Eagle-eyed fans are still discovering new secrets hidden within Batman v Superman: Dawn of Justice thanks to the film's recent Blu-ray release, and this latest Easter egg may point toward a fan-favorite Batman character being a part of the DC cinematic universe.

As spotted by one Reddit user, a segment from the film in which Batman is using a computer in the Batcave is the key. In the bottom left of the computer screen, the words "Oracle Network" can be seen, followed by the phrase "Link Established." It seems Bruce is connecting to some powerful, external network in order to conduct his work.

Comic fans likely know what this means. Oracle, of course, is the hacker alter-ego of Barbara Gordon, who, in the comics, regularly helps Batman in his various investigations. Barbara, at one time Batgirl, becomes the wheelchair-bound Oracle after being crippled by the Joker in the events of Batman: The Killing Joke.

If the Oracle Network in the film is indeed the creation of Barbara, that means the events of Batman: The Killing Joke (or a similar scenario) must have already happened in the DC film universe. It has already been confirmed that the Joker killed Jason Todd (one of the many Robins) prior to the events of Batman v Superman, so it's not too much of a stretch to assume that Joker may have also maimed one of Batman's other close allies.

It's also worth pointing out that Commissioner Jim Gordon, Barbara's father, will be appearing in Zack Snyder's upcoming Justice League film. That movie might be the perfect time to introduce the character to audiences. After all, with Superman gone and the threat of Darkseid's followers looming over the Justice League, Batman will need all the allies he can get if humanity is to prevail.

For many fans, it would be a long time coming. Barbara Gordon was long-rumored to appear in Batman v Superman, thought to be played by Jena Malone. When her character was cut from the theatrical version of the film, fans waited in anticipation for the extended ultimate edition of the movie to arrive in order to confirm her role, but it turns out Malone played a S.T.A.R.S. lab scientist, not Barbara Gordon.

Given the upcoming appearance of her father and this Easter egg, it seems like a safe bet to assume that fans will get to meet the cinematic universe version of Barbara Gordon sooner or later. The question now is when?
