(I'm just getting back into DC, specially Teen Titans, so don't flame me if this info is incorrect.)
This is the infamous duo, Nightwing/Robin and Starfire. They have been together in different shows and comics. They have a intimate/romantic relationship with eachtother, and are still part of the Titans in this point in time. The Titans in this version consist of Nightwing, Starfire, Raven, Beast Boy, and Cyborg. Beast Boy and Raven are also another infamous couple.
