Chapter 4: Guardian Angel

Hours.

I've been trying to sleep for hours but sleep never came. I guess I was still running on adrenaline after the whole ghost incident. It's happened before on other cases. Sleep never came easily for me because I was still on high alert. So it was safe to assume that was the reason why. Plus the motel bed I was sharing with Dean wasn't exactly comfortable. Seriously it felt like there was rocks underneath me.

Whenever I was with the boys I always ended up sharing a bed with Dean. I didn't share with Sam because of how huge he was. Besides he always took all the blankets. Not that he wasn't great to cuddle with, cause he was. I just needed my share of blankets too.

Just as I was about to finally drift into sleep, I heard the door close making me lift my head from the pillows. Thanks to that noise, the sleep I ha went away.

Damn it.

When I looked around my surrounding I noticed that Sam wasn't in the room. Huh...that's weird.

Did he leave to get a snack or something?

I laid my head back down again on the pillow, and tried again, for like the hundredth time, to get some sleep. But why, oh why, was this so hard to accomplish? Curse you insomnia.

Dean, as if sensing my troubles turned next to me and instinctively put his arms around me. I welcomed his touch and snuggled closer to him. At least I had a cuddle buddy with me. I wasn't alone.

It was then that I felt Dean tense up in his sleep. His arms becoming tighter on me as if he thought I was going to go away. I looked at his face and noticed it was scrunched up as if he were in pain. He was probably having another nightmare. Poor Dean. Can't he catch a break? Sleep is supposed to be an escape for him. The place were he can just relax and not worry about all the problems he has or will face in the future.

I heard him release a small gasp and saw his eyes as they shot wide open. I wanted to ask him if he was alright, but even I knew that was a stupid question. Of course he wasn't, who would be? So instead of talking I just began rubbing his back in comfort. I think Dean appreciate this since he gave into my touch. After a few minutes of me comforting him, he finally spoke up. "Thanks, Ava." He said softly.

I nodded my head ready to thank him when all of a sudden a voice interrupted me.

"Hello, Dean." Castiel said all of a sudden, I saw how he was just sitting on the edge of the bed. What was he doing here? Not to mention when did he get here? He then looked at me giving me a nod. "Ava."

I just gave him a awkward wave. "Umm, hello..."

Dean let out a frustrated sigh, obviously not liking that he was here.

"What were you dreaming about?" Castiel asked Dean with full on curiosity in his voice.

Oh not the question to be asking him right now...

Dean just gave him a glare as he started to take off the blankets. "You get your freak on by watching other people sleep? You just can't spy on people. Especially not on females." He said pointing his finger at me. "Not what do you want?" Dean asked Castiel while I was just looking away avoiding his gaze on me. Yet again. But I could still feel his eyes on me.

Castiel's face and voice then became serious. "Listen to me, you have to stop it."

Dean looked confused just as I was. "Stop what?" He asked him.

Instead of just answering him, Castiel put two of his finger's on Deans forehead making him instantly disappear.

"What the?! What did you do to him?" I asked Castiel panicking over Dean. I mean, he was there and then the next second he was gone...

"He's alright. You have no need to worry. I sent him somewhere." Castiel answered me, his voice calming me down.

I just took a deep breath and nodded my head. "Where did you send him?"

"1973, I sent him there for him to find out the truth." He responded back to me.

I gave him a confused look. "The truth?" What truth was he talking about? Maybe Dean needed my help. With that thought in mind I looked into Castiel's blue eyes with a determined look as I crossed my arms. "Well whatever this truth is, send me there with him so I can help."

He just shook his head. "No, this is something he needs to do on his own. My orders were to send him and only him."

I was even more confused now. "What orders?" I asked him but he completely stayed silent. I was beginning to get mad, so I asked again with a raised voice. "Castiel, what orders are you talking about?"

He looked startled for a second. I think it was because I said his full name, I hadn't said it out loud before. For some reason though saying out loud sent an unknown feeling go through me.

He composed himself before answering me. "Orders from heaven."

"So your orders were to send Dean but not me?" I asked him and he nodded his head at me.

"Well then what do I do? I have to help somehow, I just can't stay here." I said to him as I got up from the bed ready to leave the room.

Castiel instantly came to my side. "You can not leave this room. My orders were to send Dean but they were also to make sure you are kept safe."

I gave him a look. "Keep me safe? From what? Look buddy I need to find out a way to help Dean and if your not helping then I'll find someone else who will."

Just as I was about to open the door he suddenly was standing in front of it. "Keep you safe from anything that can harm you. Ava, you cannot leave this room." He then looked into my brown eyes with his own blue eyes with a pleading look. "Trust me."

I stared at him for a few minutes.

Can I trust him? Well he was an angel after all. I sighed, hoping I'm making the right decision...

I reluctantly nodded my head. "Alright, I won't leave this room until Dean comes back."

