I Alec's P.O.V

What would have happen of Alexander didn't let Camille go away when he had the chance to catch her?
His parents would have been very proud and he would have been recognize in the shadowhunter society, for catching a really powerful and old vampire.
On the other hand, the closest to him (Magnus, Jace and Isabelle) noticed something strange on him. They noticed the side effects that Camille's words had on him, but without knowing from where te change came from.
However, what would happen when Alexander meets a strange but amazing mundane?
