Baby of Mine

-One-

Castiel wrapped a reassuring arm around Nina, the young blonde crying against him as she sat at the roadside with two bags of her life possessions in by her side, one hand resting on her bump as she rubbed it gently. Her step-father couldn't take having to deal with a baby anymore and had thrown her out, but luckily for the blue-eyed beauty, the father of her baby, her angel Castiel had come to the rescue.

Nina was a beautiful twenty-five year old with the patience of a saint and she was sweet, gentle and caring, yet so frightened about the birth of her baby which was due in a mere week. The baby, in reality, could come at any time from now and even past the due date, and they knew they were having a girl. They'd decided to call her Marie, and she'd take Castiel's last name which had recently become Winchester, since Bobby had gotten him some birth certificates and other such things sorted out for when he became human. He'd gained some of his Grace back from God, but then had chosen to fall and be with Nina. So he was slowly falling as he sat with her at that roadside.

"Let's find a motel for you, Nina." He said softly, "I'll call Dean in the morning and he can come and pick us up...you need your sleep."

Nina simply nodded with tears falling down her face, rubbing the bump and leaning on Castiel for love and protection which he gave without question.

"Cas?"

"Yes, Nina?"

"I love you."

Castiel sighed and kissed Nina's forehead. He'd known this beautiful human since she was merely a baby, yet he'd only ever watched her from Heaven. However, she'd always known somehow that he was watching over her. When she was a baby she'd once looked straight at him from her crib, and he'd smiled at her. That beautiful little baby had smiled back at him and reached towards him, and he'd reached back with his Grace, stroking her face gently with it. She'd wriggled around and laughed when he'd done that, but his strokes were soothing and she'd fallen asleep soon after.

"I love you too, Nina." Castiel replied, holding her hand tightly, "Where is the nearest motel in walking distance, my angel?"

"About five blocks away." Nina answered, "My back hurts..."

"I know." Castiel soothed, rubbing her back gently as they moved forwards, him carrying her bags since the poor girl was in no fit state to carry them herself.

They set off walking, Castiel wishing he could just teleport them there, but that could endanger the baby, and he didn't want to risk Marie or Nina for anyone.

Eight Hours Earlier

"Just be prepared for a phone call Dean." Chuck warned, "I don't know what it will be about but I just see Castiel talking frantically with someone holding his hand...the hand looks feminine."

Dean sighed and rubbed the bridge of his nose, thinking about what it could possibly be about.

"Thanks, Chuck." He said, "Anything else?"

"Um..." Chuck replied, the rustling of papers indicating that he was going through notes, "There was crying...and something about Cas promising this girl something..."

"Alright." Dean sighed, "Thanks, Chuck. My cell phone won't leave my side all day."

"The background was dark so I'd say it's coming at night time..." Chuck said, "If you hear nothing from him in the day time, expect it at night. And you need to be in Deerwood, Wyoming...so I'd set off right now."

"Thanks, Chuck." Dean replied, "I'll let you know what happens when we've dealt with...whatever it is."

"Thanks, Dean."

With that the two hung up and Dean sighed, scrubbing a hand over his face.

"Sam!" He yelled, "We gotta go to Wyoming!"

Present Time

Nina was sleeping peacefully on the bed in her motel room. Quite how, Castiel would never know since it felt so damn uncomfortable to sit on. She shuffled a little and that almost nine-month bump was getting in the way of her being any more comfortable and she winced in her sleep, her eyes opening softly before a pain shot through her stomach, causing her to cry out in pain and sit up a little, Castiel going straight to her side.

"Cas..." She breathed, "Cas, I've started..."

Castiel put his hand on her stomach and felt using his Grace, discovering indeed that their child was coming. God had made the baby human, so they could savour as much time with her as possible without her growing too quickly.

"Alright..." Castiel said, realising he wasn't very calm, "Deep breaths now, Nina...deep breaths..."

Nina began to breathe and Castiel started to pack her bag up, wincing as she let out a pained sound through her first contraction.

"Good girl..." He soothed, "Deep breaths now...nice and easy..."

Six Hours Later

The cell phone began to ring and Dean looked to his brother who was driving, answering it and expecting the panic on the other end of the line.

"Cas?"

"Dean, I need your help, please!"

"What's wrong, Cas?" Dean asked, "What's wrong?"

"My lover...Nina...she's in labour..." Castiel breathed, "Our baby girl is on the way and Nina's getting ready to give birth...we need help! I don't know what to do and Nina's in so much pain..."

Dean swallowed thickly and tried to ignore the screams from the poor young girl who was with the angel.

"I'm so stupid!" Castiel scolded himself, "I...I thought we could walk to the hospital but it was too painful for her...and now...now, we're in some woodland by the Oak Tree Motel...I didn't...I didn't think and...Dean, please!"

"Alright...alright, easy, Cas..." Dean soothed, "Easy..."

He gestured for Sam to speed up and began looking around for the motel, since they'd just entered town.

"Listen, Nina is probably twenty times more frightened than you are...you need to keep calm and be brave for her, because she's about to give birth in the forest for fuck's sake, alright?" He said, "Chuck told us you'd need us here and we're here now, we're just trying to find you both, okay?"

"Follow the screams, Dean." Castiel said, clearly trying to make something funny out of the situation.

The poor girl sounded so pained it was hurting Dean to listen to.

"Dean, she thinks she needs to push...what do I do?" Castiel asked, "She's so scared, Dean..."

"Alright, we're by the motel," Dean said, "We're gonna head into the woods to find you both, okay?"

"Hurry, Dean..." Castiel begged, "Please!"

Dean hung up and he and Sam grabbed weapons, flashlights, blankets and Dean's bag. They didn't know what supplies Castiel and Nina had with them, if any at all so they had to be prepared. And sure enough, in the distance there was the sound of crying and the occasional scream, both of them running into the woods to try and find the poor girl before it was too late.
