"Go fish."

Dean sighed and reached for a card, ignoring Jo's triumphant grin in favor of studying his hand. Okay, so it wasn't the most comfortable situation to be playing cards, but there wasn't much else to do stuck in the back of an SUV in a torrential downpour.

But now that he was getting his ass kicked at Go Fish, he was seriously reconsidering their form of entertainment.

He noticed a couple of times that the deck of cards balanced on the seat slid to one side, then the other, as if the car moved just a little- but he didn't think anything of it. Not until he caught Jo looking out the windshield with a frown, and he followed her gaze to see Crowley sprinting toward the small building containing the restrooms, the passenger door of the front car left hanging open.

"What's up with him?" Dean said with a frown, and Jo shrugged.

"Maybe he really had to go. Lawyers are full of shit," she said, and Dean would have scolded her for the awful joke, but he was distracted. He was watching as Castiel's silhouette moved across the front seats of the other car, reaching out and pulling the door shut.

He was just beginning to wonder if he and Jo should go and join Castiel in the other car when there was a loud, metallic groan. Jo spun around in her seat to look, her ponytail nearly hitting Dean in the face as he leaned forward to look at the fence, a pit of dread forming in his stomach.

The huge metal fence was swaying; and pressing up against it was the massive form of the T-Rex, easily identifiable even in the dark.

"Dean. Dean, the fences aren't on," Jo whispered, her voice weak. Dean nodded, forcing himself to keep breathing, because otherwise he was just going to keep holding his breath as he heard the fence give way and the cables snap.

The T-Rex took two heavy steps outside the enclosure between the cars, and the sound that followed was unlike anything he'd ever heard. It was like an elephant trumpeting right beside his ear, but with a depth and friction to the roar that was bone jarring. He didn't even realized that he'd covered his ears in a panic until he saw that Jo had done the same thing, wincing from the sheer intensity of the sound. And by the time they lowered their hands, he could see the solid, muscular legs of the T-Rex moving over toward their car, coming up to Dean's side and pausing there.

"Jo, over, get over," he said, pushing her as far as he could toward the window on her side of the car, scooting away from where the dinosaur's nostrils were flaring, fogging up the outside of the windows. The T-Rex tilted its head, and for one moment that seemed to last full minutes, Dean made eye contact with it.

And he was sure it saw him, too.

The T-Rex moved and nudged its muzzle against the car. The whole vehicle jerked, wrenching a startled scream from Jo; Dean could see where the metal of the door had bent inward with just that small nudge. This car was like a tin can to the eight ton animal; it was crumpling like paper with every blow.

"It's okay, it's okay. Just stay still, she'll get bored with it," Dean insisted, though he didn't believe his own words, and he doubted Jo did either.

He suddenly remembered a friend growing up in Kansas who had a Border Collie- the dog was so obsessive about food that they had to hide its kibble in a tiny plastic puzzle box, and the dog had to move the panels on the top with its nose to expose the different partitions of kibble. That dog could sit there for hours, shoving the sliding plastic pieces with its nose, checking and rechecking every nook and cranny of the puzzle box for bits of kibble he'd missed.

Dean suddenly felt a whole lot like kibble.

The T-Rex's nose shoved forward again, and this time the impact was hard enough to rock the car back and forth dramatically, tires coming off the ground at least a couple of feet. Dean fell into Jo and heard a sharp smack as her head hit the window, but he didn't have time to check and see if she was okay- the frustrated dinosaur was roaring again, and up close the sound made his ears ring and ache, and he flinched and scrambled to get upright again.

The next hit came too soon. This time the momentum didn't stop, and Dean went tumbling into Jo again, their limbs tangling as the car creaked and finally tipped over hard on its side. Jo's elbow slammed into Dean's chest, and he tried to force air back into his lungs, his hands sliding on the cracked side window, which was now pressed against the muddy ground.

The car shuddered again, and Dean knew what was coming. "Jo!" he tried to yell, tried to warn her, but it came out choked and breathless. He saw her lift her head, caught a glimpse of wide, terrified brown eyes, and then the car lurched again. Dean's head smacked against the window as the car flipped violently onto its roof, and for a second, all Dean saw was static, like the snow on an out of range TV channel.

For that moment, he thought he would pass out. The sound of Jo's scream was distant and muffled and sparks were exploding in his vision, his head throbbing as he pulled himself back from the brink. He completely snapped out of it, though, when he felt cold, watery mud sluicing around his hands and shoulder that were pressed to the roof of the car.

