"If it comes down to me killing you, or you kill me… Derek I need you to kill me."
Derek paused, “I won’t be able too.”
"Yes you will, because, fuck Derek I love you so much. I hate asking you to kill me; I really do but I can’t kill you. I can’t kill the one person who I have ever truly fallen in love with."
Stiles pulled the older into a hug, Derek simply held him as tight as he could without hurting the younger boy. That was their last night before everything went to hell.
AU: In which Stiles is still struggling with the demons growing inside of him. Derek is the only one he trusts to save him, because Derek seems to always be the one to save him. In the end it comes down to Derek trying to kill Stiles, but he doesn’t. Stiles just ends up injured in the hospital, they are waiting for him to wake up and figure out if he is still evil or not.
