He took me to this French restaurant in the neighbor town and paid for everything- Isaac was telling Lydia and Danny about his last date with Argent. It had already passed a months since we signed the treaty with the hunter, the full moon was next week and the weeding this week-end so Argent and Isaac had been going on dates to get to know each other better to not make the transition to hard on any of them. That I allowed it doesn't mean that I liked it at all, especially when my Omega came each day smelling of wolfsbane- We then had a stroll through the park and...

I stopped listening to Isaac because I heard the ringtone of MY Mate and answered it as fast as I could- Stiles!- I greeted with a huge smile, which vanished when I heard her ragged breath- Luna are you ok?!

-I'm so sorry Derek!- she cried- I swear I didn't plan it... I didn't want this to happen!

-Stiles where are you?!- I asked her starting to panic, "Was she hurt? Was it that creature? Why was she alone?".

-At the gym of school- she managed to whisper between sobs.

-Stay there!- I ordered her- That I am on my way- with that said I ended the call, grabbed my keys and rushed out of the house got into my Camaro and drove towards the school. I could hear Lydia calling her mate and Isaac his parents as they got into the car and Danny tried to follow my speed. As soon as I reached the school I didn't even bother to turn off the machine I just ran to where the smell of MY Mate was. I almost tripped when I managed to scent blood coming from where she was, "I'll kill whoever hurt her!"- Stiles!- I shouted when I entered the gym.

-Derek!- she jumped on me and hugged me as if her life depended on it- I am so sorry!- the smell of blood was stronger. I pushed her away and looked for any wounds but found none, then I noticed that the blood wasn't from her. "From who then?"- He came after me, telling me that everything was my fault... that the reason his plans to turn Scotty into a True Alpha failed was because of me- the tears didn't stop falling from her eyes as she continued ranting- He said that if I died you would go crazy, our pack would be destroyed and then his plans could continue- I growled angrily at the idea of MY Mate being threatened, and blamed myself from not being there for her- He attacked me! I only defended myself I swear... I didn't kill him because I wanted to.

My blood ran cold at her words, "MY Mate had to kill someone... I am such a pathetic Alpha that I can't even protect MY Luna"- Who?- I asked taking her back into my arms, "Please let it be someone who won't be missed, I don't want to have problems with Argent so close to the weeding day".

-Deaton- she murmured against my chest and let myself relax, "Good, from what I heard from Argent he doesn't like the guy either"- Scotty will surely hate me now.

-Everything will be fine Luna- I assured her- Mc Call doesn't need to know anything about it, we will bury the body and then forget this ever happened.

-I don't think burying the body will be necessary- Lydia's voice resonated through the gym.

-What?- I asked my emissary who only pointed to the middle of the room- Damn!- I cursed. There was a tree dripping in blood in the center of the gym, the form of the plant was like it was trying to strangle someone. I looked at MY Mate in surprise, until now she had only been able to use fire from the four elements. It looks like now she had achieved the element of earth as well.

-What the hell?!- cursed Jackson as he entered the room, with Boyd and Erica behind him.

Surprisingly Argent was there as well, and he was wearing his usual poker face that broke a second when his eyes landed on his fiancé- I hope you have a good reason for that- the hunter said pointing at the tree.

I had to suppress a growl because we were in already enough troubles with Argent- That is Deaton- began to explain Stiles. Suddenly she was sober, surely because she understood how much importance this had to the pack- He came after me with the intention of killing me, for I had ruined his plans to turn Scott into a True Alpha.

-So you did that in personal defense only?- the hunter questioned MY Luna.

-Yes- she answered- I might have loathed the man... but I am not an assassin.

-I believe you- Argent said after a long pause of just staring at Stiles.

-You do?!- my whole pack and I exclaimed shocked.

-I do- the hunter repeated himself raising an eyebrow in amusement- I might don't trust supernatural creatures completely, but I know when they are lying or not. And no matter how good actress Stiles is, she wouldn't be able to act so traumatized- at his words my attention was back to MY trembling Mate- Take her home, I am sure that the rest of your pack will be able to clean this mess on their own.

Hating to admit it, but Argent was right. MY Mate needed me and my pack could do fine on their own- Jackson I leave you in charge, but hear Lydia and Danny something tells me those two know how to get rid of a body- I carried Stiles bride way towards the door of the gym but stopped in front of the hunter- Argent... thank you for being so understanding of everything.

