Batman adopted joker's kid!(DC &OC)

Seriously?! Kidnapped again

Quinn let her friends through the door led them to the kitchen with her crutches, where the ingredients for pizza were laid out on the counter
"Where's grey?" She asked as she grabbed some juice
"He'll be here soon I told him you wanted to show him something" Miles answered and took the juice from her hand
"Why you little-" but she was cut of by the bell, Miles chuckled as he hid behind Scarlett and Quinn hobbled to the door
"Saved by the bell!" She called over her shoulder
As everyone hid behind furniture
She opened the door to see grey smiling at her
"Hey Quinn what is it you wanted to show me?" He asked and she took his hand and pulled him inside
"Quinnn!"he whined but then everyone jumped out and yelled "surprise!' And he shrieked

The party was going great! Quinn had just finished the last song when her brothers came running in with Damian holding Quinn's sword and holding Jason at sword point whilst Jason held Damian's knives, Tim and jack were yelling at them to calm down
"BOYS! What the hell is goi- hold up.... is that my sword?!" She yelled and they stopped
Damian turned pale and tried to hide it but she already knew he had it, she ran at him as fast as she could with her crutches which was surprisingly fast and pinned him to the floor ignoring the pain in her leg
"Don't steal my weapons!!" She shouted before dragging the boys out by the ears and hitting them with her crutch.

Four hours later

The others had gone home leaving Quinn and Miles who was helping clean up
"You sang really well" Miles said as he shoved some paper plates in a black sack Quinn blushed violently
"Thanks! You did Great too!" She said and they looks at each other for long while
"You know I'm thirsty" she chuckled nervously and grabbed them both a drink.
They continued to clean up when they both got dizzy. Quinn's tongue felt heavy and her eye lids were weights pushing her eyes closed. She felt herself sway before she
collapsed onto the floor and Miles fainted on the sofa.

Quinn woke up and felt a pain in her head, she got up slowly to find she was in a dark cell with a stone floor that had bones in the corner, she shot up onto her feet but immediately regretted it  when white hot pain shot through her leg and she fell back down, she looked around and saw a figure in the corner, she crawled over to see it was Miles with a cut lip and a black eye
"Miles!!" She whispered yelled and he started to stir
"Wha-" he started to say as he opened his eyes
groggily but he was cut off when Quinn pulled him into a tight hug
"Where are we?" He asked looking around
"We seem to have been kidnapped" she said casually
"What?! Oh my god! What do we do?!" He panicked
"Just let me do the talking and try not to seem like you care that you could die" she said and his eyes widened
"Batman will find us right!!?" He asked and she nodded before moving towards the cell bars and placed her hands on them and tried to heat them up but nothing happened and she growled in anger before limping back to Miles who was shaking
"First time being kidnapped?" She asked and he looked at her in disbelief before nodding, she shuffled closer to him and he placed his head on her shoulder
"We're going to be fine" she soothes him whilst playing with his blonde hair

"How nice!" Came a voice an all too familiar voice
There was movement in the shadows and the figure stepped forward but they split into two more people
"Mum, dad... and person i don't know. You were really going for a tangled vibe there weren't you!" She said smirking, the three people entered the cell then Harley Quinn grabbed her by the throat and threw her into the wall making Miles gasp.
Quinn got up and lent against the wall holding her side and a cut on her forehead that was bleeding badly
"So why did you kidnap us?" She asked through gritted teeth and the joker laughed happily
"We didn't want the boy but he didn't leave you alone so we just took him. As to why you're here is because we need to keep you from the aliens because you well....can't be around them." Said the hooded figure who she had realised was the man from the warehouse
"Who are you?!" She yelled and he smirked like Harley Quinn
"Why sis I expected better from you!" He said pulling down his hood to reveal her brother's face that looked a lot like hers staring right back at her.
And that was when her world came crashing down, they left to go get something or other but she couldn't hear... everything was a mess
"My own brother!" She cried and Miles hugged her and she cried into his chest
"He's the guy! That's why there was blood! It was him all along" she rambled and Miles frowned but couldn't say anything before the the cruel family walked in with a trough of water, jack grabbed Quinn by the hair and dragged her to the water and shoved her head in, the water turned green as her hair dye washed out and she felt her lungs burn and her eyes scream, her head was pulled out and she sucked In lungfuls of air but her head was once again shoved under. After about this happening about twenty times she was thrown next to Miles
And she looked up at her brother " w-why?" She whispered and he crouched down and pulled her chin up so she looked him in the eyes
"Because you are a freak... we don't have powers, yet you do which means you don't Belong" he whispered grinning madly and his eyes full of malice ( malice- intent to hurt and cause pain)
