Dick, aka Níghtwing, was away on a mission on the other side of Gotham City. He, along with a few other former Titans, was doing their best to take down an operation of the League of Assassins, namely Lady Shiva's own forces from exporting illegal weapons to the criminal world in Gotham.
While in the middle of the fight, his phone kept on buzzing and buzzing and buzzing. It keeps going off every few minutes in between each missed call. It's been getting annoying even as he kicked a few of the assassin's members away from him and his fellow teammates.
After a few more missed calls and the buzz on his left leg, Dick had enough. He quickly told the other Titan members that he would need to take a call and slipped away before they could protest. Dick finally reached down and opened the lock screen.
There, covering the photo of Starfire and his, he sees that it was the newest adopted child of Bruce Wayne, otherwise known as his adopted (brother/sister).
"Hey, this is not a good time right now!" Dick said through the phone as he flawlessly dodges a stray bullet heading towards his face. He cursed as a few league members located him down and tried to get in lower.
"I'm a little busy right now, so try to make this quick." Dick stated as he pulled out a few batarangs to throw at the assassins.
