I am so sorry for taking this damn long to add to the story; I wont make any excuses, just update you on what's happened so far -
Gale has convinced Mercy to accompany him back to District 12 and have her bleeding head looked after, and has just sent his mother to fetch Emily [Katniss's mum] to come and fix up Mercy's wounds.
So sorry again, hope you enjoy anyway.
"This woman you have... sent for; she is tru... trustworthy?" Gale nodded quickly at Mercy's hesitant query.
"One of the most trustworthy people I have ever met. Don't worry, she won't tell a soul about you." Mercy bobbed her head up and down slowly, her eyes drifting shut.
"We're going to be okay Watena;" she muttered to her precious doll "no-one will find us here." With a last attempt at a smile, her hollow cherubic face fell slack and her blood drenched head dropped back onto the couch back. Gale waited until he could hear her minute snores – more like a cat's purr than anything – before backing into the room that he shared with his little brothers Vick and Rory.
With a deep sigh, Gale closed his murky grey eyes and leaned his forehead against the thin wooden door, his hands dangling at his side like a puppet free of its strings. Straightening himself up to his full height he ran his long fingers through his already mussed up dark hair.
"Oh Katniss, if you could see me now... what the hell would you say?" His shoulders lifted momentarily in a silent laugh, a tired smile tweaking his lips. The smile left his face as quick as it had come though; Gale thumped his head quietly against the wall and sighed again. Hearing Mercy stir in the other room, he squared his shoulders, shook his head and opened the door to reveal the dozing girl.
She had curled herself up into a loose ball, her impossibly thin arms wrapped around her pulled up knees and Watena nestled gently against her chest.
She looked so peaceful laying there that Gale almost regretted having to open the door to allow his mother and Emily in.
The moment Emily was through the door she was all business.
"Where is she?" She asked, the command unmistakable in her usually shaky voice. Gale stepped aside, and she was at Mercy's side in seconds, her skilled fingers flitting over her, checking for extra injuries. When she reached her bloodied head, Mercy frowned and groaned in her sleep. Gale held his breath as Emily shrugged and called out – "Prim, bring the scissors please." Prim – Katniss's small blonde sister – hurried forward, extending the rusting scissors towards her mother, her cherubic face halfway between fright and seriousness.
Taking a handful of Mercy's bleached tresses; Emily made to cut it off. She didn't get that far however – as if suddenly sensing her presence, Mercy lashed out with her fingers curled into a rather effective rake, scraping her long ragged nails across Emily's face before she could pull herself back.
Gale was on her immediately; pinning her arms to her sides and telling his mother to get a good hold on her legs. Hazelle did as she was instructed, albeit a little tentatively.
Just in time, too; just as Hazelle had secured her grip on Mercy's legs, said sleeper started thrashing around wildly, moaning and screaming at some unknown horror that only she could see.
"No!" She screeched "Leave her alone! Stop it! STOP IT!" Her eyes remained screwed shut, but she kicked and bucked and struggled with all her might to break the bonds that were restraining her – physically and in her mind.
"Leave her alone... please..." Her broken sobs began to fill the air, and Gale thought he heard Prim take in a deep, shuddering breath behind him. Mercy had finally stopped her struggling, now so limp she could have been dead but for the ragged rise and fall of her chest and the steady flow of tears and blood.
