Chapter 10

The building began to shake again. Debree began to fall from the ceiling. The four of them could see the large cloud of black smoke building up outside a window.

"They're going to tear down the building!" yelled Sam.

Alexandria looked at Castiel. The two stared at each other for a long moment. Sam wasn't sure be he thought it looked like the two were reading each others mind. Castiel opened his mouth to speak to Alexandria. With sorrow in his eyes he only said, "Thank you" and with that, Alexandria turned towards Sam and Dean. Dean wondered what had just happened between the two angels.

"Dean, Sam! I need you to disrupt one of the sigils. Once it's done, Castiel will get you out!" said the Angel.

Castiel's face grew with protest.
"I'm not going to leave you! You can't kill them all yourself!" he yelled.

Sam and Dean didn't know what to say. They knew that when Angels, Gods, and even humans were arguing, it's best to stay back and stay quiet.

Another loud rumble echoed through the room. Suddenly, part of one of the walls had old paint chip off of it, which caused one of the sigils to be ineffective. The four of them realized what happened and suddenly demons left and right made their way into the room. It wasn't what Dean and Sam were used to. it wasn't demons possessing people. It was the true forms of the demon army. Sam and Dean could barely see past the smoke created by the demons.

"Sam! Dean! Lookout!" yelled Castiel.

Dean and Sam felt something grab them from behind. Some demons started to make their attack when the hunters suddenly were pushed to the ground. Alexandria saved the Winchesters from the demon's attack.

"Cas, do it now!" Alexandria commanded.

Dean heard a voice in his mind. he was startled at first until he comprehended who it was and what the voice was saying.
"Close your eyes." said the voice who belonged to Alexandria in his mind. With no hesitation, he shielded his eyes, as did Sam, from what was about to happen.

Castiel stood a firm stance in the middle of the room. His eyes full of protectance for his family. He held his hands out and white light shone from his vessel. After a few moments of dark screams, the light faded away. Castiel's image slumped slightly. He had used nearly all his energy for his attack. Dean and Sam stood up and looked to the angel.

"Cas, you okay?" asked Dean.

"I'm just drained." he replied half-heartedly.

Sam looked around the room and to all the burn marks from the demons killed in the angel's attack.

"Cas, did you kill them all?" he asked in amazement.

"No. That was the first attack. Only 1,000 or so. The rest of the army will attack soon." he replied as he started to fall. Dean caught Castiel before he hit the ground. Sam and Dean looked at each other in a worried way. They soon turned to Alexandria who started to walk to the middle of the room.

Soon after, the ground started to quake more fiercely than it had before. The four of them waited for the next set of demons to come. Smoke gathered outside the building. The four looked around at the smoke, ready for it to attack them. A dark, deep voice, one neither the brothers or angels had heard before, came from the demon army.

"Alexandria" said the deep voice filled with pure evil.

The three men looked at Alexandria. She returned the look to them and gave a slight nod. She turned back to the smoke with anger building up.

"Come and get me." she said with anger.
She was tired of being chased. Tired of being controlled. She wanted to end this now and send the rest of Hell and Crowley a message to fear her and fear the hosts of heaven as they once had.

"Cas! Cover them!" she warned.

The angel forced the men to their knees and covered the hunters. The brothers thought, at first, they felt more than Castiel's arms covering their backs.
"It can't be wings, could it?" said wondered.
The brothers already knew what to do, and they shielded their eyes from the angels grace that was about to come. The black smoke started to fill the room to attack the four of them. Castiel lifted his head to witness his creation at her fullest power.

Alexandria held her arms up to her sides as Castiel had done just before. Soon, a pure white light shone from her palms. It didn't stop there, however. the archangel started to shine from her core. Soon her vessel began to fill with the purest white light imaginable showing her wings on the wall behind her. A huge, long, and slightly burning white light filled the whole room. Dean and Sam could hear the violent screams come from the army, then silence. The light had faded. When Sam and Dean felt Castiel leave their side, they stood up to see the room completely destroyed. Their eyes couldn't seem to leave the sight. Sam finally let his gaze drift to Castiel, who was knelt down next to Alexandria who was unconscious.

"Dean!" yelled Sam getting his brothers attention to the unconscious angel.

They both ran to Castiel's side who was worried for his daughter.

"What happened?" asked Dean.

"She used all her energy. She'll come around in time, I'm sure." replied the worried angel.

The three men looked around the room again. They truly were amazed by the power Alexandria had. With-in an instant, the four of them were back at the motel room in Tremont.

Sam and Dean were standing near the door. They walked towards where the beds were and noticed Castiel sitting on the bed holding onto Alexandria, who was still unconscious.

"Cas, again, give us a warning." said Dean.

"My apologies." replied the Angel.

"You weren't kidding when you said unstoppable, Cas. She's a badass." said Dean with a slight smile trying to lighten the mood.

Castiel never left his gaze to Alexandria. Instead, he just nodded to the statement made by Dean.

"There was a moment, I swore I heard her talking to me in my head." Dean chuckled.

"You did." Castiel said bluntly.

Dean's smile was wiped away. He wasn't sure if he had heard Castiel correctly.

"I did?" he asked.

Castiel gave a nod.
"To answer your question from earlier, she has parts of two souls in her, created as one, of course. One of those souls belongs to you, Dean."

Dean's eyes widen. he wasn't sure how to feel. Castiel stole a part of his soul for his creation. He felt like for that, he should be mad at the angel. Yet, he had a part of him that defined the amazing angel, and he felt honored.

