(Derek's P.O.V.)

I woke up in a daze, my ears ringing before the sound of a faint heartbeat reached me. Sitting up I looked over and saw Destiny barely breathing as she smiled at me.
"Des."
I crawled over to her and held her against my chest.
"Don't do this to me Destiny, come on."
"Derek."
Her voice was so weak, it was painful to hear.
"I-I-I couldn't kill her."
I held her tighter.
"Shh don't talk Destiny."
She whimpered and clung onto me.
"It hurts Derek. I didn't think dying would hurt."
I kissed her, pressing my hand onto her cheek and pulled her pain into me, my head immediately exploded in pain, I blinked back the pain before pulling my hand back.
"Please Destiny, don't leave me, this wasn't supposed to happen, I was supposed to marry you."
I paused as tears welled up, I could hear footsteps and judging by the gasp and near silent wail it was Stiles.
"I was supposed to get you pregnant with our pups, our children, we were supposed to grow old together and see our grandchildren."
I started crying, holding my mate to my chest as her breathing started to become shallow.
"Derek?"
I looked down at her.
"I love you, and Stiles, make sure he know that I'm sorry wasn't there for him like I was supposed to be."
She gasped and panted; bending down I captured her lips in mine one more time as her breathing stopped and I heard her heart give two weak beats before stopping. Choking back a sob I looked up to see Stiles in tears as he held her hand, when he had grabbed it I wasn't to sure.

"Derek?"
I looked up at Peter, I knew I looked like hell, my mate was dead, we were waiting until we found her dad to have her funeral, and I also knew I was slowly dying as well.
"How long do I have?"
He sighed and took a seat next to me on my bed.
"Maybe a month. It's hard to tell. But not long."
I nodded, anger gripping my grieving soul as I looked up at him again.
"Help me find her, I'm going to rip her head from her body."
Peter smirked and nodded.
"You want to take out Deucalion as well."
It wasn't a question but a statement and I nodded.
"Then we only have tonight, it's the lunar eclipse, it's the only time we will have the advantage."
"Why are you helping me this time?"
He smirked at me.
"Because I want revenge as well. She was your mate but she was like a daughter to me. Everyone wants their own revenge for her death, she was a one of a kind person and wolf. She shouldn't have died like she did. And we will make that bitch pay for what she did. Now get up, we're losing daylight."
I growled and stood up, locking onto my anger as we came up with a plan.

I sat smug as Scott took a video and sent it to Jennifer.
"You sure this is going to work?"
I nodded.
"Trust me."
The teenager nodded as we waited. A few minutes passed when Deucalion appeared.
"What do you want?"
I growled at him.
"I merely want to help, I have my own reasons for wanting her dead. I didn't think she would kill your mate like that."
I shook my head, already feeling my heartbeat slowing every few minutes.
"I'm going to kill her."
"Now boys."
We looked over and I growled as Jennifer appeared in the doorway.
"There's no need to fight over me."
In an instant I was over taken by my wolf and I let him attack her, I felt him slice through her skin, our teeth ripping chunks of her skin and muscles off her bones. Her screaming was barely noticeable as the lunar eclipse started and I was forced back into control. Stepping back I smirked darkly at the state she was in. Most of her right shoulder was missing; giant slashes covered her chest and stomach. I smirked as I grabbed her by the throat.
"Let them go."
She tried to shove me off and I simply pushed back against her.
"You have 15 minutes before my wolf tears the flesh from your bones, and when he's finished, he might take pity and kill you."
I dropped her and watched her as she decided to do something extremely stupid in her state. She ran over and placed her hand over Deucalion's eyes, giving him his sight back as the man screamed, I could only guess she was hoping he would save her. When she pulled her hand back the fifteen minutes were up and my wolf was back in full force as he took over again and started ripping her apart. I knew I was covered in her blood by the time he stopped. Looking down I smirked when I realized he had killed her. He literally sliced her in half and cut her head off. Making sure she wouldn't be back to bother Scott or his pack again. All of a sudden I felt weak and collapsed on the spot.
"Derek?"
I smiled at Scott as he looked down at me in concern.
"What's wrong?"
I continued to smile as I felt my heartbeat slowing, I knew Scott and Deucalion could hear it as well.
"I'm going to join her Scott."
"What? You can't die on me."
I just sighed.
"It's what happens when a werewolf's mate dies, we have a few months at most before we pass as well. Watch after Stiles and Isaac okay? It's what Destiny wants. And."
I paused taking a breath as it became harder to breath.
"And be a better alpha than I was."
Scott had tears in his eyes while looking lost at what to do.
"You were a great alpha Derek."
I smiled, I knew he was lying, but it was good to hear as I closed my eyes and felt the last bit of breath leave my body as my heart stopped and I was finally able to join my mate and pack.

THE END
