Warning! Spoilers ahead for Nightwing #85
DC Comics just saw Nightwing prove that Barbara Gordon's Batgirl has reclaimed her problematic role and trauma from The Killing Joke. While the classic Batman story from Alan Moore and Brian Bolland sees Barbara's Gordon undergoing a horrifying experience at the hands of the Joker where she was shot in the spine and paralyzed, it wasn't done because Barbara was the focal point of the narrative. Instead, Barbara's pain and suffering was simply a tool Joker exploited to get to her father, Jim Gordon, Gotham City's police commissioner. That being said, Dick Grayson reminds Barbara in the latest issue of Nightwing that she's since overcome her trauma in some pretty dynamic ways both as Batgirl and as Oracle.
Currently, in Nightwing, from writer Tom Taylor and artist Bruno Redondo, Dick Grayson answered the call to come to Batgirl's aid in Gotham as the city has been completely overrun by Scarecrow and the Magistrate during DC's Fear State event. However, Barbara's call for help turned out to be a trap set by the new anti-Oracle known as Seer. Seer has corrupted Oracle's systems in Nightwing #85, motivating Barbara to destroy her entire Oracle network in a bid to slow the new villain down.
After Dick helps Barbara destroy her base of operations within Gotham's clocktower, Batgirl admits that she knows exactly what it feels like to be trapped and harmed for the sake of making someone else hurt. Just as Nightwing was lured by Seer in an attempt to make Batgirl suffer, Barbara was shot by the Joker in an effort to make her father go insane in The Killing Joke. The pain and trauma Barbara endured wasn't even about her and was simply a tool to make Jim Gordon hurt. However, Dick Grayson proves to Barbara that she's done a lot of good, reminding her that she's taken large strides to make it a part of her story as Oracle and Batgirl (creating tech implanted in her spine to help her walk again).
Nightwing definitely makes a great point. Barbara didn't wallow in her pain or let her trauma get the best of her. Despite her problematic role in The Killing Joke, where she was gravely injured all for the sake of someone else's story, she chose to reclaim her story as her own. Determining to use her talents to become Oracle, despite what was done to her, while also finding a way to become Batgirl once more, Barbara Gordon has done some incredible things and has saved both Gotham and the world at large on multiple occasions in spite of the Joker.
All in all, this is a poignant moment between Dick Grayson and Barbara Gordon, and it's a great reminder for Barbara that she's worked hard to prevent her trauma from being just a part of someone else's narrative. It's since become a foundational and much more significant piece of her own story, which is an impressive character development that has evolved over the years since The Killing Joke. In any case, Batgirl has returned with the corruption of Oracle in Gotham, resulting in Barbara working side by side with Nightwing once again as they fight to save Gotham during DC's Fear State.
