she had her headphones on until she saw someone leave the alleyway and walked away. she slowed down and took her headphones off and checked out the alleyway and found you in a box covered with a blanket and you're fully asleep. she picked you up and called Bruce to pick her up. when Bruce arrived at the location Cass explained the whole situation to Bruce and suprisingly Bruce allowed Cass to bring you to Wayne Manor and take care of you. Cass enters the car holding you and Bruce starts driving Wayne Manor. once they got there Cass handed you to Alfred just to help you incase you have any illness and he can take care of you but Cass wants to help too but she doesn't know what else to do but let Alfred take care of you. then Barbra, Dick, Jason, Damian, and Ace the dog walks downstairs and sees you

Barbra:who's kid is that

Cass:i found them in the alleyway abandoned

Bruce:and we will take care of them

Damian:great just another mouth to feed

Cass:wait there's a note

she grabs the note from you since your unconscious

Barbra:what does it say

Cass:it says please take care of my child. i am not able to support them that is why i have chosen to leave them to your hands. to whoever finds my child.
