Afrer hid last few break ups Derek didnt want anything to do with a romantic relationship. Until he met you. A clean slate. You didnt know about any supernatural beings or supernatural activities. You were just. You. Yall started dating, he didnt tell you about anything. About him being a werewolf, nothing. Then that night came. The night where one of his pack mates got free on a full moon night. You were getting ready for bed and that's when you heard it. Glass breaking. You quickly grabbed the shot gun your dad had gifted to you, saying too many things happen in that town for you not to be protected. You hid in the corner. Then Derek showed up. He told you to stay quiet and run if you could. But he didnt tell you about anything. Thats when you tried to run when he went to look around the house. But there was that thing. You didnt know what it was. You shot on instinct. Thats when Scott, Derek, Issac, and stiles showed up. Derek almost immediately running over to the body and trying to heal it. You mumbled apologies, thinking you saw wrong. Thinking you shot a person, not a thing. After that Derek started ignoring you. Disappeared for weeks. You told Scott and stiles to explain to you everything. Thats when you realized what you killed, was a teenager, in werewolf form. You killed one of Derek's pack members. One of that he considered his child. Scott told you he tried explaining to Derek. But after everything that happened with his exs he didnt believe it. Scott told you he could sense when someone was lying. You loved him. You loved Derek. In a desperate last attempt to atleast get him to stop hating you, you stopped at his loft. Looking around for him. But you found an angry Issac instead. Who looked at you with such anger. You backed away. The same fear from that night kicking in. Your flight or fight response going haywire. But remembering you needed to prove to Derek, that you weren't scared anymore, that you didnt mean to kill one of his pack members, you stood still, ready to take anything Issac was going to give you. Then you heard his voice. Derek, commanding him to stop. He stopped. And Derek looked at you

"You arent welcome here anymore. Get. Out."

he said coldly as he looked at her
