A/n: Sorry, I got a little delayed to update, I was out of town. But I am back with the next one.

Marloweee1856: I really appreciate that you like this.

blueeyedcowgirl: They are very few fics with angel OC, mostly making one of the Winchester or their sister- an angel. I thought of this as something different, one who learned all her tricks from Gabriel, he trickster himself.

Thanks for following the story and marking this as your favorites.I hope you like this one. Please leave a review too.

Prayer Of God

Chapter 4: Third Horsemen

It took me time to find out where Castiel was. Firstly I tried to track him down by his grace, which was a waste as he had hidden himself quite nicely from other angels. Then using his phone which I was unable to reach, the number which I got from Gabriel's, how he knew that I wasn't sure.

I found him by coincidence when I heard a nurse in Chalmette, Louisiana praying for a John Doe with dark hair, blue eyes and angelic looks who was in coma. She thought that he was too handsome to be wasted by a brain injury. I went to answer the prayer and found myself face to face with the one I was searching for.

After Gabriel's death even thinking about his name made me burst into tears, which I couldn't shed. All the memories that I had with him, the time we spent together kept playing in my mind again and again. It was my fault as I was the one who convinced him to fight Lucifer even though the cause was worth fighting for. It was survivor's guilt. I channeled that grief into anger, a want to get the revenge for my brother.

Gabriel's default plan was to tell Winchesters about the four horsemen's rings that could cage Lucifer back, the one he came back from. Even though this idea sounded great, it was quite an impossible feat. Winchesters had killed War and Famine to get the rings and I was sure they could take down Pestilence too but the big deal in all of this was Death. He was the enemy you couldn't defeat. Death always wins. No one could fight him or kill him.

But the boys had reached this far, maybe just maybe this might not be impossible for them. I tried to track down Winchesters and found out that they were protected from the Enochian sigils, which was the reason of their absence in my human sensing radar. I had more chance of finding Castiel than Winchesters. And I did.

I was waiting outside his room and listened as Castiel talked with Dean. Nurse Mandy Johnson had let me stay after I told her that the patient was my brother and just after a snap of my finger she allowed me.

"Dean wait… You said no to Michael. I owe you an apology," I heard Castiel's rough voice, and a frown formed on my face when he hissed on moving a little to adjust himself for the comfort. "You are not the burnt and broken shell of a man that I believed you to be." I giggled a little but refrained myself form cutting his conversation, and with a welcome he hung up the phone.

I sighed and then stood on the doorway. "You should use nice words to compliment someone, especially those who are close to us."

The way his head snapped to me and the alertness in his eyes made me smile. "Good Morning Castiel. Hope you had a nice sleep."

His wide eyes stared at me without blinking as if I was his hallucination.

"It's me don't worry. I am the one who raised you from the coma," I replied trying to mimic Castiel's voice even though I totally failed.

He frowned and his head tilting in confusion and he replied after a few seconds. "Thank you." He hesitated. "Was that my imitation?"

I wanted to hit myself for trying to joke around with Castiel who didn't even get the humor in this. "You're welcome and yeah but it was a fail." He nodded.

I turned my head when I felt other Nurse coming to the room. She stopped when she saw me. "Sorry," she apologized and took a step back, "I didn't mean to interrupt."

I waved my hand. "No worries," and moved forward. "I am Sera Williams, Castiel's younger sister." I gave her a smile which she returned and shook her hand. She moved to towards the bed and took the chart.

"Miss Williams, your brother was in coma but he'd doing well now, really well. Doctors were surprised to see him wake up actually. The doctor on-call should be in to see you soon, and he can tell you further details," I exchanged a brief look with Castiel whose eyes were full of questions. "But I need some information. Basic paperwork."

I nodded."Of course but can you give us a few minutes. I would like to have a talk with him, its emergency." She looked reluctant but left us alone.

"You have been down for weeks. You almost seem human to me when I came here first time," I remarked and he seemed a little panicked. "Don't worry your sigils work. It was a lucky shot."

I waited for him to speak but he remained silent and then it became uncomfortable, so I broke it."Okay then, now if you are ready we could leave," I turned to him and watched as his eyes widened when he saw me coming closer. My hands touched his forehead and closed my eyes, humming as the warmth from inside me flowed to him and all the scars and pain left him. The awe on his face made me smile, this was first someone had healed him.

