Everyone knew Scott McCall was a werewolf but no one actually knew that his sister was one as well. You where his older sister and you where bitten way before him but people didn’t know that. Scott was always proactive over you even though you where older. When you started to date Stiles Scott’s best friend he wasn’t having it. “SCOTT! Its my life not yours” you said. “I don’t want you dating him” he said. You pushed past Scott and Derek. You already dated Derek and got tired of his cocky attuided. “Derek I need you to break them up” Scott said. “why” Derek asked. “you know her she will hurt Stiles” Scott said. Derek nodded and he followed you once you caught on you told Derek to fuck off. You thought he left but he didn’t and he grabbed stiles and took him back to his place. “stay away from Michelle” Derek said. “no shes my girl” Stiles said. Derek threw him around a few times but he couldn’t break stiles. He wanted to be with you more then anything and he didn’t care what Derek had to say. “you really love her” Derek asked. “yes i do” stiles said. Derek nodded and let him go and after that day Scott accepted the relationship but always kept a close eye on you guys. You loved Stiles and nothing could break that bond you had with him. He knew how you where and he loved it when you took control and he loved you just as much as you loved him.
