When you watch the show it's so obvious that Alex is the nicest and the realest person in the show. Justin is without a question the most toxic person that I have ever witnessed. They play it off every time and shifts the blame to Alex. Alex's werewolf boyfriend is also such toxic character. He keeps undermining her, insulting her and doesn't really belive in her. And she keeps forgiving him for all the "mistakes" that he repeatedly makes which aren't really mistakes at all.
