I love this coming full circle with the werewolf mythology stuff. Originally Stiles thought silver would harm them but Derek threw that theory out the window. And now, with finally addressing the long-legacied ancient Hunter family's last name "Argent". Obviously Silver can kill werewolves. Just not the kind of silver we were all thinking of. When they first mentioned the family's name I thought it was just a clever reference but now that we know how old the family is and how long they have been in the business I think they might have just been the ones to inspire that aspect of werewolf mythology.
@George- His Uncle was damaged badly in the fire and it took years for him to slowly heal his body and his mind. Why is he the Alpha? Were you not paying attention? He admitted killing Derek's sister who was an Alpha back in town investigating the fire. He thus became an Alpha. He also stated that becoming an Alpha greatly sped up the healing process of his body. You can only be confused if your not actually paying attention because his Uncle's monologue gave you ALL the information.
