Sailor/island AU!! I've been wanting to do something like this for a while.
Lots of POV changes, sorry.

Cas-

The cold water lapped at my chest, and occasionally splashed up into my face. Where the hell was I? I remember.. Shit. I remember the boat getting caught in a storm, and I remember us crashing into a cluster of rocks just off an island.

I sat up and rubbed my head. I had washed up on to the sand, and I could see the wreck not to far up the current. I needed to find my crew. Benny, Charlie, Garth, Gabe, Balthazar, Kevin, Bobby, and his wife, Ellen. Not to mention, most importantly, Dean. My skull throbbed, but I stood up anyway.

"Hello? Anyone?"

"Captain!"

"Benny! Oh, thank god."

He threw his arm around me.

"How long you been up for, mate?"

"Just about a minuet. You?"

"God, at least half an hour. I haven't found anyone else, I was heading towards the ship."

"She looks horrid. Dean is gonna be pissed."

The vessel was his, but I was better fit to be captain, according to credentials and shit. He hated me at first, but then we had sex and he lightened up a bit. That was a year ago. Felt like a lifetime. I could see the glittering word Impala still attached to the side of her.

"Yeah, no doubt. I wonder if he can fix her up this time."

"Doesn't look like it."

We were talking so causally, as if we weren't trapped on an island. We were talking about fixing up the ship, and how Dean would do it like we knew he wasn't dead. The thought churned in my gut, and I felt lightheaded.

"Ya'll right, Cap?"

"Yeah, musta hit my head pretty hard or somethin." I brushed off my worry. Dean was tough. I should be more worried about Garth and Kevin and Charlie.

"Hey!!" Benny started waving his arms, trying to catch the attention of someone up on a hill. Two people.

They saw us and waved back, then one started sprinting down the sand dune. As they came in to view, I saw that one of them was Charlie. The second Balthazar, my cousin.

"Heya, bitches!" Charlie was too hyperactive, as usual.

"Charlie, Balth." Benny nodded.

I didn't say anything. My head still hurt like hell.

"Cap'n?" Benny asked.

"Hmm? Oh, Hey."

"So, four of us." Balthazar took charge as my third, as my second wasn't here. "We have the Captain, Me, Benny, and Charlie. We're still missing..."

"Kevin, Bobby, Ellen, Garth, Dean, Gabriel." I listed flatly. I wasn't in the mood for all this talking.

"Right. Me and Captain Salty here were just heading back to the Impala to check for supplies and people." Benny smiled through his accent. I nodded. We were almost there.

"Well," I started. "We're going to have to find a place to camp. It looks about midday, and we'll reach the ship a few hours before sundown. We can't seek shelter in the wreckage, we have no idea if it might collapse, but we can get supplies. We need water, alcohol would be nice, any cooking things, nets, fishing rods, axes and other weapons. Probably some medical supplies as well." The more I talked, the more my skull throbbed, but I was these people's captain, even if I was their friend.

"Aye Aye. Anything you think might be useful, grab it."

We walked in silence, and I tried to think back to when I last saw Dean.

-

The boat was rocking wildly, being thrown back and forth by the waves and wind. I was trying to turn the wheel, but the friction was to much and it was spinning out of control.

"Captain, you're going to get your hands taken off if you try to hold on to that!! We need more men on the sails!" Gabriel was shouting. I could scarcely hear him even though he was right next to me.

I let go of the wheel and rushed down the steps. There were four people working with the ropes. I pulled and steered as best I could, until, out of the corner of my eye, I saw someone fly overboard. I handed the rope to whoever was on my left and rushed to the side of the boat. Dean was hanging on to the side for dear life, his hands slipping on the wet wood.

"Shit! Hold on!"

"What the hell does it look like I'm doing, Cas!!"

I grabbed his arms and tried to pull, but my feet didn't like the slippery deck. I pulled with all my might, turing my head to the left, just in time to see jagged rocks right in front of us. I barely heard the call of "Brace for impact" before all went dark.

-

I had no idea where Dean could be. It was most likely that he was dead. I could picture his limp body, impaled by one of the rocks that stuck up off shore. The image made me sick to my stomach. We'd just have to keep going until we had proof.

--

Dean-

"Brace for impact!!"

