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

Oh brother!

Quinn walked into the kitchen grabbing an apple, she turned to see Damian glaring at her "Just because Bruce doesn't care about who your parents are doesn't mean I don't... you are just like them!" He growled and stormed off. Quinn stared at the spot he was just standing at and blinked confused, she felt her throat tighten and it felt like she was being choked with barbed wire I'm just like them aren't I!
I don't find gore gross and my eyes are like there's and my smile/grin! Won't I ever escape them! She thought, she ran to her room and cried into her pillow, she heard the door open but she didn't look up she smelt the aroma of Alfred's cookie. She felt someone sit by her on the bed "Hey Q what's wrong?" Came Bruce's soft voice, Quinn reached out for the cookie trying to find it with her hand until Bruce placed it in her hand, she retracted her hand back under and she nibbled at the treat her sniffles stopped and she turned over but she was curled up into a ball. She looked up at Bruce's eyes as she swallowed the last bite
"What's up princess?" Bruce whispered, although the name was kind of for younger kids and that Bruce wasn't her real dad, the name still warmed her heart
"Am I like my p-parents?" She stuttered, Bruce was caught off guard with the question but his eyes soon filled with concern
"No of course not! Who told you that?" He cried but he already knew because the girls eyes darted to the left wall which led to Damian's room "Look you are not like your parents and I will speak with Damian because you are welcome here and nothing will change that" Quinn's eyes welled up with tears and she placed her head on her adoptive dad's lap
"B-but my eyes and my grin, I don't get freaked out at gore at aged six!... I don't want to be like them" she sobbed, Bruce stroked her hair feeling her tense up, he was going to let go but she relaxed and so he continued.

Bruce was so sad at the fact she was upset because of her parents and he was shocked when she placed her head on his lap and when she let him stroke her head, he eventually found out she had cried herself to sleep and he tucked her in cleaning the mascara on her face with a wet wipe. Now to find Damian.

Bruce checked his room, when he found nothing he checked every other room until he ended up in the bat cave, and there he found the boys playing on their phones "DAMIAN!" He yelled, the boys jumped (and they were supposed to be superheroes!) and looked at the younger child "y-yes" the boy stumbled Bruce was usually calm so when he got mad he was scary " I was walking past Quinn's room and heard her sobbing! She was upset because she felt like she was like her parents! I figured out that you had put that thought in her head, she cried herself to sleep. Now do you care to tell me why you would tell her that?!" He cried, the others boys looked at their brother shocked
"You said what?!" Dick cried, Damian rolled his eyes
"Look her parents are villains so she must be! What do you think villains teach their kids! Not to be nice" he growled, his brothers shook their heads they had had a new sister for a week now and she felt like family and here Damian was making her cry herself to sleep!
"No she's different, if she was so evil why would she be sobbing?!... Now it's time for dinner" Bruce growled, the boys snuck out of Bruce's office and sat around the table as they waited for Quinn, after about 2 minutes she slumped down the stairs she had tear stains on her face and her hair was in a messy bun, she was in her pyjamas (basically black leggings and a tank top)
She avoided people's eyes as she sat in between Alfred and Dick ( Alfred can sit with them because he's a boss and Bruce has a heart, and knows not to mess with him)
"So Quinn I was thinking you could go to school with the boys" Bruce said poking his steak, Quinn spat out her half eaten potato on to her plate "it won't be that bad!"
".....I- wh- to- gah Okay, I guess" she agreed reluctantly know there was no way out of it
"And it's a public school! So no rich kids well... there are a few" Dick cried a smile on his face he started to rant about hundreds of things about the school and Quinn was flustered so she grabbed his hands and spoke slowly to him "calm down"
Everyone looked at her and then her hands that were holding her brother's "What?!" She cried
"You um...physical contact! With my hands" Dick explained, Quinn looked at her hands frowning
"Oh yeah did I forget to tell you" Bruce said innocently
"You knew!" Tim cried but a grin was on his face Bruce looked at his food and proceeded to shove it in his mouth leaving Tim waiting for an answer
"You can still nod" Jason said, Bruce face palmed and swallowed the food in his mouth
"Yes I knew when she was upset she put her head in my lap and let me stroke her head" he explained
"I think it's because I know you and your my family so... I don't think it's the same with other people" Quinn said quietly.

The boys had to go out on parole so they told Quinn it was a small business thing, but they left Damian because of his outburst to Quinn.
Damian was sulking in his room when he heard screaming from the room next door, he rushed into Quinn's room to find her thrashing in her bed he ran over and shook her, her eyes snapped open and looked around frantically "hey you're ok now" Damian said his voice tense
Quinn calmed down and looked at the boy after a long long silence with them examining her room Quinn Built up the the courage to ask "why do you hate me?" She whispered the boy slumped down on her bed
"... gah! I-I don't hate you,I'm just very protective of my family and I don't want anyone to hurt them because I love them, don't tell them I said that!" he confessed Quinn raised an eyebrow the concept of a family loving each other odd in her mind was odd
"I would never intentionally hurt them Damian I promise" she said, Damian nodded
"So- Sor-.... Sorry" he blurted after trying to actually say the word without gagging (apologies aren't his thing)
"How about we watch a movie?!" Quinn suggested
And that's how they ended up asleep on the sofa with Damian's head on Quinn's shoulder. Little did they know when the others came in they saw them
