This is my first Teen Wolf story! I know it's rushed and terrible, but this story idea has been bugging me for ages. It's an AU story where Stiles used to have two sisters (Emphasise on the used to) and I'll try hard to integrate it into the original Teen Wolf plot and make it flow with everything else. Warning: Major character death (kind of?), Suicide, Cancer (I'll add any more warnings to chapters further into the plot)

It had seemed simple enough.

Three days before we had began our shared journeys through memory lane we had received a letter accusing us of stealing the territory of an ancient sorcerer that had fallen into a coma 3000 years ago.

It had proposed a truce for the time being and a meeting had been arranged to discuss sharing Beacon Hills. All pack members must attend it had said.

Upon arrival a few days later nothing had seemed off-putting or particularly alarming.

One step into the house, and everything went black.

"Uuuurgh" They all groaned in unison, as they blinked lazily trying to clear their blurry vision.

Rising himself up on shaky, weak legs Scott took a deep breath and called out for everyone.

"Liam?" He began, his voice croaking from exhaustion

A faint 'Here' could be heard under a mass of limbs that were attempting to wake up

"Malia?"

"Here"

"Lydia?"

"Here"

"Stiles?"

"Aaah shit!" bang "H-here"

"Kira?"

"Here"

"Mason?"

"Here man"

"Jordan?"

"Here"

"Hayden?"

"Here"

"So that's everyone?" Scott finished sighing in relief before surveying everyone for injuries "Everyone alright?" At the pack's affirmative Scott let the last of his tension stop weighing down his shoulders and looked around.

They were in fact in a hospital room of all places, everyone sprawled on the floor starting to pick themselves up.

The walls were painted an ugly light mint green that matched the bed sheets and the overwhelming scent of disinfectant was practically shoved up Scott's nose. The only thing remotely personal about the room was the small stuffed fox that sat on top of the clean hospital pillow on the bed.

"What the hell?" Scott heard Stiles mutter from behind him and he turned round to see everyone up and peering at the little fox. Most of them were sporting curious gleams in their eyes, no doubt trying to understand why they were here.

However Stiles looked sad, as if he were remembering something terrible, mourning some secret loss.

"Stiles? Do you recognise something we don't? Are you okay?" Lydia enquired, obviously having noticed what Scott had. Everyone turned to Stiles, who rubbed a hand across his face to hide his tear filled eyes.

Before anyone could ask a little sob could be heard from under the bed which caused everyone to freeze. Scott got down on his knees and peered under the bed. What he found had a small gasp escape his cracked lips.

A little girl sat curled into a ball.

"Are you alright honey?" Hayden asked from beside him, she had kneeled down to understand why he seemed so shocked and took control of the situation "Why don't you come out, we won't hurt you"

Slowly the small child crawled out from under the bed and stood in front of them all, her chest rising and falling rapidly from panic and her eyes full with unshed tears threatening to fall. She was a beautiful young lady. A blue silk ribbon was embedded within the mop of dark curls covering her head that brought out her bright eyes of the same colour. It did not take a genius to notice the girl was wearing a hospital gown, and no matter how pretty she may be it did not mask the sickly pale tone of her porcelain skin. She turned her head down as she pushed a fisted hand into her tearful eye.

"Lizzie?" Came Stile's voice as he stared at the girl in shock, and of course! How could Scott not have recognised her? But wasn't she-

"Stiles?" The little girl's small hopeful voice came and she looked up and a large grin broke across her face, and Scott could swear it reached from ear to ear "STILES"

And off she went, flying into his best friend and flinging her arms around his neck as he held her close, manoeuvring around everyone to sit down on the bed and rest their foreheads together.

"I missed you. Where were you?" And a choked sound made its way out of Stiles mouth before he physically swallowed it down and smiled at her with adoration before answering carefully.

"I-I didn't know where to find you" He finally said taking in a shuddering breath and squeezing her gently.

"But didn't daddy tell you I was sick?" Stiles kissed her forehead and stroked her hair as she curled into his chest, careful to mind her ribbon.

"Daddy's been busy little elephant; he's been working hard trying to pay for your medicine"

"What about Catherine?" And that brought a new choked sound from Stiles and Scott closed his eyes for a few moments. Oh man, what must be going through Stiles mind right now.

"Cath-Cathy is the one who told me" He responded his hand temporarily halting from stroking Lizzie's brown locks for a moment, no doubt revisiting something for a moment before he carried on.

"Stiles?" she began, peering up at Stiles "Why isn't Catherine visiting me anymore?"

A sad smile played at his lips "She's just confused" He answered "She's finding it hard to keep afloat"

"So she's drowning?" Said Lizzie before she stumbled out of Stiles arms and went under the ugly hospital covers "Good night Stiles"

"Good night little elephant"
