"Can you make this thing go any faster?"

It had to be the third time Jo had asked, and Dean took a deep breath, keeping himself from snapping at her. He knew she was just worried, and probably afraid too, and snapping at her wouldn't help in the least.

"I have the gas pedal on the floor, Jo. Just…try and get him awake, if you can," he said, and that much was true; he was pushing so hard on the pedal that it would probably leave an indent in the floor mat. These cars were built for rough terrain, not for racing.

He heard Jo saying Castiel's name, probably shaking him, because he hadn't woke up since before they got in the car- and that was worrying both of them. Awake and alert was better than unconscious, obviously, especially if there was a risk the 'unconscious' part might be permanent.

But it wouldn't be, couldn't be. They were so close, about halfway to the visitors center, and they would meet up with the others there. Hopefully everyone had stayed locked up tight and safe in there.

"Hey, Cas…can you stay awake for me? We're almost there, okay?" he heard Jo saying, and he breathed a sigh of relief- Castiel was awake. It was an improvement, if a small one.

He wasn't ready for it when something exploded from the trees by the front of the car. He slammed on the breaks with a loud curse, and the vehicle went skidding, the side of it slamming into the wall of flesh that had blocked the road in front of them. He looked up in time to see the Spinosaurus stumbling from being struck, and he knew this was the only chance they would get- he shoved the gas pedal to the floor, and the wheels spun before finally biting into the dirt.

It was a narrow squeeze between the Spinosaurus' chest and the edge of the trees, and the front right corner of the windshield was snapped off, nearly ending up in the backseat.

"Jo! You guys okay?" he yelled, still pushing the car as fast as it would go- in the rearview mirror he could see the Spinosaurus turning, starting to move with a frustrated roar.

"Yeah, we're…we're fine, Dean!" Jo shouted back, but she definitely didn't sound sure of that. He had to take her word for it, though, because the Spinosaurus was gaining on them, growing larger in the mirror with every moment.

"Incoming!" he yelled, and he could see Jo twisting to see the dinosaur in the mirror. After a few moments of shuffling, she grabbed the gun and stood up in the back, taking aim at the massive animal and firing off two shots.

It didn't even seem to notice. Its charge certainly didn't slow, and even going as fast as the car could manage, it was nearly on them by now. He heard one more gunshot, and then the car was yanked to a stop so sudden that Dean jerked forward and slammed into the steering wheel.

It took a moment for him to regain his bearings, and by then warm blood was dripping down his face from his forehead, his head was throbbing, and he couldn't seem to stop his vision from swimming.

Jo hadn't fared any better. She was lying against the console, having been thrown forward between the seats, and she was struggling to get back up. Dean stopped her, though, because when he turned to find her he spotted the Spinosaurus, still trying to free its teeth from where it had bitten down on the right side of the backseat and yanked the Jeep to a dead halt from 30 miles an hour. Evidently it hadn't been the greatest of ideas, but it was quickly pulling free.

Dean did the only thing he could do- he slammed his foot back on the gas, the wheels spinning in the dirt again, hoping to get a head start away from the dinosaur when it pulled free.

Jo was struggling to get her rifle up and pointed when the Spinosaurus suddenly snarled in rage. Dean turned just in time to see Castiel kick at it again, this time the heel of his shoe striking it right on the eye, and the dinosaur finally wrenched free with a roar that vibrated Dean to the core. The car finally lurched forward, leaving the Spinosaurus behind for the moment.

"We can't outrun it!" Jo said, sitting on the console between the front seats facing backwards, her gun raised and ready; for all the good it would do, anyway.

"Yeah, I kind of know that!" Dean snapped, and then they passed the sign with the shape of a T-Rex skull on it, the arrow below pointing off to the left.

And he got another one of those ridiculous, stupid ideas.

"Hold on!" he yelled, yanking the wheel to make the sudden turn and nearly sending Jo into the console again, earning a glare from her.

"What are you doing?!"

"Something stupid, just keep an eye on Cas!"