"You swear?" He asked me with narrowed eyes.

"Yes, I swear okay?" I told him as I moved back to sit on the bed.

He took a seat next me." I must leave for a little bit. I have to inform Dean you are safe. I trust you will not leave?"

"Alright." He just looked at me as if waiting for me to answer his question, I rolled my eyes. "I won't leave. I swore remember? Trust me." I said using his words on him.

He merely gave me a quick look before I heard the sounds of wings and saw him disappear.

As soon as he was gone I laid down on the bed.

"Why is he so bent on making sure I'm safe?" I asked out loud. Why does he care so much?

Dean was following his younger father carefully trying not to be detected by him. Why in the world would Castiel send him to 1973? It made no sense to him what so ever.

He was confused, not to mention pissed off as well.

Turning around the corner he almost ran into said angel.

Dean then gave him a fuming look. "What is this?"

"What does it look like?" Castiel said non affected by the way Dean was talking to him.

"Is it real?" Dean asked him.

Castiel just simply answered him. "Very."

Dean let out a deep breath trying to control his temper. "Okay so what? Angels got their hands on some Delorean? How did I get here?"

Castiel gave him a confused look not understanding that saying before answering him. "Time is fluid, Dean. It's not easy but we can bend it on occasion."

"Well bend it back. I gotta get back to the motel I left Ava. I gotta make sure she's alright." Dean was worrying over her, even though she was a hunter. To him she was still that young girl who was afraid of the dark that would constantly hold on to his hand for support. He was always there to protect her just like Sam and Bobby.

Castiel gave Dean a serious look. "Do not worry for Ava, I'll make sure she's kept safe. It's my duty."

Dean furrowed his eyebrows. "What do you mean it's your duty?"

Casitel sighed he really didn't want to tell Dean who he was to Ava. At least not yet, he hadn't even told her. He would wait after Dean finished with his task and then he would tell him.

"That is not of import." He told him with a look that said 'end of discussion'.

Dean did not like this one bit. What did he mean it was his duty? Except he knew not to piss this guy off otherwise he'll be stuck here forever. Better do as he says, that way I can go back home. He thought to himself.

"Fine then tell me what the hell I'm doing here."

"I told you, you have to stop it." Castiel repeated what he had said to him before.

Dean just sighed and was full on agitated at the angel now. "Stop what? huh?" He really had to idea what he was talking about. "What is there something nasty after my dad?"

The sound of cars honking made Dean look away from Castiel before turning back to him only to notice he was gone.

"Come on! What are you allergic to straight answers, you son of a bitch?!" Dean yelled out loud. Damn angels.

I closed my eyes when Castiel left and felt how sleep was coming back to me.

Oh now you return. When I want to stay up huh? Isn't sleep wonderful. Note my sarcasm.

I wonder what Dean was doing right now? Was he safe? God, I hope he was. Castiel said he would be fine. For some reason I believed him there was something about him that made trust come easily. I mean, don't get me wrong I was still wary about him. He just made it seem alright to trust him.

Whatever that meant. Maybe the lack of sleep was finally catching up on me.

I then heard the sound of wings making me open my eyes.

Castiel was there standing in the middle of the room looking for me, once he found me he looked relived. "You stayed."

"Yup, I did." I said to him as I stood up from the bed and walked to were he was standing. "Trust remember?"

"Yes trust." He repeated back to me.

"Castiel, you gotta give me some answers man." I said taking a deep breath. "Why do you care so much for my safety?"

He looked taken back from my question. "Because Ava, it is important to keep you safe."

I sighed. "Okay, but why? What's so important about me?"

Castiel looked directly into my eyes. "Everything about you is important, Ava. Don't you see?"

"Castiel, I really don't understand." I said to him growing impatient. "Why must you protect me?"

"It is my duty to protect you." He stated with a determined voice. "God, ordered me to protect you because you have one of the rarest souls I have ever seen."

"You mean what you told me the other day, about my soul being bright?" I asked him. My soul was bright and now I find out it's a rare one as well?

"Yes, Ava you have a pure soul. It's very rare to find someone that actually has one. Whenever one exists they are often assigned an angel to guard them. For you I am that angel." He said softly to me.

I was left with my mouth wide open. He was my guardian angel? I have a pure soul? I was meant to be protected by him? Oh dear... The things you learn all in one day.

I tried finding my voice. "So...you're my guardian angel?"

He nodded his head. "Yes, I was bestowed with the gift of protecting you."

Wow. This is huge. An angel of the lord watching over me?

"That's...um...well...great." I said trying not to show my shock, although I think I failed.

"Do not worry little one, for I will make sure you are well from all danger." He stated back to me, his blue eyes filled with reassurance.

"Thanks." I merely nodded at him then thought of something. "Why are you suddenly protecting me now? Why not when I was younger?"

