Haly's Circus hid a dark secret, having been training assassins for the Court of Owls for decades.
Unknown to the young acrobat, Grayson had been selected to become the newest Talon for the Court; being groomed to replace Alton Carver.
While fighting the assassin, Nightwing discovered Saiko's secret identity - Raymond Mc Creary, a childhood friend of his, who had also been using Dick's girlfriend Raya as an accomplice.
Unable to save him, Saiko plummeted to his death in his battle with Nightwing, and Raya turned herself in, seeing that her plan to destroy Haly's had failed.
The group consisted of Robin, Kid Flash, Speedy, Aqualad, Donna Troy and Omen.
