A/N
Hey guys! A little note: this is a prequel to my Supernatural and Teen Wolf crossover "Blood on my Name." I highly recommend reading that one first. If you don't want to, the nutshell is that Stiles is the Winchesters' half brother in a totally explained way. I'll be updating this daily and it will be at least 10 chapters. FYI, the chapters get longer. Probably longer than they should be. Thanks so much for reading, please review, and enjoy!
Ch. 1
Summer Break. Kinda.
"Stiles!" Sheriff Stilinski shouted up the stairs to his son. "Get down here!" There was a crash, and Stiles came rushing down the stairs, with his hair disheveled, his shirt half buttoned, his belt undone, and what looked like shampoo on his face.
"Dad! What's up? What's wrong?" Stiles asked, blindly reaching for his baseball bat, but missing and falling over. He went down with a squeak of protest, then bounded back up immediately, Arms out in front of him and eyes rapidly looking back and forth, searching for a threat.
The sheriff stood in front of him with his arms crossed. "You haven't taken your medication, have you son." John Stilinski asked.
"Nope." Stiles said matter-of-factly. It was then that he noticed two hulking figures standing in the doorway. One had long brown hair, the other had short hair. Both were wearing flannel shirts with green overcoats, and both had ridiculously amused expressions.
"Sam. Dean. Good to see you." Stiles said nonchalantly as he tried to straighten his hair, fix his shirt, buckle his belt, and wipe the suds off his face, all at the same time. Needless to say, he failed, so he just stood still and took in the ridicule.
"Stiles! Nice to see you!" Dean said brightly, a teasing expression on his face. Stiles flushed.
"Yeah. What are you guys doing here? Last time I called you were on the other side of the country." Stiles asked, shamelessly beginning to pull himself together.
"Virginia. We were investigating a hunt. Do you remember what it was about?" Sam asked, stepping inside and taking off his coat. Dean followed suit.
"Vampires. Yeah, I remember. Did you guys take care of it?"
"No. See," Dean looked at the sheriff for help.
"Stiles," the sheriff addressed his son after clearing his throat. "The boys... well, they need your help."
"My help?" Stiles asked, astounded. "Why? You've never taken me on hunts this serious. How could you possibly need my help for a nest of vampires?"
"We'll explain in the car." Dean said firmly.
"We're leaving now?" Stiles all-but-shrieked. "I just got up five seconds ago! Now I'm going across the country to kill vampires?" Stiles turned to his dad. "How can you possibly be okay with this?"
"Well," the sheriff grumbled, "I thought you'd be ecstatic."
There was a pause, and then a wide smile broke out on Stiles' face. "Oh, I am." he said reassuringly. "I just had to make sure I wasn't dreaming."
Stiles marched up to his half-brothers. "Give me five minutes." Sam and Dean nodded.
"Oh." Stiles said to his family when he was halfway up the stairs."What's my cover story?"
Dean rolled his eyes. "You know you're going to have to tell your werewolf buddies who you are eventually."
Stiles shot him a bitchface. "Not today."
"John's covering for you." Sam interrupted. "He's going to tell all your friends that you have mono." Stiles nodded and trooped up the stairs. He was well on his way to packing before he realized it.
"THE KISSING DISEASE?"
Sam and Dean grinned.
"So this case?" Stiles snapped, reclining in the back seat of Dean's shiny black '67 Impala. He was still a little ticked at his brothers for such a lame cover story, but nevertheless he was excited for the hunt. Vampires! The most Sam and Dean had dragged him to had been local hauntings, and even those had usually been busts. He knew how to kill Vampires, but had never met one before.
"Right." Sam said, turning around in the passenger seat to face his brother, while Dean kept his eyes on the road. "So get this. This town we were in, Mystic Falls, has had whole strings of animal attacks. Enough to make Mystic Falls look like the safest town in the world."
"Probably pre-Kanima." Stiles muttered.
"Right." Sam said. "Good job on that, by the way. It's too bad your friends couldn't trust your instincts."
"I knew it was Matt."
Dean groaned. "We know, Stiles. How is the lizard freak anyway? Jason?"
"It's Jackson. And he's fine. He's moving to London in a couple days, good riddance. Derek's a little shaken up, what with three of his betas gone or about to be gone. Lydia's a little mad about the whole thing, and with Allison in France for the summer she's been talking to me. Scott's being a lovesick puppy, but what else is new."
"And the sheriff?" asked Dean.
"He still can't believe a 16 year old boy controlling a lizard told him what to do." Stiles said with a laugh. Then, more seriously, "He's fine. He lost a lot of officers, but I think he'll be okay. What's up with these vampires?"
"Well," said Sam excitedly, "there have been at least 20 reports of animal deaths in the last month alone. So I did some digging, and the reports go back further. Tons of them." His voice dropped to a whisper. "All the way back to the town's founding in 1864. Whatever's going on here, it's been going on for a while."
"What makes you think it's vampires?" Stiles asked. "It could be a Wendigo."
"Nah." Dean said over his shoulder. "Too far south. And the descriptions of the victims. Whatever lies were in the papers, one thing rang true. The victims were all exsanguinated."
"Did you talk to the cops?"
"Yeah. Went full on fed." Dean replied.
"Nothing?" Stiles asked with disbelief.
"Yeah. Either the Sheriff didn't buy it, or for whatever reason she's protecting the vamps. Which got us thinking."
"Turns out the town is kind of cliquish." Sam interjected. "They're big on old traditions. Here's the clincher. In Dad's journal, he mentions hearing about a vampire hunting society in Virginia. It never said where, but if it were anywhere, it'd be Mystic Falls.
"The Sheriff isn't protecting the vampires, she's protecting the society." Stiles finished.
"Bingo."
"What does this have to do with me?" Stiles asked. Sam and Dean looked at eachother shiftily.
"Thing is, Stiles," Dean said. "This hunt, something's not right. A lot of attacks are connected with the school. We need to get all angles, so you need to go undercover."
A laugh escapes Stiles' lips. "I'm a little young to be a fed, Dean. Remember what happened last time?"
Sam covered his hand with his mouth to hold back a chuckle. Dean glared at him.
"I remember. That's why this is different. You're going to Mystic Falls High School."
Stiles stared at his brother in disbelief. "Don't worry." Dean continued with a wave of his hand. "You'll be back in Beacon Hills in time for your Junior year."
"School starts in a month, Dean. We're starting late because of all the trauma."
"Well MFHS starts in three days."
"A MONTH?" Stiles whined. "I have to go to school for an extra MONTH?"
"Yep!" Dean said with a smile. Suddenly, a pinging noise filled the car.
"It's Scott." Stiles said, looking down at his phone. "He wants to know how I'm doing."
"Why?" Sam asked. Stiles rolled his eyes in disbelief.
"I have mono, remember?" Stiles shot Sam a nasty look. Sam grinned in response.
"Alright you two, cut it out." Dean said. He looked at his speedometer. "We're about to hit the California border. At this rate, we should get to Mystic Falls just in time for school to start." Stiles glared at Dean. "Sit back, kid." Dean said, ignoring his brother. "It'll be a long drive."
"Killing the vampires better be worth it." Stiles muttered.
