#We are going to pretend Talia had them naturally so Danny can be a supirse

[dcxdpdabbles]

So I've seen a couple of Demon twin prompts that have Danny and Damien knowing and keeping in touch with each other over the years with the Batfam none the wiser (The funniest being that Damien had Danny go and replace him for a week then the two played it off like it had been happening since Damien was brought to the manor. Another good one had Danny quickly dropping off Ellie with Damien leaving him to introduce Bruce to his granddaughter). How would this play out for you? Would Danny have run with Damien faking killing him, would he have just disappeared from the compound (?) One day?

Their mother had given birth to identical twins. Damien was born three whole minutes before Danny, which shouldn't have mattered much but to the Ra's it meant the world of difference.

Ra's did not want to raise more than one hire. He did not believe in spares or succession struggles. He gave Talia the ultimatum,- pick one twin to raise in their ways and give the other up to a civilian family or lose them both and her status.

Talia will never claim to be an angel. She knew that her heart was cold and wrenched as needed to cleanse the world. She was far too selfish to even consider becoming a civilian away from the league.

It wasn't a bad life, in the end, to become a regular civilian but it was not for her. Ra's had many children who were never deemed worthy of being part of his greater plans. He never mistreated them, but ultimately he ignored them and they grew up not knowing the blood that ran through their veins.

Talia herself knew of six siblings- all different ages and races- that she had seen from a distance. Her father would take her sometimes to see them, to be reminded that unlike them, she was destined for greatness.

They were nicknamed as the Lost by one of Father's past heirs. He had died fifty years before Talia's time but he was known for his surprisingly humorous outlook on life. How Ra could stand it, she will never know.

Sometimes Talia pitted her Lost siblings. They would be outlived by their father- as all of his children thus far have been- but they would never know the waste their lives had become. They would never know the glory of battle, the rush of leading an army, or the satisfaction of successful missions.

They lived in a rose-colored world inside a small fish bowl. Her Lost siblings would never know the vast wonder of the world.

Sometimes Talia envied her Lost siblings. Even though they had no real impact on the world, no real importance, they lived peaceful lives. They grew, made friends, and fell in love without fear of being betrayed. A foolish belief but one that seemed almost blissful.

How light would their shoulders be to not have to carry the weight that Talia has known all her life? Weight to be the best, to be the killer her father required, to allow her son to head to a possible death day after day.

None of them had to worry about their children never returning from a mission like she did. That's why she trained Damian so harshly, why she pushed and pushed until he reached perfection. If she didn't, then Damian would be bested in the field and his death would shatter what little humanity she still held.

She had taken Danny- her sweet youngest boy- to America to entrust him to her Beloved. It was only as she arrived on American soil did she realized that Bruce would not be satisfied with only one twin.

He would do everything in his power to get them both. Despite the years he trained with them, after learning their ways and their mission, Bruce did not approve of the League.

He was powerful enough to succeed in taking Damian as well if she gave him the chance.

Talia chooses to not do so. She instead stopped at the closest city that was miles and miles away from Bruce Wayne. She found Amity Park, a small sleepy town that would never gather much attention let alone Bruce's, and located a couple struggling for a second child.

After her men screened them and after making sure that they were harmless despite their eccentric research into ghosts, she gave the Fentons her Danny in adoption.

When she signed the adoption forms, Danny offically became a Lost sibling. She flew home, and held Damian just a tad bit tighter and longer, allowing only a few tears to fall before shutting away her heart.

She visited him through the years, but never within sight. Danny was unaware of her presence, as he stumbled his way with his life. He was unpopular with his peers, uncoordinated in basically everything, and the idea of him harming anything was laughable.

He had too much of his Father's heart but none of his will.

Talia made the right choose in getting him out. He would not have survived long within her lifestyle.

When her sons turned six, Talia had chosen to take Damian to see his Lost brother. She had two motives for doing so. The first was to show Damian what became of those deemed unworthy. To let him see that he had been given the honor of being the twin to inherit all that the Al Ghuls could offer.

The second was so that Damian could see his brother still lived, even as worthless and meaningless as he did so, he was still alive. He would know nothing of their world but he would still be able to walk through a different one.

She hoped but never voiced that he would find comfort in this and maybe even affection for her foolish Lost brother.

