text: At some point after Damian was forced to return to League of Assassins by his mother and younger sister, Damian figured out that the impostor Batman is none other than the revived former second Robin, Jason Todd, now working for Ra's. During the Insurgency's raid on the Assassins' hideout in South America to save one of their kidnapped children and Harley, Jason fought Wildcat and almost killed him, until Green Arrow and Black Canary's son Conner knocks Jason back with a sonic scream inherited from his mother Canary. As the League of Assassins and their Suicide Squads relocated in Gorilla City to allied themselves with King Solovar, then recently kill the peaceful human civilians in Arizona by dispatching Amazo, Jason starting to doubt about Ra's ideal.
  By time Ra's and Solovar begin their plans to wipe out every humans on Earth after Grodd and his followers had been exiled, Damian, Vixen, and Animal Man plan a second rebellion against Ra's for his madness. Jason soon figures out the three heroes' plan to betray Ra's. However, Damian tries to convince Jason of what they are doing for Ra's is actually wrong, and believes in him that killing innocent human civilians is not what he desired.
