Marinette was so glad to be back. After a month long mission away from her family and friends, she was back home in Gotham. She entered the Manor with a smile on her face and grinned as she saw her husband in the kitchen, his back to her.
"Damian?"
He turned around to look at his wife which tired eyes, although there was a strange bundle in his arms.
Marinette raised her eyebrow, "Did Bruce adopt another kid?"
Damian rolled his eyes, "Not another, no."
Her eyebrows rose, "Oh so he always had this baby?" She quipped back.
"In a way. Here, take him."
Marinette shook her head and grabbed the child being trusted at her while Damian scurried off, only to come back wearing a papoose with another baby in it, pushing a twin baby buggy with two other children in it. Marinette's eyes grew incredulously.
Her exasperated expression only grew when Alfred followed, also wearing a papoose and pushing a twin buggy.
"What the fu-"
Alfred's sharp eye glared at her.
"-dge?"
Damian sighed, "They got hit by some Youth Ray or something. I don't know, I haven't slept in days. I've been trying to fix it."
"What do you mean 'Youth Ray', who are these babies?"
She looked down at the child in her arms only to notice a Nightwing inspired onesie on him.
"Oh," she grinned, "Don't tell me you actually went out and bought them their own costumes."
Damian looked as if his hair was falling out, "It's the only way to tell them apart. Why does he have to adopt children that look exactly the same?!"
"Please tell me you took pictures."
He glared at his wife, "Do you take me for a fool?"
…..
Weeks later, after the whole Batfamily returned to their normal states, Bruce almost cried when he realised how many baby pictures he now had.
He actually cried when he realised he couldn't tell his own children apart.
