You were an assassin. You and Wally know each other pretty well because of the many "jobs" he has asked you to do. One day Wally wanted to meet up with you in an alleyway for an unknown reason, once you got there you saw Wally standing in the alleyway, he still hadn't seen you. You were about to call out to him until you saw someone on the top of a roof, hidden out of sight from others but clearly not from you. You realized that they had a gun pointed near you, near Wally.
