Dick - 10 Jason - 15 Cass - 14

Chapter Twenty-nine: Pushing Buttons

One thing Cass never quite understood about her brothers, was the way that on one day the two of them would go out of their way to do really nice things and sweet gestures for each other, only to then turn around the next day and do everything in their power to make the other miserable. For example, Jason spent a good three hours helping Dick install a special shelf for his stuffed animals so they wouldn't crowd his bed anymore. The two of them then sorted out the animals based on the stories Dick would tell when getting them with Jason even adding in small facts he remembered of their backgrounds that his little brother supplied him with just a year ago. Now three days later, Dick was screaming at Jason from down the hall, red-faced and teary-eyed, because Jason sabotaged the shelves to fall the moment Dick opened his bedroom door that day, . . . Jason's reason? He was bored.

And it wasn't like Dick was a guiltless victim in these fights either. With the way that Dick had reenacted scenes of Jason's favorite action novels with him, only to then turn around and turn the hero into a 'fart monster', to Jason's irritation, and proceed to raspberry in his older brother's face at least five times every minute. This caused Jason to try and deck him and Dick dodging him gleefully until Jason finally got a good hit in. Bruised cheeked and teary-eyed, Dick told on Jason to get his older brother in trouble despite being the one to provoke the violent teenager. Once Jason was suitably punished, being forced to wash the dinner dishes, Dick kept bounding into the room and blowing a raspberry at him every time both adults were absent.

The two would go back and forth and Cass had to wonder why after so many times of being betrayed by the other, they still would end up laughing and playing games or enjoying activities together, knowing that it would only be a matter of time until one was laughing at the others misery. Then one day Cass found herself in possession of a bag of colorful rubber-bands that she had somehow acquired at school.

Jason was sitting on the couch in the living room, reading Little Women while Dick was behind him in a chair watching TikTok videos on his phone. Cass looked at the both of them and couldn't help but notice that neither of them had their guard up, both so absorbed in their chosen entertainment. Her eyes zeroed in on a spot just behind Jason's ear, unprotected and oh-so-sensitive. The bag of rubber-bands weighed heavy in her pocket. She wasn't sure what drew her hand into the pocket, but she felt her fingers fiddling around the colorful bands in a contemplative manner. They were so trusting, especially of her. She didn't know why, really, but she felt that it was a mistake that required punishment.

More watching herself than actually taking an active role in her movements, Cass pulled out a blue rubber-band, stretched it around her pointer finger and thumb, letting the tension grow as she spread the two fingers, before dropping her thumb and then her arm.

"Ow!" Jason slapped a hand to where he was flicked in the ear, turning immediately in his seat to glare daggers at Dick who only just looked up in shock from his phone. Seeing his older brother upset at him, Dick pulled his earphones from his head to try and figure out what just happened. "The hell was that for?"

"What was what for?" Dick asked looking desperately confused. Jason gave him a scrutinizing look, his narrow eyes taking in his phone, the earbuds, and his full hands.

He took a calming breath and huffed, "Nothing", and resettled himself in his spot, lower this time. He would no longer be an easy target, his guard now up and defenses secure.

Cass looked over to Dick who met her eyes with confused ones. He shrugged and went back to his phone, replacing the earbuds and going back to his videos, too easy of a target. Taking a shot at Dick would only confirm herself as the culprit. She did not what to be found out. But she wasn't done. She had to do it again. She looked back to where Jason was seated. Cass could easily shuffle just a little to the left, and she would have a clear shot of his knee. She felt a twitch at the corner of her mouth.

Her hand back in her pocket, Cass controlled her expression and readied another rubber-band, yellow this time. Just as before, launching it from her two fingers and dropping her arm and looking straight at Dick as Jason jumped up from the couch, hand to the location of the hit. He looked at Cass who was looking at Dick.

"Okay, you're dead," he growled. Dick looked back up, confused as ever as Jason launched himself at his younger brother.

"Hey! What did I do?" Dick cried out, only just getting out of the way as Jason landed on the chair. Jason was graceful enough to land with a knee to the seat grabbing the back of the chair with his hands, lifting it as he threw his weight to his other leg, and swinging the whole piece of furniture at the ten-year-old. Dick dodged only to get too close to where Jason's legs were. The teenager then kicked his brother in the side.

"Ow! Quit it! I didn't do anything!" The child whined.

Cass decided to finally give away her game, pulling another rubber-band out, this time aiming the red band with both hands and snapping it at Jason's neck. The older boy froze in shock before looking over to his little sister with a look of betrayal that caused a bubble of glee to surface in Cass' chest. Suddenly a devious smirk grew along her face without her consent as the boys realized what had happened.