"Ah." was all Dean was able to mutter out at first. "Well, whose the other one?" he finally asked.

Castiel slowly turned his gaze to the younger hunter.

"I... I heard her voice too." Sam said towards Dean.

"You two have the strongest souls that I know of." Castiel stated.

He could see slight anger in Dean's eyes. The older hunter wasn't too thrilled about Castiel stealing his soul. Castiel's gaze toward the brothers moved back to Alexandria. He wasn't sure what to think. he knew she'd be okay, he just didn't know when. He reflected to what she had said right before the first attack from Hell's Army.

"Castiel" she said.

Castiel's attention was sent to her. The two continued to speak to each other telepathically.

"I remember. I remember, everything." she continued.

"I'm so sorry." he replied with sorrow built in his features.

"It's okay, father, I forgive you." she replied with a smile on her face.

Castiel's expression went from guilty to relieved. He smiled back to Alexandria and nodded.

"Thank you." he whispered out loud.

Sam and Dean watched Castiel from the other room. They couldn't help but be amazed by the way Castiel seemed towards Alexandria. They had always thought that Castiel, and all angels for that matter, were emotionless. they knew now, that they were wrong. Any anger the brothers had towards their friend turned to sorrow.

"I still can't believe he did that." said Dean. he sounded more shocked than he did annoyed or angry.

"I think it's kind of neat. She is the strongest thing we know of, and we are part of the reason." Sam said to Dean. To sam, he felt like his family, who used to just be Dean and Castiel grew by one more.

"Yeah, me too, but don't you feel just a little upset?" Dean asked in return.

"How can I?" replied Sam. "Look at him, Dean."

The two hunters stared back towards Castiel, who was still holding Alexandria as if he was guarding her. he was mumbling a song to her in Enochian.

"He really does care for her. Call me crazy, but to me, he is already doing more to help her than Dad ever did for us." said Sam.

Dean wanted to protest, but he couldn't. he knew, deep down, that Sam was right. The looks he saw his friend give when Alexandria was taken were the same Dean himself made when Sam would be taken. Dean knew he would go to the end of the world to help his brother. he knew that Castiel would die for his daughter just as Dean would for Sam.

"You're right." Dean finally said.

With that being laid out, Dean got up from the table in the other room and walked towards Castiel. He had just ended the song he whispered to Alexandria.

"Hey Cas, how's she doing?" Dean asked with sincerity in his voice.

The angel looked up to Dean and replied,
"I think she will be okay."

"What were you singing to her?" asked Sam who had entered the room to join the others.

"It's an old Enochian hymn. It's used to heal the ones we love. I've used it quite a bit more since I've met you two." he replied.

The three sat in silence for a few minutes.

Finally, Castiel stood up as he let Alexandria lie on the bed.

"I want to apologize. I should have never stole parts of your souls without your permission." Castiel said.

"We're okay with it. We actually think it's nice, being part of her charge." said Sam.

Castiel nodded at the hunters with a smile.

"Besides, this makes us Uncles, in a cool, strange way." joked Dean.

Sam and Castiel gave a small chuckle to the comment before being interrupted by a slight groan. The three looked towards the bed. Alexandria slowly opened her eyes and sat up to the edge of the bed.

"It's been a while since I've used that much power." she groaned out.

"Are you okay?" asked Sam.

The three men stood by the bed as she started to stand up.

"I'm started to feel better, thanks." she replied. "Did we at least win the fight?" she finally asked.

Dean gave a big smile towards Alexandria.
"You and Cas kicked their ass!" he replied.

Alexandria chuckled a bit to the statement. She looked towards Castiel who looked at her in relief. He was glad to see her up and moving.

"We make a pretty good team. We did in Heaven and we do here." she said to Castiel.

"You don't seem too different." said Sam. "I mean, most angels are humorless or don't show much emotion."

Alexandria looked at Sam with a grin.

"It's my soul, making me half human. So I guess it's my human traits." she explained.

The four of them stood in silence looking at each other.

"So what now?" asked Dean.

Alexandria looked to the brothers and shrugged.
"I don't know. I'll just go where ever fate takes me." she replied.

"Where ever you go, I'll be with you." Castiel said with a smile.

Sam and Dean knew how valuable the angels could be to them. They needed all the help they could get for the challenges they would be facing.

"You know, you both are welcome to come with us." said Sam.

"We could use your help, and your badassery." said Dean amused by his choice of words.

The angels looked at each other for a second thinking about the offer. Finally they gave each other a smile and turned to the brothers.

"I guess I could give hunting a try." said Alexandria with a smirk.

The four gave each other a smile. Finally Dean started to grab his things.

"I say we get out of this town then." he said.

All agreed to his suggestion and headed for the Impala. The two angels were ahead of Sam and Dean. Sam looked over to Dean who had a big grin on his face.

"What is it?" asked Sam.

"It's just, we're back. We have a team again." said Dean. "It's Team Freewill back in action." he finished.

Sam looked to the angels, then back to Dean and smiled. The two hunters made their way to the Impala where the angels waited.

"Can I ride shot gun this time? Castiel asked with hope in his voice.

"No." said the brothers in unison.

Castiel gave a slight look of disappointment to the brothers.

"It's okay, I tried earlier." said Alexandria.

Dean gave a small smirk to himself when he heard Alexandria say that.

The four got in the car, and the new Team Freewill made its way to the next city, ready to take on whatever fate had in stored for them.

El Fin... maybe.
