Right now this very moment we are all in danger. Because of me you will never be safe again. From now on remember. A there is no such thing as a safe place, some places are just safer. And B if you choose to come with me now I can not ensure you will make it out alive.

Sherlock's p.o.v

Bored! My potions class was dismissed early and I'm waiting for John to meet me in our usual spot. I wait by a huge oak right on the fringe of the forbidden forest. Forbidden. Not really. We've gone picnicking in there like ten times. I waited for a few more minutes before I saw Molly running towards me.
"Professor Snape wants to see us!"
"Let's go!" We jogged towards the school. Molly lead me into the defense against the dark arts classroom. I expected to see a lot of  students gathered but it was just Sebastian, Jim, and John. They sat in the first few seats. I went to sit between John and Molly. Snape was sitting at the big desk in the front. He finished scribbling notes on a piece of parchment with a big black quill. After three weeks of Hogwarts I had been in detention with Snape five times but never with other people. What did John and Molly do to get detention anyway? They were the teacher's pets.
"I suspect you are all wondering why I summoned you." We all nod except me. I mutter "obviously" under my breath. Snape turns to give me the 'death glare' that I have grown immune to. He clears his throat and continues.
"Something is coming. Something bigger than all of us. I need help destroying it and even though you're all just first years, Professor Dumbledore feels that you you're all a good choice. What do you say?" I looked around at everyone. Molly's eyes were filled with fear, Jim's were filled with bloodlust, Sebastian's were filled with concern for Jim, and John's were filled with determination. I felt the same feeling of worry that Sebastian must be feeling. Not my John. I stopped myself right there. He's not my John. He's just John. Not mine.
"We'll do it." Jim met Snape's firm stare. Snape cleared his throat again.
"Right now this very moment we are all in danger. Because of me you will never be safe again. From now on remember. A there is no such thing as a safe place, some places are just safer. And B if you choose to come with me now I can not ensure you will make it out alive."
"What do you mean 'because of you'?" Molly piped up.
"I've brought this fate upon us. Don't tell anyone. From now on you will not go to class. We will meet in the courtyard every day and I will train you. Now go enjoy your evening because it very well might be your last." We walked out of the class room.
"I promised Jasmine I'd help her study." Molly walked back the Hufflepuff common room. I looked over at Jim and Sebastian who kept giving each other loving looks. I poked John and pointed at them. He nodded.
"We have to go finish up some homework we'll catch up with your later." John led me away by my arm. I took one last glance back at them. Jim mouthed "thank you" before being pinned against the wall by Sebastian who immediately started snogging him. I don't blame him. Snape did say that this evening might be our last. If I loved someone and there was a risk of losing them I would hold them tighter than ever before. Maybe that's why I was gripping onto John for dear life. What was I thinking? Did I love John? I was too busy thinking to pay attention to where we were going so I was a bit surprised when we showed up at the cliff edge in the forbidden forest. John and I stood there holding pillows and sleeping bags in our arms.
"Professor Dumbledore gave us special permission to camp out here tonight." I turned towards John as he spoke. He was setting up his sleeping bag. I decided to do the same. After our makeshift beds were set up John sat on the edge of the cliff and motioned for me to do the same. We sat in comfortable silence for a little while, watching the sunset.
"Sherlock?"
"Yes?"
"Do you think we'll be okay?"
"No."
"Wow you're an optimist."
"John, we have to be prepared for the worst. There is a very good chance we might not survive."
"Then there's something I need to do."
"What is it?"
"This might be my last chance so I'm just going to do it." John stood up. Confused, I stood up too. I didn't know where he was going with this until he started to lean in closer. He lightly pressed his lips against mine. I stiffened. My body froze in place, and I was unable to enjoy the moment. I liked no loved John but I wouldn't be good enough for him I would just break his heart. I'm a high functioning sociopath! I would just hurt him. He deserves better. Wait. Since when do I care what other people think about me. No! I can do this! I will be strong for John. I am about to kiss him back when he breaks the kiss and runs away. I was to little to late. I flew into the woods after him. Searching frantically. I had to find him. What if something happens to him. I searched for an hour before I got an idea. By the time I got back to the cliff it was dark. I quickly found John's scarf and cast a location spell on it. I silently followed the scarf to a little clearing with a river running through it. John sat on a rock crying quietly. I walked as quietly as possible and embraced him from behind.
"I'm sorry John. I know what rejection feels like. Not that this is rejection."
"What? Not rejection? How can you say that?"
"I didn't reject you. I realized a little too late that I love you."
"You love me?"
"If I didn't would I be here?"
"I guess not." He looked back at the stream sadly, but didn't cry.
"John?"
"Yes?"
"What made you decide to kiss me now of all times?" He looked at me with big sad eyes.
"Because I might lose you forever. Or vice versa." I was overwhelmed with the truth in his words. We could die. One things for sure if he died, I wouldn't out live him for long. It's depressing to calculate your own chance of death. There's a 75% chance of me dying. Only a 50% chance of the thing killing me. The rest is suggesting John dies and I kill myself.
"Sherlock?"
"Mm?"
"What are you thinking about?"
"I was calculating. There's a 50% chance of the thing getting me, so all in all there's a 75% chance of death. Only 50% chance for you though. As well as Molly and Jim. But Sebastian is 75% like me."
"Why?"
"50% for you Molly and Jim because that's the chance of the thing getting you. 75% for Sebastian and I because... Never mind."
"Sherlock."
"75% chance for Sebastian and I because if you or Jim don't survive we'll kill ourselves." I finished the last part quietly.
"Sherlock! Promise me that if something happens to me you'll keep going. Find someone else." I stared at him in disbelief.
"How could I find someone else?"
"I don't know. Lets just not talk about it." He turned around and pulled me closer.
"But for tonight I'm not letting you go." He stared into my eyes and I saw something in them. It wasn't lust, more like affection. He grabbed the collar of my coat and pulled me into a long slow kiss and I swear, I wanted to stay there forever.