Castiel sighed. "There is a time and place for everything, Ava. I wasn't meant to be in your life when you were younger, but I am now."

"Wait! Is that why I'm able to hear you? Because of my pure soul?" I said remembering be able to hear his voice, while the other couldn't.

"Yes Ava, I believe that is why." He simply answered back to me. "You are one of those special people." I suddenly became overwhelmed, this was just so much to take in. I walked back to the bed to take a seat. Running my hand through my long brown hair.

"I know this is overwhelming news but know that I am here for you." He said gently. "I am your protector."

I gave him a small smile. "Okay, Cas." Maybe it was a good thing that I had an angel guarding me. Right? I mean everyone in there life has at least once thought they had a guardian angel watching over them.

He tilted his head to the side. "Cas?" He sounded confused.

"Yeah, I figured since your names pretty long that I could give you a nickname instead." I told him with a giggle.

"This is term of endearment correct?" I nodded my head. "Alright you can call me Cas. I see this as a form of bonding as well."

I smiled back at him and Cas suddenly became serious. "I must go bring back Dean. I'll return shortly."

"Alright." I told him and started at the spot where he once stood.

A few minutes later I was sitting on the bed waiting for Cas and Dean to return.

I then heard a gasp from the other side of the bed and noticed Dean was laying there again. I instantly rushed to his side.

"Dean!" I said out loud, glad that he was back.

He brought me into a hug.

"Dean are you okay? What happened?" I asked him.

He just continued to hug me. "I couldn't stop it." He murmured into my neck. "Any of it, she still made the deal."

"Your mom?" I asked carefully not to make him even more sad.

He nodded his head.

Dean then ended the hug and we both looked up to see Cas standing at the other side of the room.

"She still died in the nursery, didn't she?" Dean asked him.

"Don't be so hard on yourself. You couldn't have stopped it." He answered him.

"What?" Dean replied shocked by what he told him.

"Destiny can't be changed Dean." Cas said as he turned to face him. "All roads lead to the same destination."

Dean gave him a look. "Why did you send me back then?"

"For the truth." He simply said to him. "Now you know everything we do."

Dean now was angry. "What the hell are you talking about?"

Cas then moved his gaze towards the other bed. Sam's bed... What did Sammy have to do with any of this?

"Sammy?" I said out loud.

Dean then gave the angel a glare. "Where's Sam?"

"We know what Azazel did to your brother, what we don't know is why-what his endgame is. He went to great lengths to cover that up." Cas finished telling us.

Dean not liking what Cas was saying just gave him another glare. "Where's Sam?"

"425 Waterman." Cas simply told him.

What was Sammy doing there? Is that why he left in the middle of the night for? Oh Sammy I hope you are alright...

"Ava come on were leaving." He told me as he took my hand bringing me to stand next to him as he was packing everything.

Castiel's voice then all of sudden became rougher, startling me for a bit. "Your brother is headed down a dangerous road Dean. And we're not sure where it leads." Dean then grabbed a gun, just as he was putting on his leather jacket. Cas then turned to face us. "So stop it, or we will."

What? What did he mean we will? Are they gonna hurt Sammy?

Dean stopped his movements and stared at the angel in complete anger and shock.

Cas then looked ready to leave before he called our attention to him again. "One more thing, as I have told Ava earlier, I am here to protect her. No harm shall come to her." He narrowed his eyes at Dean, while his voice became deadly serious. "So if either you or your brother bring her into harms way I will take drastic measures in order to keep her safe. Am I making myself clear?"

"I wouldn't let anything happen to her nor would Sam." Dean snarled at him.

Cas gave him a glare in return. "With how things are going I'm not so sure about that anymore."

Before Dean could reply back to him Cas had disappeared.

Dean looked back at me with a firm look. "You know I wouldn't let anything happen to you Ava, neither would Sam."

"I know, Dean. Cas is just worried for my safety. He is suppose to protect me after all." I said trying to calm him down.

He nodded his before giving me a look. "Cas?"

I sheepishly looked onto the floor. "Umm yeah I kind of figured Cas would be better, since Castiel is to long of a name."

Dean sighed and ran his hand through his hair. "Ava, I don't want you getting close to him. We barely know the guy."

I was about to answer back before he interrupted me. "No Ava I know how you are. One of your biggest faults is that you trust to easily." I looked away. He was right, I trusted people to easily sometimes. My compassion was a gift yet at times it made me the weakest link out of my family. There was just something about the trench coat wearing angel that gave me a sense of comfort.

Dean grabbed my chin softly making me look at him again. "Hey, I'm just trying to look out for you kiddo."

I nodded and brought him into a hug. "I know Dean, I know."

He gave me a squeeze and kissed my forehead as he ended the hug.

"Come on we gotta go find, Sam." He told me before we left the motel room.

I just hoped Sam was okay...
