This was the part Stiles really didn't want to do. He didn't want to be the one to deliver the tough blow, but at the same time, there was just something inside him that wanted to give it a shot. He felt like he owed it to Derek, and he didn't even know why. He wasn't a wolf, he wasn't Derek's alpha. In fact, their prior interactions were almost completely based on Derek being a misery guts and Stiles constantly feeling like he was either getting on his nerves or getting in his way. But when he looked at Derek now, he just seemed to understand how scared and lonely he must be feeling.

"There was a fire. Started by Kate Argent... the Argents are hunters, Derek," he began to explain, lowering his gaze to the surface of his mug for a moment or two. "That's not something you're probably aware of, uh, at the age you are. But it's true. They're hunters, and she's one of the most vicious. She brought you back to this time because she knew you still trusted her and didn't know what she was. She basically played you, and used you for her bitch... again. She only ever used you to get information about your family, and then once she had, she burned your house down to kill them all. Your mother died, you were at school with Laura. Peter ended up in a coma. Laura was left the alpha, from what I have been told, and ultimately Peter, the power-whore, killed Laura to get that status. From there on, it just gets more messy, and more miserable. As did you. Miserable and vengeful. This you isn't the you we all know."
