A/N: My first cross-over! And Erica and Boyd are not captured by the alpha in this.

Pairings: SladexDick (Nightwing), DerekxStiles

Mercenaries, Nerds and Werewolves

"I hired you for one reason. I trust that you can do the job."

"Trust me Mr. Argent. When I take on a mission, I never fail." Deathstroke clicked his gun and threw the picture of scott in the air. It was blown by the wind, but Slade, the best mercenary of all time shot it into pieces without one miss.

"Okay, I gotta tell him. But I don't wanna tell him. But you have to because he's your bestfriend and Derek and him are getting along better. And there's that whole alpha thing and you don't want him to figure out at a critical point where he's dying and he'll get shock and die from it."

"What're you talking about?"

Stiles jumped when he heard Scott behind him. He turned around and tried to think of something while babbling nonsense.

"I...was just...trying to remember what my locker number is! And now I remember." He laughed awkwardly. Scott let it go since his friend was always weird.

Scott shrugged. "Okay, but I think Derek's rubbing off on us or stalking us. I can smell his scent a lot. Its even stronger when I'm next to you."

Stiles gulped. "He didn't teach you about how great your senses can be."

"Yeah. He does. He-"

"Hey, coming to training tonight."

Stiles grimaced when Isaac bothered them.

"Yeah, just gotta make sure my mom's safe." Scott answered happily and the two stared at each other with creepy smiles for a bit too long.

"Uh hum." The non-werewolf in the group interrupted their moment. "Now that you know, how about you go somewhere else. For once." Stiles did not like this guy. He was this sick murderous werewolf and now he's getting all cuddly with Scott. These days, he hasn't been able to see Scott in a while.

Isaac glared at the nerd and then looked at Scott. He chuckled. "I'll see you in training, Scott." He smirked and then walked away. Stiles felt relieved and looked back at his friend who was tilting his head staring off in space or someone's ass.

"Dude!"

"Huh? Sorry, what were you saying?" He shook his head and tried to stay focus. Stiles let it go reluctantly because he had more important matters other than his friend getting into the clutches of a psycopath.

"There's something I have to tell you." He paused feeling the half of his heart stretch up as the other stretched down.

"Like?" He pushed on.

"I...am...dating someone." He tried to force the words out but felt like the air was getting trapped in his throat irritably.

"Really? Stiles Stilinski has a girlfriend? I'm proud of you man!" He patted his arm.

"No, it's not like that. Its...its..." Suddenly his heart was starting to stop and sweat was pouring onto his palms.

"Stiles?" His friend looked at him in wonder of what's wrong. The bell rang. "Tell me later, dude. I'll see you." He patted his arm again and walked away. Stile cursed himself.

Afterschool, he went home feeling angry at himself for not telling Scott the truth. He took off his shirt before entering his room to find Derek Hale, who immediately slams the door and throws the nerd on the bed.

They got into a passionate kiss with Derek removing the teen's pants.

"Derek, we need to talk. Not that I don't like this. I like this a lot. It's just that I-" He gasped when something wet and hot interrupted his thought. "Aaaah~Never mind."

It was always like this. The werewolf knew how to shut up Stiles everytime. The only thing you could hear were screams, yelps, moans and squeaks out of the kid for the longest time without hearing one word. He never had to scream for more because Derek always gave him too much to handle that his whole mind turns foggy.

Afterwards, Stiles was a complete sweaty mess on his bed with claw marks dug into his matress. He was lying on his stomach catching his breath and feeling the hot air go to his head making him sleepy.

"What did you want to talk about?" Derek asked as he was getting dressed.

Stiles was wondering what he was talking about until Scott popped in his head. He groaned and dug his head into his pillow. "It's Scott. We have to tell him."

"Doesn't he smell my scent when he's near you?"

"He thinks you're just rubbing off on me. No pun intended." He lies on his side placing his smirking cheek on his hand.

