Darkness crept over the bunker once again, the sun had set, and the wind was blowing hard. There was never anything normal when it came to the Winchesters. Trouble seemed to follow them wherever they went. It was why Dean was so afraid to finally admit his feelings to the angel he had known for 8 years, he couldn't' bare it if he lost the love of his life. Of course, coming out to Sam was no surprise as Sam already knew. Mary, was the one who needed her space and time to accept Dean and Cas, but eventually realized her son's happiness was the most important thing to her.
Dean and Castiel quietly wedded away from all the monsters and demons that had haunted them for years. Life was somewhat actually decent in the men of letters bunker until Dean had found Cas crying in the bathroom they shared. "Another Nephilim has come to be" was all that he needed to say for Dean to understand. There was no denying it, and no turning back. Castiel was pregnant. Instead of reacting in the most Dean shouting and throwing things matter he just held his husband in silence for a good 30 minutes so they could both digest what had happened. Mary and Sam reacted the same worrying for Cas and the child, after what they learned from Lily Sunder, but this was far worse since this child was actually going to be half human and half angel.
They amped up the security quite a bit. It was Dean who decided to not let the fears on everyone's mind ruin the so called blessed time for Cas. Dean was the one waking up at god knows when to go get Cas some ice cream, and oreos. Dean was the one secretly bringing him home "maternity" clothes to help Cas be more comfortable as their child grew within him. The little family even held a small baby shower for the expecting parents with nothing too frilly as Dean had wanted. They decided against a nursery because they wanted to know their baby was safe with them, so they just bought a crib.
As with all things, time flew by with Castiel expected to deliver soon. Dean sat outside leaning against baby gazing up at the stars where he knew God his "father in law" had to be. "Look Chuck, please just please guarantee their safety. I don't even see what we have even done wrong! These stupid rules!" Dean shouted, then looked back down at the ground sighing deeply.
"Dean."
Dean looked up to see Castiel, his face serious with two hands over his belly as if to protect their baby. Castiel's blue eyes were glossy with what almost seemed like tears forming in the once hopeful eyes that Dean fell in love with. "You pray with such anger these days" Cas came closer to Dean. "My father is somewhere up there. I have faith" He placed a hand along Deans stubbled cheek, where a small sob escaped him.
"How's the baby?" Dean sniffled trying to redirect the conversation.
Castiel smiled rubbing over the spot where he thought the baby to be "Asleep I think is the word I'm looking for. But I know it will be soon my grace is drained, and I tire much easily. Come back inside with me please?" Cas extended his hand to Dean's. Dean gently grabbed onto Cas hand before kissing it softly.
"Remember when I told you to not ever change? I meant that all those years ago." Dean chuckled wrapping one arm around Castiel as they headed inside.
Once inside Dean felt more at ease. He looked around the den at all the people he had in his life. His mother, who was getting to see her first grandchild, it was always a secret dream of Dean's perhaps it really was going to come true. Sammy sat across the room on the computer, his brother and best friend, the tall Uncle who would teach their kid all kinds of things, and spoil him or her rotten. Dean smiled as the mental images of a little child running through the halls of the bunker jumping playfully onto good ole Uncle Sammy. Then there was Cas, sound asleep in the recliner with his hands draped around their baby. Dean went over to him and just held his hand tight.
"Dean?" Mary asked seeing her son suddenly so somber once more.
"Mom you gotta promise if something goes wrong here, like something happens to me, you take damn good care of him." Dean's eyes were filling with tears again, as Mary went over to hug her son.
"I promise Dean." She gently kissed his hair "You want some pie honey?" She smiled remembering she had a pie out in the fridge.
Dean carefully scooped his angel into his arms "Nah, that's okay Mom we ought to be heading to bed now night." Dean mumbled walking to his and Cas room. Sam stood up and walked over to his Mother. They both watched as Dean carried more than just the burden of a heavy heart, but also the heaviest weights of all; Cas life, and their unborn child's.