"Cass?" Jason asked, his voice small with the weight of her deceit. Dick seemed to suddenly understand what was happening, turning an equally baffled expression to the girl. They watched as she pulled yet another rubber band out and shot it right into Jason's face, nailing him between the eyes. As the second blue band bounced off, Jason seemed to come back to himself glaring at her with all the righteous indignation that he had wrongly aimed at his baby brother. Dick seemed torn between laughing at Jason's pain and being upset that Cass had let Jason think it was his fault at first.

He was forgotten, however, because Jason dropped the chair to run after Cass, who in turn ran out of the living room and up the stairs. Half-way up she turned just long enough to snap a green band at him again. A giggle bursting from her lips as it hit. Jason was stronger than her, and he knew better than to assume she couldn't take a hit. But she was faster than him, meaning it was going to be a while before she had to face the consequences of her actions. This meant she had no real reason to cease her actions.

Bruce was in his study looking over some paperwork Lucias had sent home with him after he fell asleep in another meeting. His own fault, but still he felt it was a bit harsh. He was having trouble focusing on the dull details of the finance reports when he heard a deafening shatter from the main hall. Shooting to his feet he ran out to see all three of his live-in children frozen around the chandler that had managed to collapse to the ground in the middle of them. Pieces of crystal and glass from the bulbs littered the floor around the ornate hunk of gilded metal.

Looking at all three of the children, they seemed to be standing in similar states of shock; mouths open, eyes wide, bodies tense and straight. Cass's hands were folded over her mouth while Jason's were in fists in front of himself in a defensive manner. Dick was holding the doorway of the living room with white-knuckles, his feet in position telling Bruce that he had only just been leaving that room as the chandler fell. This meant that though he was typically the most likely culprit, this time he was undoubtedly innocent. Since Cass was never in trouble, Bruce sent a look straight for the eldest child in the room.

Jason looked up at him to see the look and balked at the assumption.

"I didn't do that! She did!" He shouted as he jabbed an accusatory finger at his sister.

"And how did Cassandra manage this?" Bruce pursed his lips and raised a brow, lowering his voice an octave to make certain the teen knew he doubted his story.

"She jumped on it to get one of her dumb rubber-bands back!" Jason 'explained'.

"Her rubber-bands,..." Bruce trailed off, he glanced back at the mess on the ground to see there were indeed, no less than thirteen colorful rubber-bands caught within the swirling pattern of the metal. He glanced up to see where the chandler broke off, noting there a couple more somehow wrapped along the now broken chain.

"Cass was shooting Jason with rubber-bands, but Jason thought it was me and hit me with a chair, then she shot him in the face with one and he chased her throughout the house!" Dick narked on both of his older siblings with one breath, getting matching glares from each of them.

"Cass," Bruce turned a bewildered stare to the, usually, well-behaved child. "Care to explain yourself?"

Cass looked over to her adoptive father, then to her two brothers, and then back to the mess on the floor. Her mouth opened and closed a couple of times and she just shook her head and shrugged in a confused way that she had no doubt picked up from the two boys in the room. Bruce watched as her eyes steadily grew wetter and redder before a tear slipped down as she tried to find her voice.

"I- I- don't, I-" She looked back around the room as if hoping for someone to rescue her from the awkward position she found herself in. Jason was the one to break the silence.

"Pfft- haha HAHA!" Jason was instantly a fit of snorts and giggles, landing on his knees and bent over as he howled. "She was bored! HAhaha!"

"Jason, this isn't funny, someone could have gotten hurt," Bruce chided.

"Oh come on! We're finally turning Cassie into a real girl!" Jason barked in glee, pointing to his sister again. "She's really becoming one of us now!"

Seeming to suddenly see what Jason found so funny, Dick started to snicker as well before both boys were cackling like hyenas. Cass was so confused that she couldn't bring herself to laugh with them. In fact, she had the distinct impression they were laughing at her at the moment. Curling into herself, Cass started to sniffle and bite at her lip.

Bruce sighed and put a hand to her shoulder, causing the girl to jump slightly. "Cass, go get a broom. You're grounded and I want all the rubber-bands picked up." He then turned to the overly amused boys before clearing his throat. "And since you both seemed to find it so funny, the two of you get to be the ones to take the chandler out to the dumpster." That only calmed the boys' chuckles slightly. They shrugged and began to get to work. Cass went to find a broom and Bruce heaved a sigh at the damage done, wondering how he was going to explain this to Alfred.

Cass was almost done with her sweeping when she heard Dick shouting complaints from the outside. She walked over to the window to see her brothers wrestling around the metalwork they were supposed to be disposing of. She narrowed her eyes at the memory of them laughing at her. And then she smirked. Oh, how her brothers shall pay, . . .

A/N: So, This might have maybe shoulda gone before 'A Call For Help', but eh, oh well. Here is Cass learning to be a troublemaker just like her family and realizing the bonding power of being just a little mean to each other.

R&R if you liked. (Need a default response? Just say 'OMG Cass!'. I'll take it.)
