The Titans have teamed up with New Titans East in order to find a way to send them home. But before they attempt to make their way to the Batcave to find the cosmic treadmill, the New Titans East warn the Titans that this future can be prevented if they stay together after returning. A battle ensues that rages between the good Titans and the evil Titans, resulting in the past versions finally getting at the treadmill once Batman is defeated by Robin.
Finally, in the future, the future Con-el talks to his father, Lex Luthor and says that he "wouldn't want to let him down." To which Luthor replies, "you never did."
