"It's been six years, Derek. Six years I was left in a bed. Healing myself one bit at a time, one cell at a time. Constantly working against the burns, against the pain. And through it all, I listened to the screams in my head. I listened to your tiny niece beg me to save her. I begged whoever was outside that window to let them out. I told them I would take the fire, if they would save the children. Do you know what I heard, Derek? Laughter. They laughed. I can not let them do this to others, Derek."

Her eyes narrowed. "You turned your back on me, Derek. He hasn't been your guardian for yours. You said it. Three years on your own and you left me. You will not leave now," she growled, eyes glowing red. "You'll be my beta, Derek, as you are. You'll help me train Scott and Stiles. We will find the hunter behind it. All of them."