Cas' hands slackened around my own, and I tried to keep my grip, but I was flung into the open ocean. The storm was still raging all around me, churning the waves so I could barely keep my head above the foam. I could see the outline of an island when lighting struck, and I did my best to swim towards that. Wood was flying everywhere, and I managed to grab a hunk to help me float. I heard a loud splash and more water impaired my vision even farther when a body landed near me.

"Kev! Kevin!!" Even if he was awake, there was no way he could hear me. I grabbed the back of his shirt and pulled him up to me.

It seemed like forever until we reached the island. I needed to he away from the shore so I didn't get sucked back out if the tide rose later. I dragged Kevin over the soaked sand, all while clutching the huge gash in my side. I didn't know if anyone else was alive. Hell, I didn't know if I would live. I was bleeding profusely, but it barely hurt. Adrenaline and fear and the will to stay alive kept me going until I found semi-shelter under a tree. I peeled off my shirt and did my best to stop my bleeding, before passing out.

-

I was stiff when I opened my eyes. Someone was moving next to me, treating the wound I couldn't remember getting.

"Kevin?"

"Heya, Dean."

"How the hell am I still alive."

"Don't ask me. I've been trying to clean it out with no water and salty cloth, so I'm just as surprised as you are."

"Where is everyone?"

"No clue. I went overboard and woke up here."

"We need to find them."

Cas

"You can't move. An inch."

I groaned.

"Go find them. I won't move."

"How will I know where you are?"

"I don't know! Draw a huge-ass arrow in the sand?"

He rolled his eyes. I couldn't see his face, but I could tell. I heard him get up to leave.

-

The next however long felt like years. I couldn't move my head to survey my surroundings, and if there were animals here then I was easy meat. At long last, I heard Kevin.

"Dean! I found Bobby, Ellen, and Gabriel!"

Good, that meant someone else was alive. And Bobby was good at this stuff.

"Thank god. Any fresh water?"

"Yeah, there's a water fall not to far away."

"Good. Hey, Bobby. Ellen."

"Hey kid. Looks pretty bad, that does."

"Yeah."

"Not even going to say hi to meee?"

Now I rolled my eyes.

"Gabriel, not in the mood. Did you guys find Baby? How bad is she."

It was silent for a minuet.

"Pretty bad, Dean-o. Sorry."

"Shit."

It was quiet again, except for my occasional grunts of pain as Bobby worked on my cut.

"Okay, boy. You should be able to at least move now. Take it slow to start."

I groaned and sat up. My side did hurt, but I'd had worse. It was a very tropical island, from what I could see. We were in a pretty sheltered area, the tree over head was quite low and the leaves brushed the top of Bobby's head. I was laying on a mix of sand and squishy moss, almost all the water from the storm had dried up.

"Alright, get me up."

"No sir. You need to stay down."

"There are leaves protecting us right now, but this isn't shelter. If there are wolves or any kind of predator I'm dead meat. We need to find the others and some sort of cave. And, I know we're all happy pals or whatever, but I'm still Ca-Castiel's second so we're going to find better shelter." I had stopped myself before I used my nickname for the Captain, but Bobby noticed.

"All right then. Kevin, Gabe, help me get mister-second-in-command up please."

They pulled me up and Bobby put one of my arms around him. I hissed in pain at the sudden movement. We started moving down the sand to the waterfront.

"If we're going to find the rest of the crew, they are either still in the ship or washed up on the beach." I grunted.

The sun was scorching hot. If we didn't want to get fried, we were going to have to find mud. I limped along for about ten minuets, until more figures started rising up over the sand dunes

--

Cas-

The boat was close now, and we had a closer up of the rock- more like a mountain- we had hit. There were a few caves, or at least intents, in the side of the rock, and a flat spot with trees on top.  We hadn't found anyone else, so we were still missing four people in the crew. I was worried about my brother, Gabriel, but honestly, more about my boyfriend. That might've been because I saw Gabe jump overboard before we went down, and he didn't hit any rocks, but Dean more like flew away from the boat towards the rocks. I guess I would find out here soon enough.

We walked for a few more minuets, before four people made there way up and over the dune, into our line of vision.

"I think that's everyone, Cassie!" Balthazar smiled.

Charlie elbowed me in the side. She and Bobby were the only two that knew about our relationship. I glared at her and started waving to the on comers. Gabriel waved back and started running down the sand.

"Not everyone." I counted the heads again. "Where's Garth?"

Balthazar stopped. He and Garth were a pair of very surprising friends.

