3rd POV

Isla sat huddled in the corner of her room. No, it couldn't even be classified as a room. She was huddled in the corner of the basement, her face covered in fresh blood and bruises from her 'sisters' training. She perked her head up as she heard them coming for round two. The basement door slammed open and in ran Isla's 'sisters', Yang and Ruby. Behind them was her 'dad', Taiyang. "Ready for round two girls?" He asked.
The two monsters by his side grinned. "Yeah we are!" They yelled, running over to Isla and getting ready to fight. Taiyang strode over and punched her in the face, breaking her nose. He then backed up, letting the two little monsters have a turn. Ruby kicked her in the stomach, causing Isla to hunch over in pain and roll into her side on the basement floor. They then began to harshly kick her repeatedly, yelling things like 'Mistake!' 'Burden!' and 'Why did we even keep you!' That last one made Isla think back to around seven years ago.

Flashback

Summer opened the door after hearing someone knock. She saw no one there, when she looked down she saw a little faunus girl, her clothes and hair matted and dirty. She was holding a note that read, 'My name is Isla, please take care of me.' "Aw, you poor thing." She said, picking the girl up. "Let's get you inside." Summer took the girl inside and every one greeted her with warm smiles. But alas, that was all a facade. Within a month Isla went from being the centre of attention and loved by all, to being ignored and neglected. She went from having delicious meals cooked for her, to cooking for the entire family and getting yelled at if it wasn't perfect. Days went past and the beating got worse. Day after day she was used as a punching bag by Yang and eventually Ruby.

Flashback over.

It was well after the three had left, almost time for dinner. Sure enough, Isla heard Yang yell from upstairs. "Isla! Get your lazy ass up here and make dinner! I'm starving!" So up she got. She walked up the stairs, barely dodging the plate thrown at her head. She grabbed the step stool, yelping as stood on her tail, and dragged it over to the kitchen. Some time later she served the meal, after getting yelled at for taking too long. She ran back to the basement, tripping on the last step and falling face first on the floor. She lay there for a few minutes, sobbing harshly, thinking of what she could have done to deserve the abuse and neglect she had been through for years. Eventually, she decided on something. She was going to run away! She stuffed what little belongings she had, mostly Yang's old clothes, into a backpack, and waited. After a while, Isla made her way up the basement stairs and peeked through the door. No lights were on, indicating that no one was awake, not even that drunk, Qrow. She creeped into the kitchen, were she knew they kept their lien. She grabbed all of it and ran, not even bothering to leave a note. They won't miss her anyway.
