After some time had passed in heaven, I found myself forgetting about my life so much that I couldn't remember the little things like my name. When I asked Anna if she remembered my name she told me that everyone forgets in heaven and that I should welcome it. It would be easier for me if I forget.

Anna always called me Castiel. I don't remember if that was my name or not but for some reason she always called me Castiel and when I asked her why she told me it suited me because it means changes and journey, again she spoke in riddles I didn't understand.

I found myself forgetting my family and Michael but I desperately tried to hang on to the memories I still had of them.

Time flew by and I was still learning all the rules of heaven and I quickly found out that heaven was a lot more complex than I thought it would be. There were so many different types of angels and all of them had different duties.

One day my garrison received an order and I found myself on earth again. Anna and our garrison had been sent to earth to watch over the humans. Our job was to follow them as they went about their lives and keep them safe and away from sin. However, some of us became damned in the process and began to question our faith.

"I do not understand. Why does our Father give these humans emotions and makes us cold as statues? Does our Father not love us as He loves humans?" Anna asked with her back to Castiel.

"Anna, you must have faith. Some of our brothers and sisters are beginning to question whether what we are doing on earth is pertinent. These humans are beautiful and our Father did create them, Anna."

"We are told that we must have faith and obedience. Do you know how many people have seen God? Actually seen our Father's face?"

"You don't because no one has. No one that we have ever spoken with has seen our Father. I question whether He is truly visible."

"Anna how can you say that? You must have faith."

"I want to feel again. Do you still remember what feelings were like? Don't you miss it?"

"Anna, you have to come and speak to our brothers and sisters with me. I can't keep them devoted without your help."

"Of course you don't miss it. You're still a very young angel. Give it some time and you too will begin to question."

"I will miss you Castiel," Anna told me as she walked away.

"What do you mean Anna? Where are you going?"

"To fall."

"You can't, Anna."

"Don't worry Castiel, I don't think this is the last you will see of me."

"What does that mean Anna? I don't understand."

"It means you shouldn't trust so easily. Angels lie Castiel, you should remember that."

"Castiel, ask yourself if God is real and He plans our destinies, then why is it that you where destined to be killed and become an angel? Not every human is made an angel. Then ask yourself why you were?"

All I could do was watch as Anna spread her wings and fell.

After Anna fell, I was made in charge of our garrison and I kept what Anna had told me in my mind. There were a lot of things that Anna told me that I didn't understand.

As the leader of my garrison now, I was to do what Anna had done for me when I had died. I was to explain to a new born angel what heaven was and why they were here.

When I reached the new member of my garrison, I found him still on the floor asleep so I crouched by his side to exam him.

The man suddenly awoke and flinched away from me as if he was frightened.

"It's okay Uriel, you're safe."

"Where am I?" the man demanded.

"In heaven," I answered.

"Where's my sister? I need to save my sister."

I didn't know what I could tell him to make him understand, so I tilted my head to the side in confusion trying to figure out what I could tell him so that he would understand.

I repeated what I had said. "You're in heaven" and that appear to work because he stopped asking about his sister and realized he had passed away and was now in heaven.

"I am an Angel of the Lord and my name is Castiel."

"What am I doing here?" he asked.

"You have been chosen to become a warrior of God."

"A warrior of God?"

"You have been chosen to become an Angel. You will become a part of our garrison."

"What do you mean a part of our garrison? And who's we?"

"You are born on the day of Thursday. Therefore, you are to become one of the angels that belong to the garrison of Thursdays."

"Why?"

"Because you were born on a Thursday and all angels born on Thursdays become a part of our garrison."

"Born?"

"You were reborn as an angel on Thursday."

"You mean I died on a Thursday?"

"Yes."

"Will I ever see my sister again?"

"No," I told him and I didn't miss the sadness in his eyes which reminded me of my own family.

"Don't forget about your sister and keep the good memories and don't forget them," I told him and he looked at me confused but I knew that in time he would come to comprehend what I meant.

The next thing I did was introduce him to the rest of the garrison and Ezra who was second in command.

I then explained to him how every angel has different faces and how he would receive his wings and face once he had accomplished his first order. I had to admit I was interested to see what face he would get.

After a short time had passed, Uriel was ready to take his first step in becoming an angel and I accompanied him as Anna did for me.

He placed the soul inside a rabbit and I watched as the white light of his grace filled its essence and it was the most beautiful thing I had ever seen.

The bright light that filled heaven and could be seen and felt everywhere in heaven was gone and the two shadows of black wings were all that was left as a reminder.
