Stiles could feel it rising. Power prickled over his skin from 4pm onwards. Derek had let Stiles go to his morning classes and then took the entire pack to the location Stiles had found, around lunch.

"The moon starts to rise around 5:30." Derek explained. "You will feel it about an hour before hand. The moon is a strong force but not until it is at the highest point in the sky will you feel its full effects. It will be just about midnight when it will affect you the most but we can't take any chances. I want you chained up at 8, until then I will be keeping a close eye on you. This much power in the air, it's a time bomb waiting to happen." Derek said pacing back and forth in front of his pack, who sat on old wheelie chairs that were lying around.

"You're tense." Stiles noted.

"Oh really? What gave that away?" Derek asked rhetorically.

"More than usual Captain Sarcasm," Stiles said with a soft smile.

"I just have a really bad feeling about this moon." Derek said looking away.

Stiles wondered if Derek could feel where the moon was and was staring at it or just looking dramatically into the distance.

Stiles chuckled to himself and Derek turned sharply, locking eyes. "Care to share the joke?"

"I was wondering how we were going to pass the time. Then my thoughts turned dirty. I could share if you really want me to." Stiles said winking.

"NO!"

"Please Don't,"

"Stop now!"

The pack spoke over each other and Stiles laughed more. Derek grinned and then frowned. "Stiles come with me." Derek said walking a little away.

Stiles contemplated scooting over on the chair but decided against it, walking like a boring adult instead.

"What's up?" Stiles asked when they were out of sight of the pack.

"Try not to get excited. It will increase your heart rate and make it more likely you will turn under the full moons power." Derek warned.

"Can we try get out some of my excitement while it's still safe?" Stiles asked putting his hands around Derek's waist. Stiles had learnt that Derek likes to be touched and held, despite the constant 'go away' scowl on his face.

"It's too late. I bet your skin is already itching with the power." Derek said running his hand along Stiles' arm.

"Can I lie and say it isn't?" Stiles asked looking up at Derek with a pout.

"This is serious Stiles."
"You are going to give me blue balls." Stiles warned.

"Blue balls are better than wolfing out and attacking someone." Derek said.

"Are you sure? Blue balls could make me 'teenage boy' out and attack you naked." Stiles said.

Derek laughed at the younger boy and they kissed softly. "We have to go back." Derek said against his lips.

"In a minute." Stiles said kissing him again. Stiles enjoyed the stubble pricking his face. It was taking his mind off the moon power prickling over his body.

Derek finally pulled away, leading a frowning Stiles back to the pack, who were pretending they didn't just hear all of that.

Stiles became more jumpy and agitated as the hours rolled on. He went to the toilet just before 8 and when he got back he noticed Becca looked as frantic as he felt. He hugged her and her heart rate calmed a little but that only lasted a second. Both Stiles and Becca were back to being jumpy and nervous within minutes.

Derek wrapped separate chains around the younger wolves and then one around both, locking them together. They sat back to back on the two comfiest chairs they could find. Derek kissed Stiles softly and sat in a chair so they were face to face. Scott sat on the opposite side facing Becca and Isaac sat to the side, mostly on his phone. Texting Allison, Stiles guessed.

Stiles was fidgety. More so than usual. He had almost picked all the stuffing out of his chair handle and his knee was bouncing up and down like crazy. He tried to calm himself but his mind just kept worrying.

Derek put his hand on Stiles' knee. Stiles looked at him with strained eyes. Derek kissed his forehead and Stiles took a couple more deep breaths.

"What are you worrying about?" Derek asked once he had sat back in his chair.

"I don't know. Nothing. Everything. My mind is racing and I can't control it. It's like my ADD and anxiety had a baby and its running rampant in my head." Stiles tried to explain. By the sceptical look on Derek's face it was clear he didn't understand. "Have you never seen a wolf with mental health issues?" Stiles asked.

"Usually the bite clears up any ongoing issues that their human self would have." Derek said placing his hands on Stiles'.

"I was better for a while. I remember being more focused yesterday, but it looks like all that is out the window. Anything can happen with a full moon right?" Stiles joked. No one laughed.

It was quiet for a while, except the slight squeak of Stiles' chair as his knee bounced, until Isaac's phone rang.

"Hello?" Isaac answered.

"I need you back at the room." A voice answered. It was a little distorted but Stiles could hear it as loud as Isaacs.

"What happened?" Isaac said standing up.

"Someone broke in and stole some stuff. The door was broken when I arrived and there's this weird circle carved into it. I'm calling the police but I need you to see what things are missing." Isaacs's roommate said.

Isaac and Derek exchanged looks. "Okay I will be right over." Isaac said hanging up the phone. "What do you think?" Isaac asked Derek.

"I hope this is what my bad feeling was about. I have to come and see it for myself. If there is any lingering scent I may be able to recognise it." Derek said. His hands squeezed Stiles'. "You will be okay. Just keep thinking about your father. I will be back as soon as I can." Derek said kissing Stiles. It was deeper than their normal kisses and Stiles heard Isaac cough a couple of times out of embarrassment. Derek pulled away slowly and Stiles tried to smile to reassure him. "Scott, watch over them. Keep them calm. We still have a little while until the moons peak and I should be back in time." Derek said.

