Ok, let's add some more stuff to this glorious dumpster fire.
Danny was experimented on before. His parents/GIW didn't get to disecsion yet, just in case such a valuable specimen gets irreparably damaged after/during it. We also all remember how Vlad had done different experiments on him a few times. The boy has Trauma about the whole thing.
Danny knew something like this was coming. He didn't know why he knew. However, the harsh whisper at the back of his mind never ceased reminding him that he was different in one way or another.
And his Different never bore a good reaction. His Different was dangerous. It was painful. It was scary. It was riddled with unexplained night terrors and phantom feeling of wounds that were always absent on his skin when he woke up in panic and silent tears.
His Different was something he missed
It was something he feared
It was something he longed for
It was something he hated.
It was a forgotten part of him
Forgotten, just like he was by the family he had called his own and loved dearly.
His brothers looked with hidden mistrust.
His twin spoke with awkward, strained friendliness usually reserved for his slightly more delicate cases.
His sisters tried to hide their anxiety at his unnatural presence.
His father refused to spend much time together. He missed their stargazing night outs...
His family was a family of detectives. They searched. They tested. They pushed. He knew that. He, too, was picking up a lot more than he'd ever let on.
"Hey, wanna come down for a bit? I got a few things I wanted to look through. Bruce wanted your help."
That's why he was not at all surprised when Tim came to his room and, with faux cheerfulness, called him into the batcave. A flatter of hope that this was actually just an invite to the area he grew to love but was barred from recently died down the second it reared its head. No.
It just came to what his every cell dreaded.
Their normal searches were fruitless. They needed to take the look at the source of their headache.
The walk there was long and foggy. He did not remember most of it. He didn't know why he felt this way painpainpainpainpainpainpainpainpainpain but it was ok. He wanted his family to calm down. Besides, it wasn't like his family would hurt him. They loved him even if they forgot.
It's not like his first one
Tim led Danny into the Batcave, sending him another worried glance. Something happened when he called Danny into the cave. A switch was flipped and Tim didn't know what will come after. He wouldn't engage in a conversation. He hadn't blinked in 5 minutes. His stare was never focused but he never tripped.
"B, Danny has gone unresponsive..."
Bruce looked up from the files on his computer. They got some clues to what might've happened and were going to inform Danny about their findings. However, this lost child now stood in front of him like a soulless statue waiting to be guided somewhere.
"Danny?" The kid focused his gaze on him. "What happened?"
"....?" tilted his head questioningly.
That was unnerving. During the while time Danny was with them, he was always full of emotion. He never hid them and was honest to a fault. Cass had confirmed so time and time again.
"Hey, what's wrong, Danny," Dick, already in costume ready for patrol, came up to the teen and placed his hand on instantly tensed shoulder.
"....m not Star.... not anymore" he heard a muffled whisper.
"What was that?" He prodded gently.
"Nothing. I'll be quiet. Sorry."
They were left in heavy silence filled with some kind of unspoken expectation radiating from the new family member.
"When will you start experiments?"
"Will I be allowed to keep my clothes? Can move around the cell? Will I have a cell? Can-"
"Danny, what are you talking about? Why-" Tim tried to intergect into the increasingly frantic but soft questions.
"-I be sedated? Do I have to be conscious?"
Danny's breathing became erratic as many, many questions of the same kind poured out into the air directed at the increasingly more and more disturbed family.