-No- he shook his head, with a small smile playing on his lips- Thank YOU, of getting rid of those people from me and letting me have a chance with the one I truly loved.

I chuckle at his words before walking away, "Maybe he isn't that bad".

Later on that day after a hot bath and a lot of crying, Stiles finally managed to calm down-It was the first time I killed anything- she admitted to me, as we curled together under the warm sheets of our bed. Her heat had always made me feel safe and loved, but this time it was the other way around. Stiles blamed herself for it, she thought that she was a monster that didn't deserve to be loved.

-It will be the last time Luna- I promised her- I will never let you go through that again.

-Don't make promises you won't be able to keep- she murmured, and I tightened my hold on her.

-Did I ever lied to you?

-Never.

-So, just trust me on this as well- she looked up at me with hopeful eyes full of fear and sadness- I won't let you get hurt like this ever again.

-You better keep that promise Derek.

-I will- "I will do anything to keep it", with that said we both fell asleep in each other's arms.

When there were left twenty minutes before midnight I got off the bed slowly without waking up, dressed and drove towards Erica's flower shop. She had the best bouquets of all the city, and she promised me to open up this late tonight for me-I thought you wouldn't come after all- she said when I arrived. I just scowled at her threateningly but she only laughed.- What kind of flowers would you like?- she asked me once we were inside of her shop.

-White, red and yellow poppy- I answered immediately- With one gladiolus in the middle.

-It looks like you had been thinking of it for a long time- she commented with a mocking tone, if I didn't know her already I would accuse her from not respecting her Alpha- The majority buy roses for their couple's birthday, well you had never been normal. And that is still true if you leave your claws and fangs out of the equation.

-Just make the bouquet Erica- I ordered her, as always she did as I told her- And remember to come at the House in the morning, we need to prepare everything so Stiles will have the best birthday ever... even after everything that happened this afternoon.

-Derek you need to know that we already got rid of the body- my Beta told me with a sad tone- Lydia and Danny came up with a formula to melt the tree with Deaton inside- "Why doesn't it surprise me?"- The rest of us worked on repairing the damage of the gym's floor, that caused the tree when it appeared. No one will ever notice that a murderer happened in there- I nodded my head, she knows me good enough to know that it is my way of thanking her- How... how is the Luna?

Her question didn't surprise me, but her soft tone yes... it remind me of when I first met her on the playground when we were six years old. Some kids were bullying her because of her condition and I saved her, she was so small and fragile that one touch was able to break her into millions of pieces of glass. When she started hanging around Boyd and I she became more confident and stronger, I had never seen her act like this in a long while.

-She, will be- I said honestly knowing that if I lied to make her feel better, this time she would notice- It is the first time that she kills, Stiles still is on shock.

-It will be the last time as well, isn't it?

-Of course!- I said determined- I will never let this happen again.

-Good. It's on the house Derek- she handed me the bouquet with a small smile. I knew that even if I tried to pay her for the flowers, the only thing that I will manage is for her to be angry at me and not reach the House for midnight.

-Thank you Erica!

When I got to the home my happy mood went away when I heard the lies of Stiles- Dad don't worry... I know that you have to work harder lately with that assassin out there... I'll be fine, surely Lydia will make a huge and unnecessary party for me... I love you too daddy.

-You shouldn't lie to your father- I told her once she ended the call- Happy Birthday Luna!- I was so proud when I smelled that her mood got better as soon as she saw the flowers- I hope you like them.

-I love them Derek!- she took the bouquet from my arms and placed it on the night table, before jumping on me and attacking me with kisses that I accepted gladly- And I love you Sourwolf!

-I love you too Stiles- I told her- But right now you need to rest, that tomorrow we are having a big day.

-But the flowers- she pouted- They need to be put in water.

-I'll do that, you go to sleep.

-Derek!

-Sleep.

-Ok- she continued pouting but did as I told her, "For once in her life!". However, when I returned from the living-room after putting the bouquet in a vase she was still awake- I couldn't sleep without you next to me- she said shyly before I could open my mouth. And how could I get angry at her puppy eyes and pouting lips. I got into the bed and hugged her as hard as I could- Thank you Derek... for everything- she said before falling asleep.

-Your welcome- I kissed her forehead and let dreams take me to their land.
