Angel of music (Dean/Reader/Castiel) part 2

The last thing I remember was falling. It burned as my wings tried to hold me up out of reflex. I landed next to another angel, but she was not too friendly. She had immediately tried to kill me. I had never fought before, I didn't even have an angel blade. Somehow I got the blade and killed her. I just flew to wherever my wings could take me. I landed rather harshly in front of a big round door. I remembered some angels looking for Castiel, my long time friend. We haven't talked in a few centuries, but I figured he was the only one who could help me. It was a long shot, but maybe, just maybe, he was here. I would go door to door looking for him if I had to.

Now I have two really tall men pointing at me with guns. I had hardly ever left heaven before, I am still rather young, but I thought that people were nicer than this.
"Well, crap, I was wrong." The green eyed one said. My grip on my blade tightened, tears escaping my eyes. "Please, I need to find Castiel. Please." I looked to the ground letting tears fall from my face on to the ground.
"(Y/n)?" My head shoots up, looking at this man with light blue eyes. I tilt my head and look at him sideways. "Castiel?" His eyes lit up, a smile on his lips. "CAS!!" I quickly ran between the two men with and embraced him in a hug. I then proceeded to hide behind Castiel so I wouldn't get shot.
"Castiel, I know I am still kinda new to earth, but is this how people greet others? Because I don't think that it's very effective-"
"(Y/n), it's okay, they won't shoot you. How did you get here? Why are you covered in blood? And why in the world do you have an angel blade?" He takes me over to the couch and sits me down beside him. The two men joined us in the room, the green eyed one kept looking me over for some reason.
"I fell. I think we all fell. I don't really know why I fell, but do know I fell. I landed next to another angel and she tried to kill me! I didn't even know her! I- I had to kill her." I looked into Castiel's eyes, then looked at my blood stained hands, "I killed our sister. After that I flew anywhere my wings took me. I ended up here for some reason." I stood up and subconsciously stretched my wings, falling over because of the pain. Or, at least I would have if green-eyes didn't catch me.
"Woah, take it easy there. My name's Dean and this is Sam. We live here with Cas." He explains. He is certainly beautiful, and his voice was surprisingly deep.
"Wait," Sam says, " Why is it so weird that she has an angel blade? Don't all angels have one?"
"All of the warriors have one." Cas explains, "(Y/n) is not a warrior. She was never meant to fight, or even hold a blade. How she survived an attack from another angel is beyond me."
"Well then, what is she?" They are talking about me like I'm not there. I straighten up and push my shoulders back and spread my wings. They look torn and broken, but I hold my head high.
"I am a herald, a messenger of God." I put my wings down, slumping and this time Cas catches me before Dean could. "Or, to be more specific, I am in the choir of angels."
"What?" Both Sam and Dean stare at me with confused, and rather humorous faces.
"I am an angel of music." I smile contently at them. Wow, I feel weak. The adrenaline is wearing off and I definitely flew farther than I should have. My eyes close of their own accord and I see nothing but black for a while.
