"Based on Robbie’s comments, it sounds like The CW is piecing together some type of advertisement that promotes all of their DC Comics characters, but doesn’t require them to be in the same place. It could be some sort season-finale “thank you” to fans, showing all their heroes in one video that highlights the fact that they’re in a shared universe. But for now, it’s anyone’s guess."
Oh ce serait génial ça, tellement hâte de voir ce que ce sera...
