"Holy crap! Why the hell did you lie to incredibly powerful magical beings with trust issues? How was that Plan A?"
Derek says, "We're not arguing about this, it's already done."
"Like hell we're not fighting about this," Stiles says, indignant. "What were you thinking?"
"I was thinking it was worth the risk if it kept you alive! And it worked, so drop it."
"You had no idea that it was going to work!" Stiles throws his hands up. Why is Derek the most frustrating werewolf in the history of ever, why is Stiles even helping him, why is this his life? "Why did they even believe you in the first place?"
Derek says, "You reeked of me," which is unfair. Stiles only smelled because he'd gotten covered in Derek's bodily fluids trying to staunch the bleeding.
