Two Wrongs Make a Right

Interruptions

Derek and Stiles looked at each other in confusion from the words that had just left Scott's lips. "You think it was Derek?"

"No, Stiles, I know it was him."

"Bullshit." Derek said under his breath, careful to not speak too loud that Scott would here him through the speaker phone.

"What makes you think it was Derek?" Stiles asked, worry in his voice as he looked at Derek who was clearly annoyed. Stiles put his hand on Derek's thigh in attempt to calm him down. It must have been working because that's when Derek put his hand on top of Stiles' and gently stroked it with his thumb.

"There's scratch marks and bite marks on either half of the body."

"Scott, I think you're missing the big picture."

"What do you mean? What bigger picture?"

"THE GIRL WAS CUT IN HALF DUMMY, OF COURSE SHE HAD A SCRATCH OR 2!" Stiles sort of shouted sarcastically into the phone which made Derek chuckle a little.

"Stiles, don't get sarcy with my now. This is serious." Derek was still chuckling a bit which earned a small slap from Stiles. This didn't impress Derek, so he thought it'd be funny to shove Stiles off the sofa.

"Hey!" Stiles whined as he hit the floor, before they both burst out in laughter.

"Stiles, who are you with?"

Oh crap. Stiles thought as he shared a look of worry with Derek. He couldn't tell Scott he was with Derek. He would hate him.

"He's with me." Derek said into the speaker phone. There was a long pause.

"Stiles, get away from him! He killed that girl!"

"That girl happens to be my sister, Laura Hale. So you really think I'd kill part of the little amount of family I have left?" He said in a smooth voice.

"He has a point Scott, he doesn't have much family left. Why would he want to reduce that down further?" Stiles explained as he traced circles with his finger on Derek's thigh, relaxing both of them.

"How do you explain the claw and teeth marks then, smart ass?"

"Get your head out of your ass, Scott." Derek said, annoyance filled his voice. "You and I aren't the only werewolves in Beacon Hills. Don't forget there's the alpha. You know, the one that bit you. Funnily enough he's a werewolf, too."

"I don't believe all this alpha stuff you're telling me. Stiles, I'm coming to get you. You're not safe with him."

"Scott, I trust him." Stiles said quietly. "I know he won't hurt me and I know he didn't kill his sister. Out there, somewhere, there is an alpha werewolf that is turning people and killing people. That werewolf isn't Derek, I know it."

"How do you know he isn't the alpha? He could be lying to us."

"Because his wolf eyes are blue." He said staring into Derek's eyes that were starting to glow blue, clearly that was due to Scott annoying the shit out of him. Luckily, Stiles' touch soothed him enough to make his eyes shift back to their regular green colour.

"What does the colour of his eyes have anything to do with this?"

"You're new to this werewolf stuff, Scott. Different colours have different meanings. Yours are gold because you've never killed, Derek's are blue because he has killed-"

"It was an accident and when I was 15 before you say anything Scott!" Derek looked at Stiles who looked curious. "I'll tell you later." He whispered to him.
