My Daughter? (A Derek Hale daughter/Liam Dunbar fanfic)

Unleashed

At the Animal Clinic, Scott is assisting Dr. Deaton by holding down a dog for an injection while its owner frets over the circumstances.
The dog's name is Bullet. His owner explains that all of his dogs have gun-related names because he is from a military family.
As Scott pets him, Bullet rolls over and presents his belly in a sign of submission. This prompts his owner to say "Looks like he knows who the Alpha is." This alarms Scott and seems to disturb Deaton.
Outside, Bullet's owner attempts unsuccessfully to get the dog into his silver Toyota Corolla. Instead the pup runs off between two warehouses. The owner follows and believes he has found the dog under a dumpster. When he reaches in, he gets bitten and blood wells on his hand. He then sees Bullet is sitting across the way. When he again looks under the dumpster a voice whispers "Closer, come closer."
Scott discovers a single mistletoe berry while sifting through a sample of Bullet's stool. Deaton explains that the plant is poisonous to dogs and humans. Scott hears Bullet barking outside and goes to investigate. He finds the dog but the owner is no longer there.
At school, Ms. Blake finds Derek waiting in her classroom. She picks up a wooden pointer and wields it awkwardly as a defense. She fears he is there to intimidate or kill her to keep her silent about the events of Fireflies. She reveals that her name is Jennifer and that she has been in psychotherapy. She and Derek discuss "The Crucible" - a Play by Arthur Miller. Derek explains that it's an allegory for McCarthyism. She promises to never tell about what she's seen and seems nervous but intrigued by Derek.
Stiles is wondering if the latest missing guy, Bullet's owner, was a virgin. Scott jokes that he's not because Deaton makes him have sex with all his clients. He says it's a new policy at the Animal Clinic. Stiles gets upset pointing out that if the killer is after virgins that he is in danger and needs to have sex immediately.
They are in the locker room and are overheard by Danny who says he'll do it and that Stiles should come by his house around 9pm and plan to stay the night because "I like to cuddle". It's a joke of course but Stiles believes it just long enough to feign hurt feelings when Danny laughs and walks off.
Isaac returns to school and Coach Bobby Finstock welcomes him and explains that participation on Cross Country team is mandatory for all lacrosse players because he doesn't want them to get fat in the off season. Nike apparently provides the school's Cross Country uniforms and gear.
Outside, a few minutes later, Isaac is lacing up his running shoes. The Alpha Twins, Ethan (in black) and Aiden (in burgundy), stalk up to him on either side. When the whistle blows, everyone starts running with the Alphas way out in front Haliegh follows close behind Aiden.
Scott tries to get him to wait but Isaac chases after them. He loses sight of them again until one pushes him off the trail and down an embankment. They subdue him and are about to beat him when Scott shows up and punches Ethan hard, breaking his jaw. All five wolf out and prepare for battle but are interrupted by a scream.
Running to find the source, they reach a group of students surrounding the body of Bullet's owner. He has been killed in the same manner of the other three, throat cut, bludgeoned and strangled with his dog leash.
The Sheriff arrives and takes control of the scene. Scott reveals that the victim was a senior. The victim's girlfriend, Ashley, arrives and starts crying.
Isaac is convinced that the Alpha Twins knew something about the murder. Stiles believes the killings don't involve werewolves "a lack of werewolfitude". Scott is caught in the middle but believes both sides make good points. Isaac says he's convinced the Alphas are responsible and he plans to kill them.
Derek's sister Cora is working out in his loft. She does pull-ups then drops to the floor doing push-ups. There is tension. Derek tells her to stop because she is not done healing. She refuses saying she plans to go after the Alphas. Derek kicks her hand out from under her and she tumbles to the floor. Cora is livid saying she came back to town because she heard about a powerful new Alpha, one of the Hales, and that she had been waiting for this kind of news for a long time. She apparently did not know Derek was still alive either. Haliegh walks in and hugs her Aunt tightly.
An alarm sounds and Kali and Ennis show up and the five begin to fight. Ennis quickly subdues Cora and Kali beats Derek into submission before stabbing him through the lower back with a steel pipe.
Deucalion enters and begins explaining what he wants. Derek assumes he wants to kill him but Deucalion seems offended saying "Don't throw me in with sociopaths like your uncle". He says he is always on the lookout for new talent and wants Derek to join his pack. Derek says he wants him to kill his Betas but Deucalion corrects him saying he only wants him to kill one and then he'll want to kill the rest.
Deucalion explains how he accidentally discovered that killing one of his Betas allowed him to absorb their power. Once he became blind, one of his Betas felt he was no longer able to lead so he tried to kill him and take control. Deucalion bested him, killed him, and found that he became faster and stronger because of it. He says Kali and Ennis have both killed their entire packs. Kali says it was liberating. Deucalion says Derek's pack, a couple of maladjusted teenagers, are bound to become a liability.
