Stiles and Stuart are identical twins. They have completely different personalities. Their younger sister, Cassandra Stilinski, has always been the outcast. Her brothers are too distracted by keeping their own secrets to notice a sudden difference in Casey. They finally star to notice, but could they be too late. Allison is dead sorry it's for the story line later on, and Jackson is gone for the purpose of the story line. I don not own any of the Teen Wolf characters. I only own the characters that I created (Casey Stilinksi)
