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 প্রদর্শনী 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 প্রদর্শনী are a completly different team than the team BB and রশ্মি are in when they finnaly get togather. দ্বারা 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 প্রদর্শনী never gets as far as the comic বই 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."
