Stewart: Batgirl has really been put through the wringer in recent years – after being attacked and paralyzed by the Joker, her brother turning out to be a serial murderer, the trauma of her family breaking apart and the series of gruesome villains she’s had to contend with, we figured she deserved a break from all that.
Just prior to the start of our story she’s pushed to the breaking point and decides that she’s had it with misery and darkness and wants a change. She wants the opportunity to have some fun and live the life of a young, single girl in the city, so she packs up and moves to Burnside, the cool, trendy borough of Gotham, to focus on grad school.