He forced himself back to awareness just as the car groaned above them, and them the seat jerked downward, and Jo had to duck down so it didn't hit her on the head. Muddy rainwater was pouring in the broken windows, and he could only see one large clawed foot from where he lay, so he could only assume the T-Rex had its other foot on the bottom of the car. They were going to be crushed or drowned if they didn't get out of here. He could hear metal snapping over their heads, and the frustrated grunts and huffs of the T-Rex as she tried to tear the car apart to get to the humans inside.

Jo was just starting to try and kick out one of the cracked windows so they could crawl free when Dean heard a loud whistle over the pounding of the rain on the car. Seconds later the seat lifted up a few inches, as if the pressure was gone from it, and then Dean heard heavy footsteps moving away- along with a growl.

"This way!" he said, grabbing Jo and tugging her toward the side the T-Rex had been on; while closer to the dinosaur, this window had popped free entirely, and he crawled through the freezing mud and out onto the road. He looked up just in time to see the T-Rex collide with the small building, and one glance toward the front car confirmed his fears.

The driver's side door was open. That whistle had been Cas.

He helped Jo crawl free. Her skin was smeared with dark brown mud and bright red blood, but she didn't look like she had any major injuries, and more pressing matters were at hand, anyway. Dean's mind was already working, trying to think of everything he'd ever guessed about dinosaur behavior, anything that could be of use. Running wouldn't do any good; the T-Rex had excellent eyesight, and could follow a scent for miles. They needed a distraction.

"I t-think it ate Crowley," Jo said weakly, her whole body shaking, whether from the cold or the shock he didn't know.

Wait.

The T-Rex just ate. And it had been so curious about the car, nosing it, pushing at it…it had seen the cars, but never had a chance to investigate them, till now.

"I have an idea. Tell me when it finishes eating," he said, stumbling to his feet, shoes sliding in the mud as he rushed toward the front car. He dove into the front seat, praying to any god who was listening that these weren't custom made for the program, that they were modified, mostly normal electric cars.

He tore the plastic off the console underneath the steering wheel, for once not regretting his brief foray into juvenile delinquency as he sorted through wires and found what he needed.

"Dean, it's done. It's looking around," Jo said from where she stood outside the car, and Dean tried to make his shaking, wet hands move faster.

"Almost done," he said, and he heard a low rumbling noise from the T-Rex, then footsteps.

"Dean, we have to go!" Jo said, grabbing his shoulder- but at the same time, the engine roared to life and the headlights came on. Dean slid out of the car, then reached down and shoved the piece of plastic he'd removed from the console down against the floor and forward. It wedged tightly against the pedal, and the car's wheels spun in the mud as Dean jumped clear. The car lurched forward and took off with a grind of protest from the engine, but it did what he needed it to do.

He grabbed Jo and pulled her down to the ground underneath him just as the shadow of the T-Rex fell over them. Just when he was expecting teeth to slice into them, he felt a rush of air go by, and he looked up to see that the T-Rex had walked right over them and was now pursuing the vehicle as it raced down the road.

It had worked. He took a gamble, assuming that curiosity would win out once hunger was satisfied, and he'd gotten it right.

At least the lawyer had been good for something.

"Cas," he said, his voice breaking as he stumbled to his feet and rushed back over to the destroyed building. Ignoring the bits and pieces of lawyer that the T-Rex hadn't found palatable, his eyes searched the broken wood and wind blown fern leaves covering the ground until he finally saw pale skin through the mess. He rushed to Castiel's side, dropping down next to him and pressing a hand to the writer's back, fearing the worst.

"Cas? Cas, come on, man, wake up for me," he begged, shaking Castiel a little with one hand as he brushed debris away from his body with the other. Castiel shifted and moaned under his hand, just as Dean caught sight of the dark red blood soaking the denim of his right pant leg. Too much blood. Even if Castiel was awake, he wasn't going to be walking.

Dean tore his flannel over shirt from his shoulders; it was soaked and muddy, but it would have to do for now. He found the tear in Castiel's pants, a long rip starting just below the knee, where the blood was darkest on the denim. He wrapped the shirt around Castiel's leg and pulled tight, earning a pained moan from the unconscious man.

"It's going to come back," Jo said, having caught up to him, but looking pale faced and ashen at the sight of what was left of Crowley. Dean set his jaw with determination.

"We're not leaving Cas," he said, carefully turning Castiel over onto his back. He was definitely out of it, eyes only opening for a few moments before he was out again. They would have to inspect the damage later, because Jo was right; the T-Rex considered this paddock and the area around it to be its territory. It would come back and defend it as soon as the car ceased to be interesting.