"I'll try." Scott said nervously.

Derek took one last glance at his new wolf before he walked out with Isaac in tow.

Once Derek's car had left the parking lot, Stiles' anxiety spiked. He could feel an attack coming on despite all his efforts to calm down. 'Think about dad. He needs you, if you wolf out and kill someone he will have to hunt you. Dad can't know you are a werewolf; his heart wouldn't be able to take it. You have to calm down, learn how to control it, you can't wolf out for dad's sake.' Stiles internal monologue rambled. Just like everything else that night, the full moon won and Stiles couldn't think of anything else to keep himself calm.

"Scott I'm going to have an attack and probably change." Stiles warned a little while later. His mind couldn't focus for long enough to be calmed down.

"Fuck. Okay. You need to calm down. Do what Derek said, think about your dad." Scott stammered.

"Don't you think I tried that?" Stiles said almost panting.

"What do I do?" Scott asked.

"Unchain me from Becca and move me away. If I lose it I don't want to hurt her." Stiles said. He was scared of what he might do. He didn't want to hurt anyone but he didn't know how in control he would be once he changed.

"I'm not unchaining you." Scott said defiant.

"Scott please." Becca pleaded. "I'm barely holding on. If he hurts me even by accident I won't be able to hold back."
Scott looked into Becca's eyes. She was sweating and nervous and throwing glances over her shoulder at Stiles.

Scott ripped open the chain connecting the two wolves and was in the process of wheeling Becca away when Becca's eyes went wide. Scott could hear the sound of twisting metal and snapping plastic. He turned and saw Stiles wolfed out. His yellow eyes were glinting, he seemed to have grown half a foot, there was hair covering his jutted out jaw and, Scott didn't think it was possible, Stiles looked dangerous.

Scott was still reeling at the sight when Stiles jumped him, hitting him in the face so hard he broke Scott's jaw and sent him tumbling to the ground. Stiles turned to Becca and growled, in a deep un-stiles like voice, "Don't follow me," before jumping out the window.

20 minutes was all it took before Derek's phone was ringing. He pressed answer and put it on speaker. "What?" He asked.

"Stiles escaped." Scott said with a pant.

Derek slammed on the breaks. "Isaac, keep going. You have to sort out your room and keep an eye out if Stiles arrives on campus." Derek said getting out of the car. He closed his phone and took off running. He wolfed out and was back in the office building in 10 minutes. Derek looked around and took in all the information he could. Becca was still in her chair with one chain around her, Scott was pacing next to her, Stiles' chair was in pieces on the ground and his chain was broken. "What happened?" Derek growled. He was still half wolf and was itching to follow Stiles scent.

Scott briefly recapped what had happened and Derek nodded along. "Stay with Becca. Ring me if Stiles comes back." Derek said before jumping out the window, following Stiles' scent.

Derek was on the hunt now. Stiles had 30 minutes on him and Derek dreaded to think of what he might do.

Derek was half way back to the campus when his phone rang. "I smelt him. He must have gone past my building. Do you want me to chase him?" Isaac asked.

"No. Leave it to me. I will be there soon." Derek said. He hung up and ran faster. Stiles had sniffed around a couple of parties once he got on campus. The scent was getting stronger and then Derek smelled blood and three more scents. Derek turned into the car park and heard Stiles crying. Derek found the source of the blood, one of the bodies was the guy stiles had knocked unconscious. Derek guessed the other body was the other guy that had beat Stiles up. There was also a girl laying a bit away, stinking of drugs. Stiles looked up at the older wolf; the tears down his wolf face were breaking Derek's heart.

"We have to go." Derek said.

"We have to help her." Stiles told him with a growl.

"They are dead Stiles. They can't hurt her. Better to call the police and let them help her." Derek told him. Stiles eyes flashed blue and Derek winced.

"I'm sorry." Stiles said.

"We have to go." Derek repeated.

Stiles shifted back to human when Derek grabbed his arms and pulled him up. He was still crying when they got to their dorm room showers. Derek stripped Stiles and held him under the stream of water, washing off all the blood.

"You are getting soaked." Stiles commented.

"You need to wash the blood off." Derek said ignoring the water.

When Stiles was clean Derek sat him down and walked out with his bloody clothes. Stiles was crying again when Derek returned with a towel. Derek dried him off before carrying him to their room. Stiles kept repeating, "I'm sorry. I'm so sorry," as Derek laid him down on his bed.

Derek stripped off his wet clothes, pulling on a pair of track pants before getting into the bed with Stiles.

Derek held him through the night, through the strongest pull of the moon, through Scott's text that Becca had controlled herself perfectly even through Isaac coming in to check on them. Derek never wanted to let Stiles go again and even though Stiles was still mumbling, "I'm sorry." Derek was the one who blamed himself. He should have never left two new wolves alone to control themselves. He should have never left Stiles.

His last thought before he fell asleep with stiles on his chest was, "I hope Stiles can forgive me."
