Derek's Watching Me

-Read First Please- Derek has been obsessed with Casey (whose dating Sam) and he basically starts stalking her. Casey is getting freaked out by Derek's behavior but slightly ignores it hoping he'll just move on but Derek over steps his boundaries when he gets into a fight with Sam and ends up killing him. Casey is thinks it was just a freak accident until she starts adding up derek's strange behavior and decides to fight back against Derek. This was my first time using split so I hope it turned out okay and sorry for the very confusing plot line and I know very AU. I felt like trying something new :)Another thing When Casey walks into derek's room she's seeing all these pictures of her which are kinda stalkerish.. Song: "Haunted" by Evanescence I DO NOT OWN LIFE WITH DEREK :P
