Stiles peaked into his dad's office to see that he was looking over a bunch of paperwork; he nodded to himself then turned back around to face Derek who seemed to be confused about what he was doing.
"My dad can't know you're here. He'll flip out, because in case you forgot, you were accused of murder not that long ago and that means my dad will not approve of us having a sleepover." Stiles explained in a whisper so that his dad wouldn't over hear his son talking to someone.
Derek rolled his eyes, "It's not a sleepover. I don't have sleepovers. I'm just making sure no one tries to kill you while you're asleep."
Stiles' lips twitched up into a smirk, "Oh, don't worry, Buddy. Having a sleepover does not make you look less masculine."
Derek let out a low grunt and grabbed a hold of Stiles' neck pulling him towards the stairs, "Ow! That hurts; I'm in pain here Mr. Sour Wolf!" Stiles whisper yelled as he pulled on Derek's hand to try and get it off, he failed to do so but eventually Derek loosened his grip and let go of his neck.
Stiles rubbed his neck, "I probably have whip lash or something, thanks a lot! You are such a nice person. Nicest person I've ever met!" He continued to whisper shout even though they were upstairs.
"Aren't you just full of sarcasm tonight?" Derek asked, and Stiles was almost sure he saw Derek smile for a few seconds before his lips went back into a straight line.
"I'm an expert at Sarcasm." He informed the other man, he was proud of his sarcasm because it was something he was great at.
"You're also an expert at being annoying." Derek added and turned his back on Stiles as he walked towards Stiles' bedroom.
Stiles just stared at Derek's back, his mouth hanging open because he didn't have the chance to reply to Derek's rude statement. He eventually followed Derek into his room before asking the first thing that came to mind because he had no filter, "How did you even know which room was mine?"
"It smelt like you." Derek shrugged his shoulders like it was the most obvious thing ever.
Stiles tilted his head to the side, "You know my smell? What do I smell like? Do I smell like awesomeness?" He couldn't help himself, he just loved learning more about werewolves and learning what he smelt like seemed very important at the time.
Derek sat down in Stiles' computer chair, clearly just making himself right at home. He looked up at Stiles, both eyebrows raised, "You just smell like Stiles." He answered, and well, that was a disappointing answer.
Stiles needed more details, "Care to elaborate? You shouldn't let your werewolf senses go to waste when you could tell Stiles what he smells like."
Derek let out an annoyed sigh, "You just smell like Stiles, there's no better way to explain it. But I can also smell emotions. Like sadness, happiness, anger."
Stiles nodded along as Derek gave him another lesson on werewolves, "Then what are my emotions right now?" He asked, because he was born without a filter.
Derek didn't say anything at first; he just stood up from the chair and walked towards Stiles. Derek invaded his personal space, as he always did, and sniffed him.
Stiles' eyes widened, "Did you just- did you just sniff me?"
Derek took a step back and answered his earlier question instead of the one he just asked, "Anxious. Lust, but that's probably just your teenage hormones." He paused after that and Stiles almost laughed because that counted as a joke. Derek Hale told a joke.
"You're lonely." Derek added, as if that wasn't obvious to everyone even if they weren't a werewolf with super smell.
Stiles nodded his head, "I don't exactly get attention from…anyone." Stiles explained even though he didn't think it needed an explanation.
Derek snorted loudly but didn't say anything; he just sat back down in the computer chair. Stiles stared at him, not knowing what to do or say.
"You can go to sleep." Derek told him, he probably smelt the anxiety rolling off of Stiles when he didn't know what to do.
Stiles nodded but then shook his head, "I can't sleep, not knowing that they could come here any second. And you may think you can handle them but you don't have your pack with you and they do. They might over power you. My dad could get hurt. You could get hurt."
Derek just stared at him like he was a puzzle that was impossible to solve, then asked the most random question, "Didn't you say you had to take your meds?"
Stiles just stared at him but then he remembered, he still hadn't taken his meds that day. "Yeah." He whispered and grabbed the pill bottles off of his dresser.
After he took his pills he sat down on the edge of his bed, his eyes landed on Derek who was sending a message on his phone. It was weird seeing Derek doing mundane things. Like texting.
"Who are you texting?" Stiles asked, staring at the phone in Derek's hands.
"Scott, I told him I'm protecting the human." Derek answered then glanced up from his phone, smirking at Stiles.
Stiles let out a chuckle then laid down on his bed, pulling the blankets over top of him as he whispered, "You're so stupid Derek. The human can protect himself."
Stiles was staring at the wall but he could imagine Derek rolling his eyes, "Just go to sleep, Stiles." Was Derek's reply.
Stiles smiled against his pillow, "Yeah, that's the plan. The human sleeps while the creepy werewolf stares at him to make sure nothing tries to eat him."
