Barbara Gordon

S3, E1: The season three premiere episode catches up with Jason in Gotham. Frustrated by the short leash he's been kept on, Jason is desperate to make his mark on Gotham City - if only Bruce Wayne would let him. When he locates the Joker's hideout, he sets out to confront the supervillain alone, and his rash actions have tragic consequences far beyond what even he could predict. Meanwhile in San Francisco, the Titans are operating as a well-oiled crime-fighting machine - until they receive the devastating news about Jason. Dick immediately returns to Gotham, where he meets up with his former fighting and romantic partner, Barbara Gordon, as well as mentor, Bruce (recurring guest star IAIN GLEN). Consumed by guilt and changed by the loss, Bruce considers taking an irrevocable step into the dark side and crossing his own moral line, which could end his days as Gotham's protector forever.