_________________________________________________________

What she was not aware of, was that Damian Al Ghul was just as selfish as she was. Once he saw what he deemed as his there was little in this world that would stop him from owning it.

He believed he was entitled to having a connection with his blood brother so underneath Talia's and the League of Assassins' noses, Damian did just that. He officially introduced himself to Danny when he was eight and told him the truth about their heritage.

Danny welcomed him with open arms. Despite being polar opposites in personality the identical twins were the best of friends. Damian always looked forward to seeing his brother for a short visit whenever the opportunity arose.

Danny was always pleased to host him for a weekend and the Fentons were more than happy to have him over. They may not have been able to adopt Damian but he was just as much their son as Danny was.

Damian just wishes he could return the gesture but if he ever had the Fentons over at Nanda Parbat they would all be dead within the first thirty minutes.

It was best to go to Danny.

Then Damian went to live with Father. It was a rough adjustment and he is not proud of his less-than-optimal reaction to Father's adoptive siblings seeing as the Fentons had proved blood is not required to love a child. It took months of getting used to living there before he was comfortable enough to go visit Danny again.

They spoke every night on the phone, however, since he no longer had to worry about traitorous warriors reporting his contact with a Lost sibling. He told Danny everything about the Waynes, just as Danny told him everything about being Phantom.

They just forgot to tell any of the Waynes about him.

Damian offered to have him over now that he knew Father would never harm his brother, and that the other Wayne children wouldn't kill him either. Danny, ever the most mischievous of the two, had a better idea.

"We could prank the family instead." Danny chirps floating above his bed, headphones in his ear as tries to play videogames upside down. He grins at the screen where Damian stares back at him.

Facetiming Danny can be a bit difficult when his brother has a hard time sitting still.

Damian wasn't strong enough to say no to him.

____________________________________________________________

"Master Bruce" Alfred didn't shout exactly but it was a near darn thing that had everyone in the cave tensing up. They all turned to an older man who was nervously gesturing to a screen. "We seem to have a guest"

They gather around the older man, watching as a teenage boy wearing baggy oversized sleepwear rampages through the kitchen in an ill-fated attempt to make...a sandwitch?

"How did he get in?" Bruce demands at once watching the boy pour himself a large cup of milk. His face was turned away so they couldn't see him clearly but-

"What are you all babbling about? That's not a guest." Damian scoffs after pushing his way to the front of the computers. He waves a hand at the stranger and it is conveniently at that exact moment that he turns around gulping down his milk.

It's an exact replica of his youngest. What in the world?

"Demon Brat" Jason starts slowly, hand reaching for his gun. Bruce would be angry by that, except he's not exactly sure that his son is standing with them now "Who is that?

"Obviously it's Daniel."

"Who?" Dick asks

Here Damian actually pauses looking around at everyone in as close to alarm as Bruce has ever seen him. "Daniel. My brother. Do you all not remember him?"

"Master Damian, this is the first time I have heard of your brother," Alfred stressed, the tone just a tad bit off from being upset. Damian's eyes widen behind his mask suddenly looking rather small.

He stares at the butler like he has never seen him properly nodding his head to the Batcomputer. "Check for yourself."

"I'll do it." Tim offers strolling over. With Babs on vacation with her father, he is the best with computers. He will know if something has been altered. A few clicks on the keyboard was the only sound within the cave as everyone stood around in unease.

A quick hiss between his teeth has Tim announcing. "Demon Brat isn't lying."

There on the multiple screens is proof that for the past four years- since Damian came to live with them- there was Danny. The brother with a medical condition that made being a Bat impossible.

Tim even had a personal folder- one he made but couldn't remember making based on his wonderous expression- titled "Angel Brat". Apparently, he and Danny got on like a house on fire. At least according to the files.

"Are you all quite sure you have no recollection of Daniel?" Damian questioned. His stance is protective, tense in a way Bruce has come to know as his son being nervous.

None of this makes sense. The last time Damian was this nervous was the last large Justice Leauge mission when all hands were on deck to fix the timeline-

Oh No.

"Damian, on the last rank 10 mission of the league you were the only one on the Watchtower when Flash shifted us back. Even Alfred was commanding a tank that day." He states waiting until his son nods in agreement. Around him, everyone was equally tense likely realizing the same thing.

