You and your siblings (Dick, Jason, Tim, Cassandra, Duke, and Damian) were all minding your own businesses, being the chaotic Wayne/bat kids you all are while Stephanie, Barbara, and Barbara's pick me cousin Emma were being chaotic as well, but Emma was being annoying. That was when the news cut on.
News reporter: Breaking news, all the famous Gotham villains are attacking Gotham. Commissioner Gordon has asked that all citizens to stay in your house with all doors locked
It shows the villains you all encountered, they were either robbing banks, causing a shooting, or stuff. The police were trying to stop it, and the Justice League was getting citizens to safety
You and your siblings looked rather shocked by what was happening, wondering why all the villains are working together. Emma was whining about something, but none of you were paying any attention to her.
