Yeah, Nightwing is Robin. 당신 see, in the comics, Dick Grayson, the first Robin, after joining the Teen Titans and facing The Judas Contract, in an attempt to distance himself from Batman, dawned his own new identity; Nightwing. Since the series jumped ahead 5 years, similar to when the comics skipped one 년 after Infinite Crisis, a grown-up Robin emerges as Nightwing (following the flow of the comics). Hope that helps
Dick Grayson is Robin in YJ:I. There is this whole complicated thing about how Dick becomes Nightwing and is replaced 의해 Jason Todd, who dies (in the sacred hall of dead 히어로즈 thing in episode 9) and is then replaced again 의해 Tim Drake, the Robin in the new show. There are actually 5-6 Robins in total (not sure). I don't know if they will have all of them though... that's all I know. :)
