It had been almost a month since Cas and Dean 'recieved' their children and all seemed well. Each personality became obvious in a rather short amount of time, Mary was very adventurous and was already attempting to crawl around on her oddly short legs. Gabriel, much like his namesake was tricky and smart, already learning how to read at an insanely young age "All angels learn at accelerated speeds" Castiel told his husband. Bobby was rather shy, and often clung to Gabriel, though the smaller boy did often disapprove what the other was doing.
At the moment, Dean and Cas were taking the kids to Sam's so that they could spend the babies first Easter together. Dean had begun to settle each kid into their carriage Mary in the middle, Gabe and Bobby on either side of her. Thankfully Gabriel had fallen asleep, as rode trips were hell with him.
Once everyone was strapped in, Dean started up the old Impala, Cas in the passenger seat as he decided to ride with them instead of just flying there. Sam and Dean didn't live very far apart, only about an hour and a half away from each other, they were able to get together quickly for emergencies.
As the family drove down the road, Bobby was practically dead to the world with sleep, but Mary simply sat staring out the window absently. Dean was holding Castiel's hand and stroking it gently with his thumb.
Both men heard a tiny mumble from the back seat, the turned and glanced back since none of the babies had yet to say their first words and everyone was excited to hear what they would say.
They looked around to see Mary gazing back, her two colored eyes big and innocent as she opened her mouth and both men tensed in excitement.
"Ange petit" she said in a high, unpracticed voice.
"What?" Dean asked confused
"Ange petit" Mary repeated, Dean looked at his husband in confusion
"It's French for little angel" Castiel said
"Have you been talking French to her?"
"No"
"Then how does she...?" neither men knew what to make of it but simply smiled and applauded the littlest Winchester, such things were to be expected when you have half-angels as kids.
"Good girl, Mary!" Dean said turning back to the road a prideful grin on his face.
"Fosse démon" came a different voice Castiel turned back, to see that Gabriel was giggling and clapping.
"Fosse démon! Fosse démon!" he chuckled. Dean looked at Cas a questioning look in his eyes. Cas gulped a bit,
"It means 'Demon Pit" Cas said, both men grew unsettled when Bobby woke and opened his mouth as a response
"Puissance de trois" Bobby said a grumpy look in his eyes as he turned over a bit and settled back
"Power of three" Castiel translated, turning back to the front as the streets became familiar as the came closer to Sam's house.
"You think it could mean something? I mean, we've only talked to them in English and now they're saying ominous words in French?" Dean used one hand to pinch the bridge of his nose, hoping that this would be the last of the french talking from their children.
Castiel grabbed his hand and squeezed it reassuringly,
"I'm sure it just has something to do with just their grace, nothing too bad" he smiled comfortingly at Dean, who couldn't help but smile faintly in return.
The rest of the car ride happened with no interruptions of creepy french words as all three of them manadged to get a nap in before they arrived at the bungalow, Sam sitting outside on the porch with a beer. Dean had texted his brother about the strange words and they would all be on a close lookout for any words that weren't English.

The day passed, Adam and Don played with their little cousins, nothing went wrong and they all sat on the couch, Gabe chewing at his bottle, Mary sitting on Dean's lap, and Bobby playing with Adam. Cas and Dean decided to spend the night, not wanting to drive back to their house so late. They took the guest room, Mary, Gabriel and Bobby slept in the boy's room.
That night, Dean turned to Cas, who was dressed in his pyjamas, an inquisitive look on his face.
"Cas, do you think that maybe what the kids said... had something to do with their names?" he asked the angel cocked his head.
"I mean, think about it, Mary said 'little angel' and... well my mother used to call me that a lot when I was little. Gabe said 'demon pit' and, well Gabriel did have a lot to do with the gateway to hell. Bobby said 'power of three' and there are three of them, and you know how Bobby was about family" Dean said searching the angel's eyes for a response.
"Perhaps, angels do tend to learn about people very easily, dead or not... Most likely since they share a name, they might have some connection to one another" Castiel said. Dean smiled, feeling at rest and leaned over, gently kissing his husband. They curled up together, relaxing and Dean quietly slept through the night.
That was till they heard a loud screaming come from the kid's room.
