Bruce falls in love easily.
He jumps headfirst into romantic relationships often, and is quick to return the moment someone he previously dated implied they might be interested in a rerun. He meets a pretty lady that is fully capable of kicking his ass and suddenly his heart beats for her. Just as easily, he will fall for the next man that he finds his empathy reaching a little too far for.
It’s even easier with kids. He holds a baby, waiting for the baby’s parents to return from being checked over by medics, and he’s imagining them growing up, decorating their nursery in his mind, picking out colleges that’ll more suit different interests - if the baby wants to be a lawyer, then this school would be better; if a little artist in the making, then this other school is the best of the best. And it all goes through his head in the ten minutes that the parents are held up for. He saves a toddler from a burning building, and sees himself taking the kid for walks and building Legos with them. He finds a teenager in trouble, and he’s already imagining helping them with their homework.
Usually, it doesn’t go anywhere. He brings the kid somewhere safe, usually reuniting them with their parents, and then mopes about the loss of that potential future for a few days before it leaves his mind again.
But sometimes, sometimes, a child sticks in his mind. Dick was the first of those children, quickly brought into his custody but not quick enough.
Next was Tim, a bright little child that Bruce noticed before he’d ever adopted Jason. Tim was the first child Bruce had to learn restraint for, telling himself that he couldn’t monitor this little kid who looked at Bruce like he hung the stars in the sky. Still, he couldn’t help but to keep an eye on the little Drake during galas and gatherings. Tim was Bruce’s son before he was ever Robin, no matter what Bruce had said and done in his grief.
Jason was very quickly adopted, Bruce hadn’t even needed to use his hard won restraint for that one. The moment he’d seen those defiant blue eyes glaring at him in the darkness, he’d emotionally adopted the boy. Mentally adopted him shortly after, with the adoption papers filled out and turned in quickly after.
The only child Bruce would find himself counting when doing roll call only to be disappointed had barely been in Bruce’s presence for five minutes. The little boy Bruce found himself thinking often of, wondering how he was growing up, whether he was going to see the stars as an adult like he’d claimed, hoping Bruce might even see the little boy applying for Wayne Enterprise’s Aerospace division. Danny Fenton was a child that crossed Bruce’s mind often despite not being, on paper or by blood, Bruce’s child.
But to Bruce’s heart and mind? Danny should’ve grown up with him.
“Daddy!” Bruce looked down as a small weight hit his leg, stunned to see a small child there. “Look! Shtarsh!” A small lisp, as the child turned a gap-toothed grin up at Bruce. Bruce followed the little boy’s pointing finger, noting that there was indeed a display of stars, the infographics claiming a better way to fuel rockets was such-and-such method over the common-
Wait, had this child called him-?
“It sure is, bud,” Bruce agreed, kneeling down to be closer to even height with this… four-year-old? “But what are you doing over here by yourself?”
“Mommy d’ere,” the little boy pointed towards a woman in a teal… hazmat suit(?), focused intently on the display in front of her. In her hands was a leash that led down to an abandoned backpack.
Bruce’s face twitched at the fact that she hadn’t even noticed, and he didn’t know how long the child had been free of the backpack. Long enough for it to look like it’d been dragged from a different exhibit.
Bruce looked back at the little escape artist, “May I pick you up, chum?” The little boy’s eyes brightened, excited.
“Rocket!” He bounced a little on his toes, hands held up excitedly.
Bruce was disappointed, himself, that he had no clue what this boy was asking for, “Not right now, but maybe later.” Bruce was quick to tack on the last part as the boy deflated. Propping the little boy on his hip, he made his way over to ‘mommy.’ “Excuse me, ma’am- ma’am?” It took several calls, and even waving his hand in her eyesight, to get the woman’s attention - and Bruce’s displeasure with the woman steadily increased the longer it took. “You appear to have misplaced a budding astronaut.”
She barely even glanced at the little boy before negating his statement, “no I didn’t, he’s right-“ finally, she noticed the childless backpack, her head snapping back to Bruce, “Daniel James Fenton! I told you to stop taking your backpack off!”
“But- but shtarsh, mommy!” The little boy indignantly argued back with the woman, and Bruce had to quickly school his face to not smile at Daniel’s attitude.
“That doesn’t mean you can wander off, Danny,” the woman huffed, before reaching out to steal- retrieve her son from Bruce. “Thank you, sir.”
Throughout the rest of the convention, Bruce caught glimpses of the bright-eyed little boy with his mother and father, who was a man that Bruce could feasibly understand the young child confusing Bruce for… if he weren’t wearing an eye-piercing orange hazmat suit, and Bruce a tailored three-piece.
When it became clear that Bruce’s attachment to the little boy didn’t fade with time and distance the way it normally did, he allowed himself just one day in a year where he would indulge, letting himself use the resources available to him to check on the little boy. Last Bruce had seen, little Danny, who had just turned 14, - only a couple years older than Damian now that he thinks about it - was doing well in school and was on his way to becoming an astronaut.
Why was his little boy standing before Batman in dirty, ripped up, bloody clothes and an unnatural green light in his otherwise dull eyes?