"Not goin' anywhere…" Cas muttered from the back, his voice barely audible over the sound of the engine. And now, Dean could hear the heavy footsteps behind them again, and another roar from what was probably an incredibly angry Spinosaurus.

Dean imagined that it wasn't often a prey animal kicked a Spinosaurus in the eye and got away from the encounter in one piece. He couldn't help but feel a little pride that, despite being a writer, of all things, and having one leg torn open and infected, Castiel somehow found the strength and presence of mind to use his good leg against a fucking Spinosaurus.

He was pretty damn certain that Castiel was way too good for him.

"Do you actually have a plan? Because it's kind of catching up!" Jo asked, and Dean glanced back again. It was almost caught up, and he pushed down harder on the pedal, even though it was already to the floor. The path ahead of them was empty, and for once he didn't want it to be empty. He wanted that path to be full of angry dinosaur, right about now.

"Working on it!" he said, and the footsteps were right behind the car now, and Jo screamed and fired-

- just as the T-Rex stepped out of the trees in front of them.

Dean had to slam on the breaks to keep from running right into the dinosaur, and he heard the Spinosaurus snarl behind them.

For a moment, they were stuck sitting in the path between a furious Spinosaurus and a very confused T-Rex. Then, the T-Rex seemed to get with the program, and she stomped one foot down and bellowed out a roar that seemed to shake the whole Jeep. Jo clamped her hands down over her ears with a wince, and Dean had to make a conscious effort not to do the same.

"Come on, come on…" he muttered as the T-Rex shifted and the Spinosaurus snarled.

Then, all hell broke loose.

The Spinosaurus lunged forward and to the left of the Jeep, its right leg smacking the vehicle as it moved by them and snapped at the T-Rex. The T-Rex responded in kind, taking two massive steps forward and snapping its jaws at the Spinosaurus. The Spinosaurus responded by closing the gap between them and using its head like a battering ram, knocking the T-Rex off balance.

Dean covered his head, sure that the rex was going to fall right on the Jeep, but it managed to miss the car and stumble into the trees. With the Spinosaurus on the left and the T-Rex recovering by the tree line, this was the only chance they would get, and Dean took it.

He accelerated down to the floor again, and the Jeep jerked forward just as the Spinosaurus moved toward the T-Rex again. Its foot clipped the back of the Jeep, nearly sending it into a fishtail, but they pulled away just as the two behemoths clashed again.

Dean wasn't about to stick around and see who won, but when he looked in the mirror right before taking the curve, the Spinosaurus had its jaws clamped down on the T-Rex's back.

"Jesus Christ," Jo said, her voice breathless as she looked back at Dean. "You couldn't have warned me?"

"Wasn't really thinking about it at the time," Dean pointed out, wondering if his heart would ever get back to beating at a normal rate. "How's Cas?"

Jo crawled back into the backseat, and Dean held his breath for those few moments of silence that followed.

"He's okay," she finally said, and he let out that breath in a rush. "He's out, though," she added after a moment, but that much he'd expected. Since he'd been lying down, Castiel probably took less of a beating in the sudden stops and starts of the car, but it had still probably been a lot to deal with on top of everything else.

It felt like the longest fifteen minutes in his life, driving between the T-Rex's territory and the visitors center. Every moment he was waiting for one of the two behemoths to step out of the trees, this time with nothing to distract them from the tasty humans in the car. Their luck held this time, though, and the Jeep screeched to a stop at the base of the wide steps to the visitor center. He parked right behind another Jeep, one that looked pretty beat up, though maybe not as bad as theirs; not a T-Rex level encounter, that was for sure.

When he looked up at the center, however, his stomach dropped and his throat tightened with dread; the doors were halfway opened. He'd been hoping the visitors center stayed secure, and it obviously hadn't.

"Shit," he said, hopping out of the Jeep and handing his rifle to Jo. He couldn't carry Castiel and maneuver a rifle at the same time, and leaving Castiel in the car while they checked things out was absolutely not an option. Jo seemed to understand that, throwing his rifle over her shoulder, her own gun still held tightly in her hands as she hopped out of the Jeep.

