Daughter of Castiel (Supernatural/PJO Crossover

1-Doggos

*Grace's P.O.V*

I stayed on high alert, trying to focus on my surroundings. I was deep into a forest where apparently a lot of weird shit had happened, and it had been hours since we entered. It was a case I was working with Sam and Dean Winchester. The three of us were in a tight circle, watching each other's backs. We where heavily armed from head to toe with pretty much every monster killing weapon available.

I was growing increasingly agitated. There was a pit in my stomach, like when something bad was about to go down, but it had been there since we came in here, so my brain was telling me to chalk it up to my anxiety.

Dean let out a sigh, face scrunching into an expression of frustration. "We've been here forever, and haven't found anything!"

Sam stopped walking, and blew a strand of brown hair out of his face. "Maybe we haven't been looking in the right places."

I ran my fingers through my thick, black hair, resting my hand just before my undercut. "Maybe we need something to draw whatever is in here out." I turned to Dean. "Start singing AC/DC."

He chuckled, and rolled his green eyes. "Whatever kiddo. Why don't you play that weird noise you like?"

I stuck my tongue out, putting my hands on my hips. "Excuse you, Ava Max is a goddess, who I would gladly swear loyalty to."

Sam sighed at our antics. He looked like a dad who's kids wouldn't stop bother each other. "Cut it out you two. We need to focus."

"Grace is a monster magnet, maybe we could use her as bait." Dean wouldn't make the suggestion to us just anyone as bait, especially a sixteen year old, but he'd seen me single handily take down an army of demons, and burn multiple monsters from the inside out, among other things. Not to mention, he was making a joke.

"Come at me bitch!' I whisper yelled. Dean laughed, and Sam cracked a small smile. If Bobby was here, it would have been perfect. He always seemed to have a positive effect on any hunter's mood, despite being a grumpy man. I wrapped the green army jacket he got me around my body, oddly, feeling cold in the summer heat.

It's summer why am I- Oh no. Realization hit me like a truck, and instantly I drew the fist weapon I thought of, my pistol, and got in a defensive position.

"Something's coming."

My two companions reacted without a pause, drawing their weapons, getting back to back with me, so we had eyes on very direction. Rustling sounds came from the forest in front of me. My heart banged against my rib cage as my breathing got a little faster in anxiousness. Suddenly, a large, black, shaggy dog bounded out of the trees. When I say large I mean big enough to take on a full on tank. It's red eyes had a tone of playfulness, oddly enough.

I looked to Dean, who was staring in shock.

"It's a hell hound." He muttered.

I shook my head. "Last time I checked, no of us have made any demon deals. There shouldn't be one after us."

The hell hound tilted it's head, studying me curiously with it's eyes. I could usually tell the hostility level of a monster by their body language, and this one seemed to have the hostility level of a butterfly.

I put my gun in it's holster, and started to calmly and slowly approach the beast. Sam grabbed my shoulder, looking at me like I was about to stick my hand into a vampire's mouth. "What are you doing?"

"It doesn't seem hostile. I'm going to try and earn it's trust." I wiggled out of his grip.

Dean shook his head in disbelief. "Are you insane?!"

I nodded. "Probably."

As I got closer, the hell hound started sniffing me. Once I was close enough, it stared to bark playfully and wag it's tail. I laughed, relived I wasn't wrong.

"See? It's friendly." I started to scratch behind her ear. "Who's a good girl?" I cooed.

Sam sighed, a smile spreading across his face. "Leave it to Grace to befriend a hell hound."

The beast licked me, covering me in slobber.

"Aw, she's just a big baby!" I giggled.

"Ms. O'Leary!" A voice called out, coming from the left. It was male, but high pitched, hinting that the person speaking was young. The hell hound barked.

Suddenly a boy manifested from the shadows. He had pale skin, and messy hair the color of squid ink. His black eyes had dark circles underneath. The skull shirt hung loosely over his torso, and his black jean were ripped. When he saw me, he drew a black sword.

"Who the hell are you?" He growled, eyes going from calm to alert at the drop of a coin.

The hell hound bounded up to him, tackled him, and licked him.

"Ms. O'Leary! Off!"

Ms. O'Leary ran back to me, then nudged me towards the boy. I held out my hand, giving him a friendly smiled. "Hey, I'm Grace Singer. These are my friends Sam and Dean Winchester."

The boy studied us carefully, like he was trying to analyze our threat level. Considering the fact we were all older than him, heavily armed, and one of us was half angel, it was probably very high. "I'm Nico. What are you doing here? I haven't seen you around camp."

I raised an eyebrow. "We were just looking around. What camp are you talking about?"

"Camp Half-Blood. You know, the demigod camp?" He said it like it was an obvious fact.

I looked back at the brothers to see if they knew what he was talking about, but they looked just as clueless as I was.

Nico looked between the three of us. "Well you guys are either demigods or can see through the Mist, because you can see Ms. O'Leary."

"I don't think Sam and Dean are demigods," I looked at the two. "But, I think I remember my dad saying something about my mom's dad being immortal."

The boy nodded, his feature softening just the slightest bit, but enough to be noticeable. "Ok, follow me. I'm taking you to camp."