"There now, we need to leave soon as we can. I am craving a pizza,"

With a snap, Castiel and I were standing outside a place called "Pizza House" at the outskirts of Louisiana. I smirked when I saw Castiel checking himself and seemed surprised when he found that he was wearing his normal attire – dark suit, a blue tie and his trench coat.

The restaurant was bust even though it was early and I looked for a free table which I found at the right corner. Castiel was struggling as people moved around him and it made me laugh. After passing the traffic, he slid into the seat in front of me and looked around the area with fondness watching almost everything.

A short, older woman with her dark hair pinned up in high bun came to our table and smiled. "All right folks! You decided."

"A medium veg-pizza with pepperoni, onions and extra cheese, a coffee and ah, a slice of apple pie and a scoop of vanilla ice cream," I ordered and turned to look at Castiel who looked confused.

"Eggs?" This was a pizza place and he ordered eggs even though he had no idea what to order. I chuckled lowly when his eyes narrowed in confusion when she asked the type.

He frowned and stared at her. "Which one is a better choice?" I shook my head when I saw the eyebrows of the waitress reaching the sky.

"Two scrambled eggs and bacon, and make that coffee two," I looked Castiel up and down and tusked." A chocolate mousse and two waters," I ordered on his behalf and waited for the woman to go away who gave Castiel an odd look before leaving.

"So what did you do make yourself powerless. I mean you are almost human now," I questioned as soon the woman was out of hearing zone.

I watched as he looked down the table and squinted under my gaze. "Angels were trying to kill us; I had to draw sigil on my chest."

I whistled on hearing his answer. I wasn't expecting that. "Castiel the daredevil, huh,"

I stopped my jaw from falling to the ground when his cheeks turned pink. "Wow!" I realized he was blushing from the compliment.

Our order came and I stopped a second to look at him. It was funny how he hesitated to pull the ketchup bottle and then gave it a sniff. He pulled away, his mouth twitching in concentration and poured some on his plate and then placed it a little closer to himself. He struggled with the fork but then I motioned towards mine, and then started on my own to show him how to do it. He tried and succeeded, a triumph expression on his face, and I nodded feeling a little bit proud of him.

Angels could taste each and every molecule in the food which made it uneatable to them but Gabriel taught me how to control the taste and now I was able to eat human food without any difficulty and savor all flavors in my mind.

"You might have heard Dean telling you about Lucifer's cage." I said when I saw he was done with the food and was starting on the desert.

"Do you think it will work?" he questioned, before putting a spoonful of mousse in his mouth.

I sighed and leaned a little closer. "I wanted to tell you about this, but its a total bust in my opinion. You need Death's ring which is quite impossible to obtain unless he gave it to you on his own, which has never happened before. I am not even sure if this whole thing is possible."

"If someone could to do this, then they can," Castiel stated, a little protective showing in his voice which made me chuckle.

"Maybe they can but it would be a lot tricky to get Lucifer inside that. I am sure he would know about this. One thing I know about Lucifer he prepares for the worst."

He hummed and then said. "The desert is nice."

I smirked and nodded. I knew he was the type to love chocolate.

"It's chocolate," I said and a thought came to my mind. "Dean loves it; you should tell him that you liked this when you meet him again."

Castiel nodded, his eyebrows crinkling in puzzlement. "He likes pie."

I looked down and chuckled lightly and then gasped dramatically. "Really, I like it too. But the thing is everyone likes chocolate. It's like drinking water and breathing air nowadays."

"Ok."

We were almost done when he asked. "Where's Gabriel?"

I froze on hearing it, feeling sadness and pain in my heart on thinking about my brother. "He's dead. Lucifer killed my brother."

I didn't meet his eyes but I could feel his gaze on me. "I'm sorry."

With a deep breath, I nodded and clapped my hands on thighs. "So where are the boys? Have they found Pestilence?"

"No - but Dean said they had located where he was."

"Excellent. where?"

"Davernport, Iowa."

"Well we know where to go from here, we gotta keep moving. I'm pretty sure the boys would be there soon," I replied and looked at the waiter and nodded.

On cue, she came holding a yellow slip and placed it on the table in front of Castiel."Here's your bill, ya'll, need anything else?"

Castiel gazed at her with his puppy blue eyes and shook his head. This made the woman flush, a pink hue spreading across her cheeks as Castiel continued looking at her. I cleared my throat which made Castiel look at me and I raised my eyebrows at him.