Dean opened the back door and climbed in, immediately pressing his hand to Castiel's forehead. His skin was pale, damp with sweat and way too hot, definitely hotter than it had been back at the docks, and as Dean scooped him out of the seat, he barely got a mutter in response.

"Come on, Cas, just a little longer," he pleaded, carefully getting out of the car and nodding to Jo. She led the way up the steps, leading with her rifle through the open front doors and into the massive lobby.

Nothing much looked out of place. The T-Rex skeleton still took up most of the room, the stairwell arching up and behind it. He didn't see anyone, human or dinosaur, and Jo took the stairs slowly, her finger on the trigger.

"Think they went somewhere else?" she asked softly, and Dean shook his head.

"Nowhere else to go. Unless they have an emergency bunker somewhere," he pointed out, but he highly doubted that. Gabriel didn't have a single doubt that there would be problems; he probably would have laughed off the idea of an emergency bunker.

Probably wasn't laughing now, though.

They turned the corner into a long hallway, and standing halfway down it was a raptor, its head nearly hitting the ceiling when it straightened up and turned to look at them.

"Shit," Dean choked out, his grip tightening on Castiel as he took a step back. There wasn't a point in running, though; they wouldn't be able to outrun it. The raptor was already stepping toward them, nostrils flaring as it closed the distance, and Jo fired off a shot and missed.

The next trigger pull resulted in the click of an empty gun, and as she fumbled to get Dean's gun off her shoulder, the raptor broke into a run right toward them.

The next gunshots that tore down the hallway weren't from Jo; they were coming from the other direction, on the opposite side of the raptor. The raptor jerked and turned, stumbling as it tried to shift around in the narrow hall, and that was enough time for three more shots to ring out. The raptor let out a screech and fell, and on the other side of it stood Sam, looking bloodied and bruised but also pretty damn angry.

"I am so sick of those things," he said, motioning for then to follow him. "Quick, this way. There's more of them, but we have the control room barricaded," he added, and Jo stepped over the twitching raptor, Dean following more carefully to not jostle Castiel too much.

Sam fell into step beside him, giving Castiel a concerned look. "What happened? How is he?" he asked with a frown, and Dean snorted.

"Would you believe me if I told you a T-Rex bit him?" he said, the whole thing sounding ridiculous put into words like that. "He's got a bad cut on his leg. Really bad. It's already infected, Sam. Please tell me you guys have got a way off this island."

Sam nodded. "Chopper is coming in really soon. Trick is, we've got to get to the roof, and that involves going down the main hall. No telling how many raptors are still in the building."

"How much ammo we got?"

"Your gun, and three others. Only two of them have full clips though. It might not be enough."

They turned the corner and got to the door of the control room, and Sam knocked twice, looking both ways down the hall until there was the sound of metal scraping inside. The door cracked open, and Sam held it for Dean to carry Castiel in before he and Jo followed.

Dean was surprised when he only saw Gabriel and Charlie in the room. Both of them looked unharmed, unlike Sam, but he'd expected there to be more people here.

"Clear off a table," he demanded, and Charlie and Jo moved to shove monitors and books off an unused station. Charlie pulled off her jacket, rolling it up and holding it in place as a pillow as Dean laid Castiel out on the table.

Gabriel looked pale and a little ill as he stared at Castiel. If there weren't raptors down the hall, Dean would have taken the time to tell Gabriel just how much he held him responsible for this, responsible for Castiel's condition, but this wasn't the time for it.

"Where is everyone else?" he asked, and Charlie bit her lip and shook her head.

"We're all that's left, Dean. Us three and you three."

Well, fuck.

"How long till the chopper gets here, Charlie?" Sam asked, checking to see how many bullets were in his gun as Charlie checked the time on her phone.

"Ten minutes, tops. We need to get up to the roof," she said, and then she walked over and grabbed two guns, handing one to Gabriel and throwing the other over her shoulder.

Then, something hit the door hard enough to nearly knock it open. The heavy bookshelf shoved against it was the only thing that likely kept it closed.

"We need to distract them," Dean pointed out, and the room fell silent for a few moments before Charlie lifted her head.