"I was not alone Father. Daniel was with me. I couldn't possibly control all those stations alone."

Of course.

"Damian, I'm afraid the last mission erased Daniel from our timeline. I do not remember him."

His son's eyes practically bug out of his head. He swings around in small circles looking towards the rest of the family. His jaw clenched at their blank expressions.

None of them remembered Daniel either.

"We must inform Daniel at once-"

"No!" Dick shouts, cutting him off. There was a slump in his shoulders as he spoke much less sharply now. "If we do that, there is a chance that Time will try to force his existence out. It could.... erase Daniel completely."

"So what? We just pretend to know the kid? Lie to him?" Steph scoffs,

"Yeah as much as it sucks. I've worked with Bart long enough to know that there is a real danger in telling Daniel the truth." Tim sighs running his hands over his face.

"That's fucking great." Jason sneers, kicking a chair. Duke's hands are curled into tight fists, while Cass is looking at Damian with a sad frown.

Damian sneers at them, fleeing into the showers. Cass is one step behind him. Likely for the best, his eldest daughter has always been the best one to confine into. If anyone can get Damian talking about his feelings without being too pushy, it's her.

Alfred remains silent but his posture is stiff and straight. He is equally as displeased as his more explosive children. Not that Bruce couldn't blame him.

His heart has already shattered a dozen times over once Daniel's files have been brought up. He has forgotten his son. Has lost him in a way as close to death.

He flickers through them with the family. Everyone wants to remember as much as possible. There is so much. Daniel has a heart condition that has him attached to a heart pump, his consistently cold and is rarely strong enough to wander too far away from the manor.

In fact, he seems to collapse a lot like his legs just become intangible. Talia isn't aware he is still alive- Damian broke the rules to get him out of the league before his plan execution due to his condition.

Despite all of this, Danny had the biggest heart out of them. He seemed to be the kind of person with an easy smile, and happy pun waiting. He is so gentle that Tim's nickname "Angel Brat" is not just a mirror of Damian's

And Bruce forgot him.

To make matters worse the cave's elevator dings on, and down it comes Daniel himself. He looks exhausted, likely not used to being up so late but he smiles at them all warmly anyway

"Hey guys! Welcome home!" He greets. He rushes forward, hugging everyone with ease that not even Dick has been able to do. His movements are done so naturally that this must be how he greets them every night.

Everyone lets him and he doesn't seem surprised by the fact they return the hugs.

Bruce feels like vomiting as his youngest- Damian is older- smiles up at him. "Welcome home Dad! Love you."

"I..." His words catch in his throat. Daniel tilts his head confused but Bruce pushes through wrapping his arms around him just as tightly. "I love you too son."

"Tell the others you love them too" Daniel whispers in his ear. "Don't forget that they need to be shown through words and gestures too Dad!"

Bruce stiffens, unsure if he should but he doesn't have enough information to deny Daniel anything. If he suspects something is wrong he may zap himself out of existence. He can't let that happen.

He pulls back from Daniel after a moment, and then without giving the others warning, he reaches for the child closest to him. Jason yelps as he is dragged into Bruce's warm embrace. "I love you, Jason."

"Ugh what?" Jason sounds confused from above him- when did his little boy get so tall?- but he wraps his arms around him too, giving the beaming Daniel a quick glance before he mutters. "Love you too old man."

Bruce turns to Dick who is practically bouncing on his heels, arms held out. He steps into them easily, grunting as Dick squeezes him with all his might. "I love you, Dick"

"I love you too!"

Tim is staring with wide longing eyes over Dick's shoulder and Bruce knows he will have to hug him next. Behind him, Daniel has moved to embrace both Jason and Steph, which triggered a group-wide personal hug.

Even Alfred is there affording hugs and I love yous.

It's.....nice.

_____________________________________________________________

None of the Bats are good enough to read the body launage as Cass is. She saw the mischievous glee her new brother was hiding as he went around hugging everyone.

Damian taps her wrist. "Will you keep quiet of Daniel's harmless jest?"

She smiles. "Funny. They think they can't say no to him. "

"Oh, Dad! Now that you're back can I paint your nails?" Daniel asks loudly. "I have the best black nail polish!"

"....I suppose that is fine."

Damian cracks a smile. "My brother is a menace."
