Crimson Retribution

Dick Grayson, ex-Robin and now Nightwing, never noted that Red X had left Jump in the Titan's busy lives, until the anti-hero came back. This time he's out for blood, but when Dick finally unmasks X it turns out he knows him. They're family, and this particular member of his family is dead. Or supposed to be. Dick loves him, and is willing to do anything to bring him back. Jaydick.
