how come raven and beast boy have a sort of relationship in the comic books, but not in the t.v. show?

Because the tV mostrar is for smaller viewers aswell that is why robin and starfire didnt have much of a relationship until the movie

plus, the titans in the mostrar are a completly different team than the team BB and rayo, ray are in when they finnaly get togather. por then, raven has been reborn into a teenager again, making her bbs age. in the original(what the shows based on), BB was the jr.titan and Raven was older and kept to herself more.Plus Kid Flash kinda had a thing for raven. BB had a thing for "Goldie"(what he called Starfire):)

Because the TV mostrar never gets as far as the comic libros did. I wish it would but apparently the creators ran out of money and couldn't continue the show. Sad story, but as Raven once said, "We can't change the truth no matter how much we dislike it."
