Werewolves From The Grave

It's time again for Lexi to be in bed. Werewolves would soon be out and anyone seen outside would be torn apart by their gruesome teeth.
"Won't you have a taste of blood before you go?" Morrigan, the mother of Lexi, asks but Lexi grunts, disobeying her and heading towards her room.
Morrigan shrugs her shoulders to make Spike, the father, understand how rude their child has been. Morrigan and Spike exchange a weird look which would lead to further conversation or certainly, argument. But, right from upstairs comes an unusual noise which transfixes Morrigan to the spot, but makes Spike skedaddle to inspect the sudden shenanigan.
It's Lexi. She's right in front of her door but making no noise. The noise is only coming from downstairs. As Morrigan and Spike head downstairs, the noise emerges from upstairs. Until they realize they are being tricked, they become confused.
"Morrigan, you stay here. While I go there." Spike says, climbing down the staircases with fearful caution. Slowly peeking at any movement of any object or unseen figures, he tiptoes, and tiptoes.
Facing the wall clock now, he feels a hand wrapping up itself across his neck. He feels goosebumps and craves to be swallowed up by the ground. He doesn't even know when he mumbles that, until he gets a reply. A response that echoes in the sitting room.
"Not swallowed up by the ground, but by the grave." A voice lile a forghon storms the sitting room and stops abruptly. Spike climbs up the stairs to check up on his wife and child and they're both fine.
"What's up with her? What you found out?" Spike asks, but Morrigan only gesticulates until she's forced to say a word.
"... I can't hear you?" Spike becomes befuddled and needs to be sure of what he's listening to.
"...she's...a... Werewolf!" Morrigan yells and then, Lexi turns her face to their angle. Her face is synonymous to that which has been dipped into a pool of blood, and cut asunder mercilessly. Her eyes are white and blank while her nose breathes as though it would stop within few minutes.
"You should have given her blood to drink before she came up here." Spike accuses his wife, Morrigan. And then, Lexi starts to approach, subtly and quietly.
"Didn't I ask her to?" Morrigan retorts with the up-and-down look alongside. "You were there when she bluntly refused to take even a sip."
"What are the ingredients in the...blood?" Spike asks, and his voice becomes shallow at the end of the question. He hates seeing his daughter this way. She had once become like this, but that was many years back. And whenever she tends to turn into this shape, she would be given the blood to drink.
"The blood of wolves." Morrigan tells Spike. "She's near us now. Don't you...think we should run?"
"Run from your daughter?!" Spike asks, disappointedly.
"Do you want to become a Werewolf!!!" Morrigan yells in return. "This girl is not just human. She's a wolf, and she has connection with dead creatures."
"That's how far you know..." A deafening voice disrupts their bickering. "...she's...a... Werewolf...from the grave!"
"Infected by us..." A skull speaks up, showing itself at the doorpost of Lexi's door. "...she has been mandated to bring all human beings and Werewolves from all kingdoms to be like us."
"And..." It finally says as Spike and Morrigan shut their ears a bit to avoid those ears being blocked. "...it starts with you."
Then, Lexi whimpers and runs towards the angle with an unbelievable speed. It's so evident now that she's being controlled. She howls, and howls like a ram about to be slaughtered. Morrigan quickly makes her way downstairs but Spike doesn't move. He won't want to watch his daughter get mad in his absence.
"Get me the blood." Spike tells his wife downstairs.
"It's expired!" She yells back at him.
"How did you fucking know?!!" Spike yells, trying to endure the gory sight.
"It's green, no longer pure red!" She splutters.
Spike moves backwards to avoid his daughter biting him until his back hits the wall and he freezes, expecting the worst to happen. He first of all shuts his eyes and expects to be bitten suddenly but nope, it seems she wants to take him somewhere. Maybe he's gotta get his power from the original source, and not just through Ordinary bites. He frees his hands away from her bloody hands since he doesn't want to be taken to anywhere eerie.
And the wet squelching stops suddenly. Lexi looks at his face directly, looking so surprised, shocked, and amazed. She jerks up her other arm and there's the symbol of infection.
"...can't....can't....I just get someone to explain this to me!!! Huh!!!" He yells. "This is not what I signed up for!"
"It is." The skull at the entrance of her room speaks up again. "Demon Lexi, bring him over here. Utilise your werewolf power, and let's get him here."
And that explains it to Spike at least. She's a Werewolf, and she's a demon. Actually, he and his wife, Morrigan are Werewolves but not noticeable.
They can shift, but only under the blue moon. They can howl and do all sorts wolves do but not so frequently or strongly, accurately, or intensely. They tend to hold back their Werewolf strength for years without losing it, unlike real Werewolves. If they get lost, they'd shift and still be in their clothes while shifting back to the human form.
In short, Spike and Morrigan are light Werewolves that were blessed with a demonic daughter from the moon Goddess. They had no cure for the daughter but to just drain a wolf's blood and feed it to her if that would shed her demon power.
It's the twelfth day of the month, and it's remarkable. Spike is being dragged on the ground by his daughter to the entrance of her room where pungent smell and odorous dead bodies are replete.
At the entrance now, Lexi jerks the door open and the alarm rings.
Spike had had a nightmare, right in his room.

"Spike, shopping today?" Lexi silently asks since she keeps staring at her dad but doesn't get any response. Meanwhile, Spike is shifting into his wolf gradually, all because she is near him.
Another disaster in the town. This has shown that Spike won't be able to control himself once his daughter gets to be with him or anywhere close to him. He would not want to tell her that. She might feel weird or being isolated.
"Why you not answering?" She asks, and wants to tap him but he struggles to talk.
"I'm feeling so dizzy now..." He says and his voice cracks. He seems so savvy to have revealed his voice as such that cracked. Notwithstanding, his bones cracked. "...would see you in your room in three minutes."
Her obedience saves her, it saves Spike too. Generally, it saves them both. She turns her back to him with her mouth wide agape and then walks towards her room without looking back. And since she's not go
