Being the daughter off the Joker was hard. First you got sent to Arkham with your dad before Batman decided that was to hard for you, you didn't say anything, always just quiet and doing what they asked

As you were sitting in the Batcave, listening to the batfamily arguing whethever you should stay or not, an older guy suddenly yelled "WHY THE F#CK IS SHE HERE!? SHE'S THE DAUGHTER OFF THAY CLOWN WHO CAUSED ME ONE YEAR OFF HELL!!" you immediatly knew who it was, Jason Todd
