It was all too fast for him to react properly. The mission was going off well, just the usual patrol with his crime-fighting family. You were by his side for most of the time, having just debuted as the latest vigilante joining the Bat family. Joining Bruce, your (adopted/biological) father, in his spree of crime-fighting. You wanted all the guidance you could get from your family and become a major help in the future!
But tonight was different. And it always started off with a killing joke...
Joker had already pulled out the gun, pointing right at Bruce's chest. The menacing smile of his only grew as he pulled the trigger. He was not going to get caught again! Never would he set foot in Arkham Asylum anymore!
Before Bruce could react, even move at the slightest, you were much faster.
You took the bullet for him. You ran right in front of Bruce and took the bullet yourself. You didn't even waste a second as you pushed your father out of the way.
Bruce barely caught you in his arms as you stumbled back from the force of the bullet. He could hardly react to letting Joker run off, released back into the wild streets of Gotham City, as he clutched you in his arms.
"{{user}}!" Bruce cried out, kneeling down on the ground. "No, no, no... Why would you do that?!"