"Gabriel," she said, the words coming out in a rush. "Did we keep the archive footage of Benny setting the Gastromimus' leg?"

Gabriel frowned. "Yeah, we didn't delete any of it, why?" he asked, but Charlie was already at the computer, typing fiercely.

"If I can route the audio from that footage through the intercom system in the dining room, the raptors should converge on the sound of the injured dinosaur instead of us," she explained, and Sam smiled with relief, looking over her shoulder.

"Good idea. Just hurry, the pilot said he wasn't going to wait."

Gabriel had moved closer to Castiel's side, and Dean very nearly growled when he noticed, putting himself between Gabriel and Castiel before he could get any closer. "Don't you fucking touch him. You've done enough to him," he snapped, and Gabriel went from looking a little sheepish to downright angry.

"I'm his brother!"

"Yeah, well, you sure don't fucking act like it!"

"Shut up!" Charlie snapped, her finger hovering over the enter button as something slammed against the door a second time. "When I press this, we have to haul ass. So get ready."

Dean immediately turned away from Gabriel, shoving down the anger and ignoring the throbbing from the cut on his forehead. He would have loved nothing more than to punch the shorter man in the face, to tell him exactly what he thought of his theme park, but right now he needed to focus on Castiel.

Castiel, who was shivering and muttering something that didn't even sound like English. He was so far gone, his skin burning, and Dean lifted him up as carefully as possible, cushioning Castiel's head carefully against his shoulder.

Gabriel watched every move, and Dean thought he could read a good amount of guilt in his expression as he watched.

He hoped Gabriel felt fuckin' guilty.

"Ready?" Charlie asked, and Dean looked around at their beat up group of survivors. Charlie and Gabriel looked exhausted, both of them clutching rifles like a lifeline. Jo looked like she'd stepped right off the poster for some Tomb Raider movie, all determination and smudged in dirt and blood, but still somehow put-together. Sam looked grim but ready to move, and Castiel…well.

Charlie pushed the button, and the scratching and banging at the door stopped after a few moments. Dean could distantly hear the awful wail of an animal in pain, but he knew that wouldn't fool them for long. Sam and Gabriel pulled the bookshelf away from the door, checking outside before letting Charlie and Jo step through, the girls taking point as Charlie led the way through the halls to the roof access. Sam and Gabriel walked in the back, protecting the only two of the group who had no defense.

Sam kept throwing Dean those sidelong looks, the looks that screamed 'are you okay' and that Sam wanted to talk about 'feelings', but right now all Dean wanted to do was get Castiel on that helicopter and to a hospital as quickly as possible. He didn't know how long a person could survive with this kind of wound and infection; 24 hours? Less? It had only been half a day and he was losing this fight.

And really, who knew what kind of fucking bacteria a T-Rex had in its mouth, anyway? They could carry some sort of prehistoric tetanus or something. (And yes, maybe the scientist part of his logic was getting a little lost after all this shit.)

"Guys!" Sam suddenly yelled, and Dean turned to see a raptor behind them in the hallway, nails clacking on the polished floors and lip curled into a snarl. It let out a harsh noise, and Sam fired at it just once, maybe hoping to scare it off.

No luck.

"Keep going!" Dean said, knowing they couldn't try to stand still and fight it out here in the hallway. They needed to keep moving, shoot when they had to, and get up to that roof. Sam walked backwards behind them, shooting again when the raptor got close, and it fell back a little-

Until two of its friends joined it, anyway.

"Here!" Charlie said, yanking open a door to a stairwell, and Jo made sure Dean stepped through with Castiel first. Sam was last to come through, firing the last few shots in the gun before yanking the door shut and sliding the rifle through the handle.

"It won't hold. Let's go," he said, just as Dean heard the distant sound of a helicopter somewhere above them. He took the steps as quickly as he could, the sound of the raptors slamming into the door reverberating through the whole stairwell, until there was a massive crash just as they opened the door to the roof.

"He needs to refuel, barricade that door!" Gabriel demanded, already heading for the fuel pump as the helicopter touched down, but there was nothing to barricade the door with up here- the helicopter supply racks were too big to move, as were the air conditioning units. Jo and Sam pressed their backs to the door, and the pilot leapt out of the helicopter, looking around in confusion.

