To all the divas who are confused the black hair guy has MAJOR mommy issues cuz his mom forced him to act and be an alpha even thought HE IS A BETA. Flashforward to now his ex who is the doctor guy is exposing him to phermon therapy and alpha pheromones so that he can PRETEND to be an alpha and I think die to the constant exposure he is now albe to sense pheromones even tho he is a beta. This is also the reason why he has relationships with alphas to try and smell like them (the only way for him to be able to get him smelling like an alpha) to cover up his beta trait
