And here is the last chapter.
I hope you'll like it.

It was late at night when they returned to the bunker.

The snowball fight had taken its toll and they were all soaked to the bone, and they decided to take a nice hot shower (which was more difficult than expected for some of them, since the alcohol was still working its magic on them), only to make themselves comfortable in the spacious living room of the bunker.

And now they sat there on the huge, covered with plush sofa which Gabriel had conjured up for them and they laughed and joked, ate Christmas cookies and had just a good time. Main topic of the discussion was of course the Christmas market and how much fun they had there and that they should take Gabriel with them more often, which made the Trickster grin widely, because these words had just come out of Dean's mouth.

Eventually, Gabriel had sit down on the ground and looked at his friends with a twinkle in his eyes and in his heart he felt a warmth that he had almost forgotten. Even if he would never admit it out loud, but that day had done him so good, as it had done no other day on earth. He had forgotten all the terrible events of the past for a few hours. Only friendship and family counted and he loved it to see his friends and even his little brother so happy and he loved to listen to their joyful laughter.

And wasn't it the angels which should give joy and love to humanity?

This thought reminded Gabriel of something and his usual Trickster grin was right back on his face, as he looked at his friends.

"Hey guys, do you know what is missing to make this evening perfect?"

The four friends turned their eyes on him, shook their heads and looked at him questioningly.

"A Christmas Angel."

A snap of his fingers later and loud swearing came from the kitchen, which clearly came from Castiel, because he had left the living room shortly to go into the kitchen to fetch a few cookies.

"GABRIEL!"

Immediately all of them turned their heads to the entrance of the living room...and broke out into vociferous laughter again, when they saw Castiel, standing in the doorway.

But something about him was different...actually everything about him was different.

His black wings and even his halo were visible, and now instead of his Christmas sweater and black trousers he wore a simple white linen cloth (which looked more like an oversized nightgown in Dean's opinion), and in his hand he held a long, golden trumpet which seemed to sparkle in the glow of the Christmas tree next to him.

"What's wrong Cassie? That looks excellent on you," it came from Gabriel, who himself could no longer hold back his laughter.

"Very funny, ha, ha, ha," the younger angel muttered and his cheeks turned pink.

"Hey Cas, how about you play us a nice Christmas song on your trumpet," Dean said, who already had to hold his stomach from laughing so much.

Sam, Charlie and Kevin fared no better and the latter looked as if he would fall off the sofa from laughing way too hard. Charlie desperately tried to take a photo of Cas, but she didn't manage to keep her phone quiet (and Cas was grateful for that).

But it was not long before even Castiel's lips graced a mischievous grin, because he remembered something and when he turned his azure eyes on Gabriel, the Archangel stopped laughing almost immediately when he saw the unusual wide grin on his little brother's lips.

"What's wrong Cassie? Why are you looking at me like that?"

The others stopped laughing, turned their eyes on Castiel, wondering what he was up to.

"If we are already at the Christmas angel theme, then perhaps you should tell our human friends that the only true Christmas angel is present here tonight."

The Archangel was red around the nose and turned his head away from his brother and the humans, because he knew what Cas was alluding.

And it seemed to make "click" in Sam's and Kevin's heads, because they gave Gabriel a wide grin, as they looked at him and the Angel quietly murmured something in Enochian to himself.

"I think Castiel is right Gabe. It is time that the only true Christmas angel shows himself to us."

Oh great, even Sam was no longer on his side and he threw an evil look into his direction, before Gabriel's golden eyes turned to Kevin.

The young prophet shuddered and stopped laughing, when he saw the scowl the Archangel gave him and he knew he should better keep his mouth shut now, or it would end badly for him. He knew Gabriel now long enough to know that he would pay him back almost everything. Sam on the other hand seemed to have no fear of revenge, because he grinned merrily and even waggled his eyebrows, as the golden eyes fixed him again. Even Charlie began to laugh, as it dawned in her head as well; only Dean still looked confused.

Had he learned a little more about Christianity, he would now grin like a Cheshire cat as well.

"What's so funny?" he asked and his brother pulled him quickly to his side and whispered the answer into his ear and only a split second later Dean was grinning broadly at the Archangel among them.

Now Gabriel had no one who was on his side anymore and the embarrassment in him grew with every second.

His brother and his friends were right, because he was secretly the true Christmas angel, because he had been the angel who had announced the birth of Jesus; the reason why Christmas was celebrated and his friends, and especially his little brother, knew about that (and of course the rest of heaven knew it as well).

"Are you guys serious?" the Archangel grumbled, who was now as red as a tomato.

"Of course we are, brother. You know what Gabriel? I shouldn't wear these clothes, you should wear them."

"Pfft, please Castiel. They look so much better on you than on me. It flatters your dark hair."

"Stop stalling Gabe!" Sam grinned and the angel gave him a murderous look.

"I am not stalling Samantha!"

"Oh yes you do," it came from Dean and his grin was going to split his face in two.

Eventually Gabriel gave up and he threw his hands up in resignation.

"Okay, okay fine. You won. You're right," he grumbled.

Oh, how he hated losing to humans!

"With what we are right?"

"Kevin!" Gabriel growled.

The prophet was just asking for revenge!

"Answer his question!"

Oh great, Cas also!

Apparently the whole world, including heaven, was now against him.

"Well, fine you sadists! I am the one who appeared Maria and proclaimed her the birth of Jesus Christ. And since then I am called the Christmas angel by many people. Are you satisfied now?"

"Very satisfied," Dean grinned and the others agreed with him by nodding their heads.

But he also recognized something like awe in their eyes and Gabriel felt a wave of pride rushing through his body. He was, after all, not some ordinary angel standing here in front of them and with whom they could fool around. He was one of the best known and most powerful angels of heaven.