I stood up and pulled out a twenty and a ten dollar bill and sat it down on the table.

"Thanks."

I motioned for Castiel who stood up and followed after me outside the place. I looked both ways and started towards right which seemed little less crowded.

"Here goes nothing."

I turned when we reached the corner and placed a hand on Castiel's shoulder and zapped us to Davenport.

As soon as my feet touched the ground, I could feel him. The Pestilence. He was here. On looking sideways, I realized that Castiel felt that too as he started to move.

"This way."

Castiel seemed to know where he was going and I followed behind him, letting him lead.

He might have become human but there was some grace left in him, but not enough to make him immune to Pestilence as he cleared his throat. He had become human by the way he had gotten thirsty and hungry but not fully.

We rounded corner and I felt the hair on my back stand and realized as I gazed at the building. This was it.

There were bodies littered around and a grimace formed on Castiel's face. First I thought it was due to the death but then I realized he was becoming sick.

"I don't think you should go any further. He's making you sick," I said looking down the hallway, a frown forming in my face as I watched Castiel catch his breath.

"No. They are in there," I met his eyes which told me in uncertain terms. He was coming in.

Winchesters were there.

I sighed and nodded."Stay close."

As we advanced through the hallway, I could feel the demon that was present, and watched as it became difficult for Castiel as he swiped his forehead, he was sweating as if he had a fever.

I pulled out my blade, ready to fight against the demon and Pestilence. Castiel stumbled a few steps and looked a little miserable. I felt bad for him, he was an angel of God but now he was too weak to fight the spell. I helped him stand straighter. He was able to keep himself on his feet but was struggling.

We stopped in front of the doors, past which were Winchesters and Pestilence himself.

The wave was strong, it might have made me stumble too if I wasn't an archangel. My grace helped me burn away the effect of the horsemen's spell, who was made after me.

Pestilence was made after the human came in existence.

"He's here."

I nodded and turned to Castile who pulled out his blade from the coat and kicked the door, startling everyone, including me. He was standing on the doorway, coming in the view of everyone while I was still hidden by the wall. I moved and stood beside Castiel.

"Cas?"

I heard Dean calling him but he looked straight at the old man wearing glasses with an arrogant smile on his face. There was a demon inside the nurse who was standing above the Winchester. They were sprawled on the floor moaning and feeling the effect of the Pestilence.

"How did you get here?" Pestilence questioned, his face narrowing on watching Castiel and I standing upright.

"I zapped him," I answered with determination on my face. Pestilence frowned but laughed as Castiel made a choking sound and coughed out blood and fell on his knees. The blade in his hands clattered to the ground. Before I could move towards him to help and the nurse came and stood between us.

I looked at her and chuckled.

"Really, do you even know who I am, sweetheart?"

The demon looked damn scared knowing I was an angel but she didn't know who I was. I glanced at Castiel who was breathing loudly and when Pestilence taunted him. "Well, look at that."

I turned to demon and moved towards her. She stepped backwards but it wasn't enough as I placed my hand on her forehead and watched as her eyes and body shone with bright light and she fell down, dead.

"An occupied vessel, but powerless. How fascinating… " Pestilence turned to look at me and grimaced. "And an angel with power."

"Too bad right," I tusked and glared at him. "Pestilence - Lucifer's pet. I am your boss's sister."

He scowled and spat, "I am not his pet," and then smirked. "but it's too late. It doesn't matter. Earth's gonna be hell soon."

"Well you wouldn't be there to see it," I moved and punched him in the nose, Pestilence fell back on the table. I yanked his left hand, placed it on the table. As soon as I did, Castiel stood up and in a flash of movement sprang to his feet and cut off the ring finger brutally.

I released Pestilence who cried in pain and surprise."Ahh….Maybe just a speck of angel."

Dean and Sam stood up as soon as the ring was cut off. The spell was broken, they weren't ill anymore. Pestilence vanished with a smile on his face which irked me.

I sighed and turned and looked at other three.

"Never liked this one. He was the messiest of four." I remarked and looked at Dean who had the finger with ringer on his hand.

"That's …." I scrunched my nose in disgust as Dean narrowed his eyes at me.

"What is she doing here?" He asked, his question was directed at Castiel, not me.

"Well hello to you too. Deanna Winchester."

A/n: Pestilence is dead. Dean is angry. Next chapter will be about Death and planning. Oh and Crowley.
