>>79631566In the original comics, beast boy is a total edge lord, and it is ROBIN that is the laid back, humor dispensing one. That's why all the girls on the team wanted to be his cock sleeve.
Raven is the definition of tryhard edge lord, and Beast Boy gets Robin's advice on how to get into her pants/under her cloak. Because BB has no personality and no understanding of human relationships, thanks to being a super weapon on Doom Squad for his entire life prior to ending up on the TT squad.
Robin only does the romance two step with Wonder Girl and a bit of flirting on with the other girls before he goes full obsessed monogamous for Starfire in the comics. That leaves the rest of the girls taking whatever they can find. That means BB, Cyborg (despite his steady girlfriend), Aqualad, Speedy, and all the rest of the boys in the various branches of TT. Because, you know, they were teenagers, and the only thing teenagers care about is trying to get it on, one way or the other.