"Maybe I haven't done it enough to get him a clue. I can smell Scott all over Isaac and I even told him about it."

Stile's eyes grew wide and he sits up abruptly feeling a sharp pain on his bottom. Something he could not get used to. He jumped out of bed, not really helping him but not the most important thing right now. "Scott is sleeping with Isaac!"

"And not very good at hiding it. I caught Scott doing him in the broken subway train. Even Erica and Boyd knows."

"And he never told me!"

"See, everything's fair."

"But Scott doesn't know about us."

Derek growled as he began to feel irritated. "Scott doesn't need to know who you're sleeping with." He kissed his boyfriend wasting no time in making him breathless and jelly.

"Uhm, y-yea-YEAH! But I'm sleeping with his alpha leader! Isn't this awkward for you?! You're sleeping with his best friend!"

"Now Isaac is his best friend." He smirked.

"Never joke with me about that!" He pointed angrily at his boyfriend. HE is Scott's bestfriend. He was his bestfriend while he was going out with Allison and he's still going to be even though he's sleeping with Isaac!

"So Scott means more to you than me?" Derek growled in anger as he gripped his boyfriend's butt.

"Hey, I've known him since Kindergarten, and I've known the nice side of you for as long as we have been having sex but before that, actually even now, you've been constantly threatening to kill me if I didn't do what you said."

"Only because you're into it."

"I am not."

"Shut up or else I will rip your throat out...with my teeth." He snarled as he was in semi-wolf form with his hand wrapped around Stile's throat. He had that hand slide down with his sharp fingers tickling the skin that the boy shivered in fear and pleasure. The hand grabbed his prize.

"Okay fine! You're right! But Scott deserves to know and maybe he's not completely serious with Isaac. Maybe that's why he hasn't told me."

"Or the fact that you would've freaked out just like right now." He began stroking the prize but his hand got swatted away.

"We don't have time for that!"

"RAWR!" He tackled his lover down.

"I said we do-OH!"

Abandoned Subway station

"You're late." Boyd said when Derek finally arrived.

"I had problems to settle."

Erica snorted and Isaac smirked. Boyd shook his head as he pity the fool. Scott was lost but didn't bother asking.

Derek looked at his pack and pointed at Boyd, "Work on your predictability." He pointed at Erica, "Work on your technique." He pointed to Isaac, "Work on not being stupid." He pointed at Scott. "And you...work on your common sense."

The pack laughed at the confused werewolf.

"Stop laughing!" Derrick snarled. "This is serious! The alphas are coming for us! We have to get ready for anything. And I mean anything."

Stiles house

Sheriff Stilinski walks into his home after a tough day. The cases are becoming easier to solve but not easy to close. He stretched his worn muscles and walked up the stairs to find his son. He opened the door and felt his heart drop.

There was no sign of of his son but a deep gash in the bed that looks identical to the animal attacks.

"Stiles! Stiles!" He ran frantically around the house until he stops at the stairs to see a worried Stiles below.

"Dad, what happened?" He asked worriedly.

The father walked down and hugged his son to make sure it was him. He still felt fear when his son went missing after the lacrosse game.

"Dad, I'm okay. What happened?" He asked seriously.

"Nothing. I thought you were taken again when I saw the claw marks on your bed."

Stiles mentally cursed himself when he forgotten about them. He was busy throwing the bed sheets after washing them because he didn't want there to be questions when the possibility of it being found for some unexplainable reason will happen.

"Oh, that was an accident. You know how its almost halloween and Scott's claws accidentally stuck to the bed." He lied. His father gave him a suspicious look but he didn't see the werewolf incident at that time.

"So do you need a new bed."

"No, I can live with it. I'll just remind Scott not to dig his claws into my bed again. Okay, good night!" He ran upstairs and got into his bedroom. He quickly covered his bed and was about to get on until he heard a click of a gun.

"Do what I say and you'll live."
