No one notices that Nathan doesn't come to supper sometimes. No one notices that he has developed the habit of climbing in and out of his window late at night. No one notices. It's not because they're a horrible pack or because they don't love him. They're an amazing pack, and everyone loves him with all their hearts. It's just that he's always been quiet and off to himself (just like his dad), so the changes aren't really changes at all.

With Deaton, he has someone to talk to; someone that understands that humans can be powerful, too. He's been training with him for three years now, ever since Deaton saved him in the woods that night. Nathan has learned a lot of things. He knows all the ways you can use mountain ash. He has all the types of wolfsbane memorized. Sage can do this, and mistletoe can do that… He's read about werewolf legends from all over the world.

Like most nights, he is making his way to the vet's office. He stops when he hears a roar. He tries to listen, but he can't hear much. In the streetlight, he can see a large figure running out of Deaton's office. Once it's gone, Nathan runs into the office. There is blood everywhere, and Deaton is lying on the office floor.

"Alan!" Nathan runs to him.

"Shh… I'm fine. I'm fine. Go, Nate. You have to warn your father. The rogue's back. He wants the Hale territory." Deaton nods his head toward the door, and Nathan finally stands. He slowly back steps to the door. "Go!" he shouts, and Nathan runs.

When Nathan storms into the Hale house, everyone looks up and stares at him. He is panting and covered in dirt and blood. Stiles is the first one to run to him.

"What happened?!" He checks over him to see where the blood is coming from.

"There's…" he gasps in air. "There's an alpha. He's going to try to kill Dad."

"What did he do to you?"

"Nothing. Dad, I'm fine." It's harder to tell who the kids are talking about now that they think they're too old to say 'daddy', but Stiles doesn't think it's the time or place to mention that for the hundredth time. "We have to warn Dad. It's coming. It already attacked Deaton."

"Deaton?" Scott asks. "How did you find that out?"

"I was there. There was so much blood."

"Let's kill this thing," Laura states as she stands up.

"No. We can't just run out and attack it. It's too strong. It was strong enough by itself when it attacked me three years ago. It has a pack now. I saw their footprints at Deaton's. We need a plan."

"You've seen it before? It tried to attack you?" Stiles is even more panicked now. "When? When did it attack you?!"

"Three years ago. I was out on a full moon even after you told me not to, but that doesn't matter now. Dad's in danger."

The pack's attention turns to Derek as he charges into the house.

"Are you okay?" he asks as he pulls Nathan into a hug.

"Dad, there's an alpha. He has someone with him…"

"There're only three of them. It will be okay. We can take them." He looks at the pack. "Scott, Boyd, Isaac, let's go."

"No! Dad! Force won't stop them. I've seen it. It's… It's not like you guys. There's something different. It's crazy. It's a freaking human sized wolf. You…"

"We'll be fine. We've taken down crazed alphas before."

"No, Dad, please."

Derek kisses him on the forehead. "All of you stay here."

An hour later, the men come back bloodied and beaten. They're all alive and healing, but they've been hurt. Stiles runs to Derek and hugs him tight.

"Are you okay?" Stiles kisses the bruises on his face and refuses to let go.

"Nathan's right. It's big. Bigger than Peter ever was."

Scott lets go from hugging Allison and Kierstan. "We got away, but they're coming back. They'll be able to pick up our scent. We have to think fast."

No one sees Nathan run out of the room.

Derek and the betas form a plan and are ready to leave when the air begins to crackle. Derek looks and sees his son finishing off a mountain ash barrier around the house.

"What are you doing?!" Derek shouts.

Nathan steps into the house. "You're going to get yourself killed. That thing's too powerful." He goes to the closet and pulls out a small box. "Now it can't get in, and you can't get out." He starts to cross back outside.

Derek grabs his arm. "You're a child, Nathan. You don't know how to take down an alpha."

"Dad did it with a lot less training than me." He looks over at Stiles. "I can do this."

He pulls away from his father's grasp and runs out into the night.

"Nathan!"

The pack spends the next twenty minutes searching for a way out of the house. They finally find one through the basement's hidden entrance. Nathan covered that entrance too but there was just enough room to get a stick and swipe some of the ash away. They run through the woods in the direction of the sound of the fight.

Stiles gasps when he sees his son fly through the air. Nathan lands wrong on his leg, but it doesn't break. The beast is on top of him before anyone can get to him to help. It's a horrible situation that is getting worse with every minute, but in the blink of an eye Nathan has swung his arm around and stabbed the alpha with a small knife that is covered in wolfsbane.

The monster recoils and staggers back. Nathan forces himself up on his hurt leg and lunges for the alpha. He grabs onto the knife's handle and forces it deeper. With all his might he twists the knife until the blade breaks off. The wound begins to smoke, and the wolf howls. The two betas under the alpha's control charge forward, but stop when an arrow whirls through the air. The alpha collapses; dead from Laura's expert shot. Good thing Allison didn't listen when Derek said not to teach anyone else how to shoot the crossbow.

Derek, his daughter, and Boyd charge off to take down the two betas that have turned and fled. Everyone else rushes to Nathan who is still lying by the hulk of the huge alpha wolf. He jerks away before any of them can touch him.

"Are you okay?" Stiles looks over his son's injuries. He has a few scratches and bruises, and his leg is tender, but he isn't severely injured.

"I'm fine, Dad." He stands up and limps away from Stiles. "Hold on." The young boy takes off his leather jacket and throws it on the ground. He reaches into his pockets and pulls out a variety of blue and purple flowers and piles them onto the jacket. He pulls off an amulet from around his neck and proceeds to wipe off the mountain ash symbols that were painted onto his arms. He shrugs. "Told you I could help."

Stiles steps forward and holds him tight. "Don't you EVER do something that stupidly brave again. Do you hear me?"

"Yes, sir."

Logan runs to his twin and smacks him on the head. "You scared the crap out of me… but that was awesome!"
