Castiel just stared at his father and brother. What had he just said? He looked down at his vessel. He didn't look any different. But he did feel a little different. More... Powerful. He couldn't find the right words to speak. When he did, they didn't come out as matter-of-fact as he'd originally hoped.

"Is this even allowed?" He asked, bewildered. Chuck laughed.

"I'm God. I can do whatever I want. And frankly, Dean's idea for this was perfect. We've been short handed since lucifer went to the dark side. Who better to take his place than the angel who helped defeat him?"

"I..." He didn't have words for this. Gabriel clapped him on the shoulder in a congratulatory fashion.

"Don't overthink it, Cassie. Just roll with it."

Castiel gave his brother a look. Then he turned his attention to Dean, who was grinning at him. Castiel put his hands on his hips.

"And I suppose I have you to thank for this?" He said playfully. Dean giggled and ran up to hug him. Castiel easily picked him up and gave him a kiss. "That was very sweet of you to think about me. Thank you, sweetheart."

Dean hugged him tighter in reply.

Castiel grinned and set him down. With a slight pat on his back, he sent him off to go enjoy the party. He stayed back with his father and brother, watching his son interact with everyone. His happy, joyous spirit was infectious, and it transmitted to everyone. Even Bobby couldn't help but smile at him.

Dean made the most of every second of his birthday. He talked to everyone, thanked them for their gifts, and basked in the presence of his family. When it started to get late, however, some of them had to go home for the night. Dean pouted as expected, but said goodbye to each of them and gave them hugs. Slowly, the numbers dwindled down until it was just the four of them again. Gabriel and Castiel made short work of cleaning up after the party, and then they all went back inside the cabin.

It was still fairly early in the evening. The clock on the oven said that it was nine at night. It wasn't quite time for the boys to head to bed yet, but Gabriel and Castiel were ahead of the game and decided to have them go and brush their teeth. After that they could have some wind down time in the living room. Sam watched TV while Dean sorted through his presents and put them away. He put the books Bobby gave him on one of the other shelves in the house, and the DVD from Claire under the TV. He had the clothes and toys Ellen and Jo gave him in the nursery, and some of the new hunting supplies in the trunk of the car and put the tickets from Gabriel in the glove compartment. Finally, he set the picture Sam had given him on top of the dresser in the nursery.

There. Now everything was perfect. The only thing he didn't put away himself were the adoption papers, but he had a feeling his Daddy had somewhere special he wanted to put them, so he didn't worry about it.

By the time he went to sit with Sam, it was barely nine fifteen. He had his favorite blanket around his shoulders and his pacifier in his mouth. He didn't have to go to bed for another forty five minutes, but Cas had a feeling he just wasn't going to make it that long. As if to confirm his suspicions, Dean let out a huge yawn, and his pacifier fell out of his mouth. He caught it before it touched the ground and shoved it back in. Castiel chuckled and lifted Dean onto his hip. Dean whimpered, pointing to the ground beneath him, but Castiel shook his head no.

"Sorry buddy, but it's some birthday boy's bedtime."

Dean pouted, but didn't put up a fuss, much to Cas' relief. He Carried him into the nursery and was about to change him into his pajamas when he realized that Dean probably needed a bath after such a long and exhausting day. Promising himself he would make it quick, he started running hot water and pouring in a cap full of Dean's favorite bubble bath. He helped Dean undress and then sat him in the warm water, handing him a few of his favorite bath toys. It entertained him long enough for Castiel to wash him thoroughly. When he was done he dried him off as well as he could before getting him into a fresh diaper and his favorite pajamas.

He was going to lay Dean in his crib but he clung tightly to his shirt. He didn't want his Daddy to leave, or for this amazing day to be over. So Castiel sat in the rocking chair, cuddling him and singing to him until his eyes fluttered shut. He was very careful to not jostle Dean as he laid him down in his crib. He planted a gentle kiss on his forehead and then pulled up the side of the crib. He tiptoed his way to the door, taking one last long look at his son.

"Goodnight, baby boy." He whispered, so quietly it could have been mistaken for the whisper of the wind. He flicked off the light but froze when a little voice piped up.

"I love you, Daddy."

Castiel couldn't help the grin that crossed his face as he gently shut the door. He went out to the living room where his brother was sitting and sat down on the couch. Gabriel handed him an ice cold Corona beer. Castiel smiled and took it gratefully.

"We did it, Cassie. We finally did it."

They didn't need to speak to know what "it" was. They just clinked glasses and took a long draught of beer. It had been a long and crazy ride, but they had finally made it. They were finally the official fathers of their sons. It didn't matter what had come before, or even what might come after. Right now all was right with the world, and that's what mattered.

"There is no man in heaven or on earth richer than we are. We have it all now."

"That we do, little bro. That we do."
