Chapter Text
It started with honey.
Not demons.
Not ghosts.
Not Heaven’s leftover apocalypse trash.
Just… a jar of honey.
Dean woke up early, stretching before glancing beside him. Cas was still asleep—actually asleep, in Dean’s bed, breathing softly like he hadn’t spent the last decade pretending not to need rest.
“Hey,” Dean whispered, nudging him. “For real? You okay, buddy?”
Without opening his eyes, Cas muttered, “Buddy? After what we did last night, I don’t think that’s appropriate.”
Dean flushed crimson. “Okay—my bad. Good morning. I’m gonna, uh… go.”
He fled to the kitchen, because Dean Winchester was brave enough to fight God but not brave enough to handle Cas calling out their sex life before sunrise. He made toast. He poured coffee. He ate honey straight off his thumb.
By the time Cas shuffled into the kitchen—yes, shuffled—in sweatpants, hair sticking up like he’d wrestled a lightning bolt, Dean was finishing breakfast.
Cas froze. Stared at the empty honey jar.
Stared at Dean.
“You ate all of it?” Cas’s voice cracked like thunder.
Dean blinked. “Uh… yeah? Cas, relax. I’ll get more.”
Sam, pouring coffee, muttered, “Here we go.”
“You don’t understand!” Cas slammed his hand on the table, making the salt and pepper shakers jump. “I was saving that. I needed it.”
“Needed it?” Dean raised an eyebrow. “For your… celestial tea party?”
Sam snorted. Cas glared.
“You’re both insufferable,” Cas snapped. “And loud. Sam, your chewing is intolerable. Dean, you keep calling me ‘buddy.’ How either of you survives is beyond Heaven’s comprehension.”
Dean froze mid-bite. “Did he just—?”
“He did,” Sam said, almost proud.
That was Day One.
By Day Three, Dean walked into the library and found Cas on the floor surrounded by chip bags, pickle jars, and God help him chocolate syrup.
“Cas…” Dean whispered. “What in the holy hell are you doing?”
Cas looked up, cheeks puffed out like a furious chipmunk. “You took the last honey. I had to improvise.”
Sam leaned in the doorway, arms crossed. “You’re sleeping ten hours a day, yelling at us for existing, and now you’re binge-eating like you’re preparing for hibernation.”
Cas scowled. “Maybe I would rather sleep than listen to your constant sighing, Sam.”
Dean burst out laughing.
Cas threw a pickle at his head.
By the end of the week, Sam cracked.
“I think something’s wrong,” Sam said as they washed dishes, Cas snoring loudly from the bedroom.
Dean scoffed. “No kidding. He almost cried yesterday because the diner was out of pie.”
“That was you,” Sam said flatly.
Dean glared. “Not the point.”
Sam dried his hands. “These symptoms—mood swings, exhaustion, cravings? Something angelic is going on. And if we don’t figure it out, Cas is gonna smite us for breathing too loud.”
Dean sighed. “Fine. Road trip to Bobby’s.”
Sam smirked. “Road trip.”
Bobby’s reaction was predictable.
“Are you idjits seriously asking for books on angel biology?” Bobby groaned. “What is this, the Heavenly maternity ward?”
Dean rubbed the back of his neck. “We just… need to check something.”
Hours later, Sam had a stack of ancient tomes and Dean was hovering nervously near Cas, who sipped tea like the cup had personally insulted him.
Then Sam hesitated.
And that was never a good sign.
“Uh… Dean?”
Dean looked up. “Yeah?”
Sam pointed at a page, face pale. “These symptoms… irritability, cravings, fatigue… they match something.”
“Match what?”
Sam swallowed. “Pregnancy.”
The room went silent.
Dean choked. “Preg—Cas? You’re telling me Cas is pregnant?!”
Bobby took a long drink of beer. “Gonna need somethin’ stronger for this.”
Cas slammed his book shut. “Impossible.”
Sam skimmed another page. “Nephilim gestation is rare, but not impossible. It requires a… strong bond between angel grace and human soul.”
Dean’s ears went bright red. “Don’t you look at me like that.”
Sam didn’t stop. “It usually happens after—well—you know.”
“Shut up, Sam!” Dean barked. “Cas has a male vessel, so do I. How the hell—?”
Sam pointed at the text. “There are two types of Nephilim births. Female vessels… and male ones. Male pregnancy requires a powerful merge of grace and human soul. Emotional connection. Bonding.”
Dean slowly looked at Cas.
Cas stood up, pacing. “It cannot be happening. Nephilim are dangerous. They bring imbalance. If Heaven or Hell finds out… they’ll hunt me. Hunt us.”
His voice cracked—fear bleeding through the edges.
And Dean’s stomach twisted.
Dean stepped closer. “Cas… hey. If this is real, we’ll figure it out. Together. You’re not alone in this.”
Sam nodded. “We’ll protect you, Cas. No matter what.”
Cas shook his head, voice soft and broken. “You don’t understand…”
Dean exchanged a look with Sam.
Cas wasn’t angry anymore.
He was afraid.
And nothing scared Dean more than seeing Cas scared.
