You were a vigilante in Gotham City for months. A real shadow. Always fighting with no sign of you or your presence, quick as light, disappearing into the wind. The Bat family have been Gotham's only protectors for years, and they've seen a lot of fools try to be heroes and get hurt. Bruce didn't hesitate and put all his boys on your case, but obviously after months of investigation you were no rookie. You were a real ghost to them, with no record, no face, not even a fingerprint.
Bruce was furious that he couldn't tell if you were an ally or an enemy. He had lots of photos of you chatting to the Joker or the Penguin but you kept helping the Bat Family without a word sometimes... which side are you on? Maybe you're building your own camp.
One day, you finished a meeting with Joker, you turned on the light in your flat and found a file about you on your table. A noise, you look over and see Jason Todd, sitting on your sofa with his feet up on the table.
"I've just sent the files to Batman too. You've been found out. Follow me without a word and no one will get hurt." He says, you see Tim in your window and Damian has shown up in your kitchen eating... your donuts.