He slid one arm under Castiel's knees and the other behind his shoulders, bracing himself and lifted the slender man bridal style in his arms. "Let's go. That way," he said, nodding his head away from the paddock. Jo nodded and started jogging toward the trees, and Dean made sure Castiel's head was pillowed against his shoulder safely before he followed as fast as he could manage. They needed to get as much distance between them and this paddock as quickly as possible.

They ran until they physically couldn't put one foot in front of the other. It seemed like forever, though it couldn't have been more than fifteen or twenty minutes, not in their condition. Dean finally saw a low outcropping of rock, just enough space under it for a makeshift shelter, and he called out to Jo and jerked his chin toward it.

Relief washed over her features as she moved to the outcropping and ducked underneath, and Dean followed, carefully laying Castiel down on the dry ground before sitting down himself. The water was dripping off the outcropping so quickly that it was almost like a thin waterfall was shielding them from sight back here. Castiel's eyes fluttered open again, but his gaze was unfocused as he blinked and took in short, harsh breaths.

"Dean…?"

Dean was already moving to Castiel's side, close to his injured leg, ready to see the damage. "I'm here, Cas. We got away, we're all good."

Jo snorted. "Except for the lawyer."

"He doesn't count," Dean muttered as he untied the flannel and pulled it away from the wound. He was suddenly glad for his need to carry a pocket knife with him everywhere- hey, they came in handy for a lot of things- and he flicked the knife open and carefully cut away the denim, peeling it back from the wound and wincing when Castiel tensed and made a choked, pained noise in his throat.

"Relax, I've got you," he said in what he hoped was a reassuring tone, even as he studied the wound and nearly all the hope drained from his face.

Just below Castiel's knee was nearly eight inches of shredded, torn flesh, as if one of the T-Rex's teeth had caught the flesh and just ripped upward. Maybe it had; he couldn't think of what else could have done this kind of damage. If he had more light, he was fairly certain he would be able to tell that the hints of lighter color in the wound were actually glimpses of the bone showing through the destroyed flesh and muscle.

"That b-bad, huh?" Castiel said, his voice even rougher than usual, every word on the verge of cracking. Dean forced the frown off his face, because Castiel had to have some hope. Dean wouldn't let him give up, wouldn't let him down. He shook his head and turned the flannel to the clean- well, the cleaner side, wrapping it back around Castiel's leg.

"It probably feels worse than it is. You'll be fine, Cas," he said, and he could feel Jo's eyes on him, because she knew, too. She knew as well as he did that if Castiel didn't get help, and soon, he was going to die.

"Liar," Castiel said with a breathless laugh, but it quickly turned into a ragged sob as Dean yanked the flannel tight again, whispering an apology as he did. Castiel couldn't afford to lose any more blood.

"I mean it. You're getting out of here, understand?" he said, reaching up to touch Castiel's face gently, trying to get him to focus through the pain. Castiel leaned into the touch and nodded, his chest rising harshly with each ragged breath.

"What now?" Jo asked, her knees pulled up tight to her chest as she shivered. Dean looked out at the rain, weighing their options.

"We have to wait until the rain lets up. We won't last in that," he said, his stomach churning with anger at himself, that he couldn't do more for Castiel or Jo. "They said this storm was moving fast. We'll start walking again as soon as the rain gets lighter."

Jo nodded, breathing into her hands to try and warm them. Dean was cold too, his fingers were partly numb, but all the same he was willing to share what little body heat he had to spare.

"Come here," he said, scooting closer to Castiel, who was unconscious again. He pulled Jo in close and then lay on his side on the hard ground, keeping his back pressed close to Castiel to try and share the same warmth with him. He wrapped his arms around Jo, rubbing her back gently. She pressed her hands to his chest to try and warm them up, and he could feel her shoulders moving minutely with tears that she was trying to hold back. She was a tough girl, the type to not cry in front of anyone if she could help it.

He kissed the top of her head, holding her until she finally fell asleep. He stayed awake, listening to every sound of the forest beyond their hiding place, waiting to hear the inevitable sound of heavy footsteps and that mind numbing roar.

Sam was on his feet the moment Meg turned the corner into the control room, looking soaked to the bone and thoroughly frustrated. Behind her was Bobby, his rifle slung over his shoulder and his khakis dripping on the floor- but his stormy expression was enough to draw Sam's attention.

"Ruby's not in the building. But there is a Jeep missing from the garage," Meg said, and it wasn't hard to put two and two together. Ruby had probably taken a Jeep to get down to the boat after she started whatever program had brought down the system.