"What's going on? What's the emergency?" he asked, eyeing Castiel, and Dean walked past him to the helicopter.

"Dinosaurs. Open this up, I need to lay him down," he said, and the pilot opened the door, giving Dean a look.

"A dinosaur broke out?"

"Not a dinosaur. All the dinosaurs."

The pilot looked a little sick, but was quickly distracted by Gabriel yelling that the pump was ready for refueling. Dean climbed carefully into the helicopter, folding one of the emergency stretchers down from the wall and laying Castiel down on it carefully, brushing his hair back from his forehead before he got back out of the helicopter.

Now, at least, even if he didn't make it off this island, Castiel would be safe as long as the helicopter got off the ground.

The wind from the blades of the helicopter was vicious, but he ducked and ran over to where Sam and Jo were struggling to hold the door to the roof shut, and he pressed his hands against the door between them. With every shove of the raptor all three of them were pushed back, even using all their strength to hold it shut, and Dean kept one eye on Gabriel and Charlie and the pilot, waiting for them to say the helicopter was ready to go.

He hoped it was damn soon. They couldn't hold this door shut for much longer.

The door shoved open again, and this time one of the raptors stuck its head through the gap, a shrill noise leaving it as it focused in on the humans. Dean, though, decided to take a page from Castiel's book- he backed up and kicked the raptor in the face three times before it finally yanked back and the door slammed shut again.

"So sick of these god damn dinosaurs!" he snapped, bracing against the door again, and Jo let out a strained laugh, her boots braced on the concrete as she pushed backwards against the door.

"Guys, we're good!" Gabriel yelled, and Dean watched to make sure the pilot, Gabriel, and Charlie all climbed safely in the helicopter. He looked at Jo and nodded.

"Go on. Once you're in we'll make a run for it," he said, and she looked like she was about to argue, but an equally stern look from Sam made her nod instead. She pushed away from the door and sprinted for the helicopter, climbing inside and turning to wait on them.

"On three?" Sam asked, and Dean had a flashback to clinging to that fence with Castiel and Jo, getting ready to jump. Before Castiel had started to fade so fast.

"Yeah. On three."

Sam counted down. On three, they both shoved away from the door, and Dean sprinted as fast as his feet could carry him, and even faster when he heard the door crash open on its hinges behind him.

"Come on!" Jo was screaming, reaching out and grabbing onto Sam's hand, yanking him up and into the helicopter. By the time Dean reached it he had to jump, because the pilot was already starting to lift off, and he barely scrambled in before it was too far off the ground.

Not too far for eight foot tall raptors, though.

One leapt and planted its feet on the skid, and the helicopter jerked dangerously to the side, nearly sending Sam sliding back out the door. Dean did the only thing he could think of to do- he hauled back and punched the raptor on the nose.

It screeched and its feet slid back and dropped off the skid, and the raptor went plummeting to the rooftop, the helicopter righting itself and pulling away and out of reach. Dean grabbed for the side door and pulled it shut, breathing hard as he stared at the metal, as if he couldn't believe that they had done it. That they were safe.

Most of them.

"Cas," he gasped out, rushing to where Charlie was sitting on the edge of the stretcher watching over him. She moved aside when Dean got there, though, and he sat down in her place, grabbing onto Castiel's hand and putting the other on his forehead. He was absolutely burning up, and it had been so long he'd been running this fever.

"Cas, hey, wake up," he said, shaking Castiel's shoulder to try and get him to come to, even for a second. There was no response, and he tightened his grip a little, shaking him again.

"No, come on, Cas, you've gotta wake up for me. We're going to a hospital, okay? We're almost there. Just a little longer," he pleaded, but nothing changed, the hand in his didn't tighten its grip. He leaned down and set his forehead against Castiel's, closing his eyes for a few moments; the silence in the helicopter was overwhelming, with no one willing to chime in with what they surely thought.

Dean knew better. Cas would make it.

He had to.
