You still weren't yourself after the Nogitsune incident. You saw Derek Hale burn to death, just like everyone else in the pack. But you just couldn't accept his death, it was hard to believe, when he was the one who tricks death more than once. So you turned the forest upside down until you found a wolf, it's take weeks but you find it. A wolf whose black fur looked like it had been burnt... if it wasn't Derek, then it's the first wolf of the forest in about eighty years. But you're sure it's the werewolf you search. Your friend, person who you love, who's sacrificed himself for he's family, for he's son Eli.
You carried the wolf you found to your car and placed it in the back seat. It was an extremely difficult job, but this wolf, real animal or werewolf, needed help. After covering wolf with a blanket, you started the car. You didn't expect the wolf to turn into a human halfway through. “What the hell?”, Derek looking at you in the rearview mirror. Most likely the last thing he remembered was his death. At least you were right about Derek not dead.