"Maybe he's back on the ship." I nodded as Gabe sprinted at us, throwing his arms around me.

"He little bro! We have Dean, Bobby, Ellen, and Kev."

"All we're missing is Garth." Benny said for me, because I was still getting the life squeezed out of me. Gabe noticed and let go of me.

"We should probably wait here for them, it's pretty flat, and draw out a plan for getting stuff out of the ship here in the sand." We were right by the base of the huge rock-mountain thing. "Is anyone too badly hurt to go into the ship?"

"Dean, probably."

"Dean?" I tired to keep my voice steady as I attempted to push thoughts of Dean, too badly hurt to help with supplies.

"He got cut open on a spike or something. There's a huge cut in his side. I think his ankle must be twisted too, but he refuses to be carried or get any help at all except for some support."

Then that must be Dean with his arm around the other figure. Who, now, was starting to look like Bobby as they got closer.

We waited for a few minuets for the rest of the crew -munis Garth- to get over here. Dean did not help my concentration. He was hurt, dirty, and shirtless, and I couldn't keep my eyes off him as I drew the plan in the sand.

"O-okay. The storage is on the lower deck, so it shouldn't be to had to get to. I can already see some stuff that's fallen into the water, and this seems to be some sort of intertidal zone. The water is shallow, but watch out for oysters. They're delicious but don't cut your foot open it hurts like hell, as you won't be able to walk. Gabe, Charlie, Kevin, go together to the other side. I'll take Balthazar, Benny, Ellen, come with me.  Okay. Let's go."

"Hey! Woah! What about me?"

"Dean, you're hurt."

"I can still help."

Dean started to stand up from where he was leaning against the rock. I instinctively moved forward just a little, and was glad I did a few seconds later when he collapsed. I grabbed him before he hit the ground.

"Yes, you can help. When people get a armful of supplies, they can bring them here. Look through them and see what can actually be used."

"Fine." He grumbled, sitting back down.

"Bobby, do you mind helping him with that?"

"No sir."

"Okay, let's go."

In the first few minuets, I managed to grab a fishing net, bait, two metal poles that would help with something, two first aid packets, and an armful off that whisky that Bobby never fails to bring aboard. I took out my load and handed them to Dean. As soon as he saw the whisky, he smiled and grabbed a bottle. It looked like other people were bringing in pretty good hauls, too. I saw Charlie dump a whole pile of fishing supplies next to Bobby. I don't know when he got here, but after about an hour, Garth joined in. It was nice to know he was okay. At one point, I managed to make it to Dean's chambers, he got his own as second in command, and I got some clothes for him, a surprisingly dry picture of him and Sammy, and his dad's army dog tag, before finding my chambers.

Sadly, mine weren't as dry. I fished out clothes for myself and any of the other guys, a locket Dean had got me for my birthday from a traders market in Africa, and an axe. Yes, I kept an axe in my room. The sun was going down the next time I went back on to the beach. Dean and Bobby had put most of the stuff in one of the little caves in the rock, and had set up a lean-to in front of another, bigger one. Dean looked a lot better, with wound treated by whisky and some freshwater that Garth had got from an apparent waterfall not to deep in the woods, and Wales up with a ripped sail. We had a barrel half full of fresh water now, but still not much dinner. In the remaining minuets of light, I set up the foraging net on some spokes a little up and out in the water. Luckily, nobody got hurt in an oyster, but Benny found a few and cooked them. It wasn't much, but it was enough.

--

Dean-

I woke up the next morning before anyone else. I moved out of the cave and into the sun. I grabbed some stuff and slowly limped along until I found a kinda flat rock that stuck out enough to go fishing off of. I bated my hook and cast it out, then waited. The water was extremely cold from when I had touched it earlier, so that meant more fish. After about an hour, I had caught seven fish. That was pretty impressive, but I kept going until I had nine. I made my way back over to camp and started up a fire to roast the fish on. I was hoping people would wake up to the smell of fresh fish. Luckily, we had found ten plates in the wreckage, so this might be like a camping trip. If we ever got rescued. The next person to wake up was Benny, followed by Charlie. By the time the fish were all done, everyone was up and hungry. We talked and laughed like we were just stopping on a beach to eat and get a break from the sea. We all knew that wasn't true. We were stranded.

I'm gonna put out a part two but I haven't updated in a while and this is almost 3000 words.
