Robin has a good connection to Raven, they have a very good friendship and respect each other. Robin and Raven have a mental bond together which allows Robin to know when Raven is troubled such as the world ending. They have a close friendship due to similar personalities and instincts. Robin was also able to give Raven enough hope and courage for her to defeat Trigon, and he told Raven that she was the most hopeful person he knew. It is obvious Robin cares a lot about Raven, as he willingly traveled into a literal "Hell" created by Trigon in order to save her. The two seemed to get along well from the beginning. Robin is the only one serious enough to understand her and Robin has been to her mind. Robin helps her out whenever he can especially when it comes down to Trigon or Slade or both. When they first met, Raven told Robin, Beast Boy and Cyborg: "If you knew what I really am, you wouldn't want me around." Robin responded by saying "I know enough", implying that he didn't care what Raven was or if she was different and knew that she wasn't evil or bad. In the end, both of them consider each other as sibling figures, like brother and sister.
