Is it due to the horrible circumstances that drew him to be Bruce Wayne’s ward, or is it because of the actual raising and upbringing? So a lot of the story’s about that, and a lot of the trajectory of the character has to do with that struggle."Here's a cool new Titans poster below:For more on Titans, check out how we think Jason Todd's inclusion could impact the series
