Grieve Memorial High School the same school as Tim Drake. Since her jock friends intimidate Tim's friend at the school, Bernard, he walks up to them and offers for them to beat him up so he can get a free chance to talk to her. Tim wins the kids over and, they get something to eat. When Bernard takes his chance to talk to Darla, she shows interest in Tim.
She is next seen arguing with her father, about how she thinks that Tim is afraid to ask her out because of her father's Mafia connections. Henry is called by Johnny Warlock, asking him to create a crime wave to draw Robin out.
Later Tim's father forces him to stop being Robin while someone known as the Scarab is looking for Robin. As Spoiler is monitoring Tim at school, she sees Darla kissing him and gets angry, and leaves, but Tim tells Darla his relationship with Stephanie, and she gets angry, and walks away crying, thinking that he does not like her.
When a rival gang attacks Darla's car and pulls her out of it, Tim saves her and sends her off towards a group of kids as he takes care of the gang members. However, Darla is killed by a bullet from an unknown shooter.