Castiel stepped to his side and pulled him out of his thoughts and Gabriel frowned as his little brother gave him a grin.

"I also remember very well the day when Jesus was born. All the angels of heaven sang a song for him. Do you remember it brother? Together with Michael and Raphael you've led the heavenly choir."

"How could I forget that..." Gabriel murmured and a gentle smile graced his lips as he remembered what was almost forgotten by so many angels and humans alike.

But his smile faded quickly when he heard his friends shouting "Sing, sing, sing!" over and over again and again there was this sense of shame in him. It was so long ago that he had sung and he didn't even know if he still could. And so far, a human had never had the honor to listen of the voice of an angel of his rank for such a long, long time.

He could look at it from all sides, but he could no longer deny it: Gabriel was nervous.

"Oh come on guys, why do you want to hear me sing?"

"Are you serious Gabe? When will we ever get the chance to hear the Christmas angel sing?"

Dean would probably never stop calling him "Christmas Angel" ever again...

"C'mon Gabe, sing for us."

Of course Charlie had to join him as well.

"Please~."

And Kevin also and when he looked at Sam and saw how he already opened his mouth to say something, he just had to roll his eyes at them.

When a hand was placed on his shoulder, he winced slightly and when he turned his head, he looked into the bright blue eyes of his little brother, who smiled at him so meek that Gabriel forgot all his worries in no time.

"I would also love to hear the voice of my big brother. Please Gabriel. For old times' sake..."

"Cas is right. After all, it is Christmas."

How right Sam was.

What would Christmas be without angels and beautiful music?

"All right, all right. Fine. I sing. But…"

Gabriel grinned and he grabbed his little brother by the arm and pulled him back to his side, because the younger angel had already been on the way back to the sofa.

"...I won't sing alone!"

Castiel could feel nervousness in his body and he began to tremble slightly.

Even his wings quivered under his growing nervousness.

It was so long ago that he had sung and like his brother Gabriel he was afraid that he couldn't sing anymore.

But then he looked at the expectant faces of his friends and all his nervousness fell away from him, like the leaves of an autumn tree.

It was Christmas and they should have fun.

He turned to Gabriel and gave him a big smile.

"I would love to sing with you brother. Which song do you want to sing?"

Gabriel grinned, leaned toward him and whispered the choice of his Christmas song into his ear which made Castiel grin also.

"The songs in the language of the angels would probably be too much for you, that's why we opted for a song you humans like to sing on Christmas. Just lean back and enjoy the show."

He didn't need to tell Charlie, Kevin, Sam and Dean twice and so they made themselves comfortable on the big sofa, snuggled up in their blankets and looked expectantly at the two angels, who now stood in the middle of the room and cleared their throats.

And then they sang:

"Hark! The Herald Angels Sing. Glory to the newborn King. Peace on earth and mercy mil. God and sinners reconcile..."

The voices of the two angels were like balm for the soul of every human being.

Gabriel's voice was deep and majestic, and he sang each verse in a gorgeous deep tenor and each of the four humans got goosebumps.

Castiel's voice was just as nice as the Archangels.

Although he didn't sing in a tenor, but his voice was also deep and just perfect for this song and the four friends swore that they would be able to hear the true voices of the angels in this very moment...

When Gabriel and Castiel had finished the song, loud applause and cheers of their friends echoed through the room and both Angels blushed deeply; yet they smiled and they spread their wings out proudly, because even Gabriel had made his wings visible during the singing.

For almost an eternity Castiel had no longer heard his brother sing and he felt that Gabriel had enjoyed every single moment of it as well. He had his eyes kept close and had let himself fall into the song.

There was no Trickster anymore; only the mighty Archangel who he used to be back then. And Castiel had enjoyed it to sing again, especially with his big brother by his side.

There was nothing better in this world for him right now.

"Wow! That was simply amazing!"

Charlie's words made the two angels laugh and blush even deeper and they gave the young woman a grateful smile and it was not long before the others also made a compliment after another and they could even persuade Gabriel and Castiel to sing another song for them.

This time they had chosen "Silent Night".

One of the most popular Christmas songs ever…

The four humans listened silently and spellbound, listened to the wonderful voices of the two angels and slowly their eyelids became heavier and when Gabriel and Castiel had ended, their friends were cuddled up on the sofa and had fallen asleep.

Castiel and Gabriel looked at each other with a smile and seemed to think the same thing.

Quiet and anxious to awaken any of them, they crept to the sofa and took one of the humans on their arms.

Gabriel lifted Charlie on his arms and carried her to her room, where he laid her gently into her bed, covered her body with the warm blanket and gave her a gentle kiss on the forehead, which made the young woman smile in her sleep.

"Merry Christmas my little one..." Gabriel whispered softly into her ear, before he turned around with a smile on his own face and went back into the living area, where he already met Castiel who had Kevin on his arms to bring him to his room.

Sam and Dean followed shortly afterwards and the bunker became quiet again.

As the humans slumbered peacefully in their beds, Castiel and Gabriel sat down on the sofa and looked silently at the huge Christmas tree, which stood not far away from them in the corner of the room and each of the two was caught in his own thoughts.

Castiel scooted closer to his brother, leaned against his side and closed his eyes when his brother tenderly stroked his fingers through his hair, folded his wings protectively around him and leaned his head against Castiel's and listened to the silence.

"Merry Christmas Gabriel," Castiel whispered quietly and with a gentle smile on his lips, which the Archangel answered with a soft kiss on his forehead.

"Merry Christmas little brother…"

And in that night the spirit of Christmas was stronger than ever…

The End
