"So, you think he was just sleepwalking? Or is there something more to it?"
Derek turns to Aiden with a patronizing stare. "In this town there's always something more," he answers wisely.
"What if I told you I know something more? I kind of overheard," Aiden pauses. "Well," he acknowledges. "I listened in on Stiles talking to Scott. How he thinks he was the one who wrote that message in the Chemistry room. The message telling Barrow to kill Kira."
Aiden glances at Derek with a meaningful look. Derek usually wants to punch off whatever stupid expression appears on Aiden's face. Whether it is full of smugness, arrogance, or simply a patronizing smile. Today is no exception.
"You think Stiles, skinny, defenseless, Stiles is the Nogitsune? A powerful, dark spirit?" If Stiles is a dark spirit than Derek is a gold looting leprechaun. Seriously, that boy couldn't hurt a baby panda. It isn't just about muscle mass either, it's his soul. Stiles has one of the purest hearts that Derek has ever seen. The kid is absolutely unfathomable in his devotion to Scott, even when it means putting himself in harm's way. The word no doesn't even seem to be in Stiles' vocabulary. Tell him there's something he can't do and he finds a way to prove you wrong. Derek has learned early on never to underestimate him. So yes, Stiles Stilinski maybe a lot of things, but dark is not one of them.
"I'm not the only one thinking it. I'm just the only one saying it," Aiden defends.
It's like this idiot has never even met Stiles. Seriously, does Derek really have to share a pack with this moron? Derek has more muscle definition in his pinky than Stiles has in his whole body. A Twinkie has more filling than Stiles. Okay, so maybe the reason Stiles couldn't be dark had a tiny bit to do with muscle mass.
"This thing wants to possess someone and chooses Stiles?" The idea was laughable. "Why wouldn't it take someone bigger, stronger? Someone with a little more power? Someone who doesn't wear t-shirts with ridiculous phrases on them? Who can eat a bag of curly fries without dropping half of them? That can go five minutes without making a sarcastic comment? Why would a demon possess a person who is completely helpless, and selfless, and loyal, and good?"
Derek finally breaks off from his tangent to find Aiden with a disgustingly arrogant grin on his face.
"What," he asks, already regretting it.
"Someone has the hot's for Stilinski," Aiden teases.
"I hate you so much," Derek says.