The question was still why, but they couldn't take the time to look for the answer to that right now.

"Are the raptor fences still up?" Charlie asked Bobby, and when he grunted an affirmative, her shoulders sagged with relief.

"Lucky for all of you, they're the only fences still up. And only 'cause I insisted they run on a separate breaker in the system," Bobby said, focusing on Gabriel, who had gone unusually quiet in the crisis. "I heard your people are out in the cars?"

Gabriel nodded. "My brother. And Dean, Crowley, and Jo," he said, leaning back against Charlie's desk. The redhead was flipping through a thick manual on her desk, one hand turning pages, the other on the keyboard.

"We have to go get them," Sam said, looking at Bobby pleadingly, and the man nearly laughed.

"You're kidding, right? We'd only be putting ourselves on the menu. We need to wait till the fences are back up. If they stay inside the cars, they've got a shot."

"No. No, I'm going, with or without any of you guys," Sam snapped, pointing toward the door. "They're sitting by a useless fence with a T-Rex on the other side, and you want to wait and see? I don't think so. I'm taking a car, and I'm going to get my brother."

He turned to walk out, but the hunter's hand clamped down on his shoulder, the gruff, quiet exterior hiding a grip of steel. Sam pulled free and looked back at him, waiting as the man stared him down, one hand still set on his rifle.

"You ain't takin' no for an answer, are you?" he asked, and Sam snorted.

"No. I'm going. I don't care if it has to be alone," he said, and Bobby sighed.

"You'll need someone out there who knows these animals," he muttered. "I'll go with you, keep watch. But we're goin' straight to that paddock and coming straight back. No field trips and no heroics."

Sam nodded once, not waiting for Gabriel's opinion on the subject, because right now he really couldn't care less what Gabriel thought about anything. Bobby followed him into the hallway, and they both paused when they heard footsteps running to catch up to them.

"What, you boys think you get to have all the fun?" Meg said with a smirk, falling into step next to them.

"You sure you want to come?" Sam asked, though he didn't slow down. The longer they put this off, the more danger Dean was in.

"Oh, don't give me a 'girls in survival situations' stereotype lecture. I'm coming along. We'll take two Jeeps; they're only made for four people, after all, and we're aiming to bring all four of them back, plus three of us," she pointed out, and Sam had to admit, she was right. Two Jeeps would be easier and safer.

They picked two hard cover Jeeps that were ready to go, and Bobby drove the first with Sam in the passenger seat, Meg following in another Jeep. Bobby didn't feel the need to try and make conversation, and Sam certainly wasn't in the mood, either; plus, he was watching out the window for any sign of escaped dinosaurs. The ride was silent and tense, especially when they found that every gate they pulled up to was already open.

"Someone manually opened these gates. They ain't made to stay open; they default to being closed when they lose power," Bobby said, his voice low as they pulled through the giant wooden gate. Once past that bottleneck Bobby sped up considerably, so it only took half the time of the tour cars to get to the Tyrannosaur paddock.

Their headlights lit up a scene of twisted metal and scattered debris.

"Dean!" Sam yelled before he was even out of the car, and he fumbled to turn on his flashlight as he ran to the overturned car, dropping to his knees in the mud. He shined the light in the passenger compartment, but it was empty, only shattered glass and mud inside.

That didn't mean they were safe, though. He stood up and yelled Dean's name again, earning a hush from Bobby, who had his gun at the ready. Sam ignored him, trying to find the other car, but drawn inevitably to the ruins of the half demolished building.

He slid to a sudden stop when he nearly tripped over a leg- a leg that wasn't attached to a body. And judging from the black fabric and the fancy, shined shoe, he knew who it once belonged to.

"I think this was Crowley," he said, his voice thick with the urge to throw up, and he heard Bobby snort and move something off to his left.

"Yeah, I think this was, too."

"Boys! The other car!" Meg yelled over the rain, and Bobby and Sam gratefully took the excuse to get away from the carnage, running to catch up with Meg. She was nearly past the paddock, and Sam caught sight of the other car, rammed up against the edge of the tunnel leading away from the fences. The roof of the car was half peeled away, and the front was a crushed mess.

But, once again, there was no sign of Dean, Castiel, or Jo.

"You think they got away?" Sam asked, looking over to Bobby, who was pulling a piece of plastic free from where it was wedged in the footwell of the driver's seat.

"Someone got a chance to rig this car. They might've gotten out of here while the rex chased the car," he pointed out, tossing the plastic aside. Sam felt a surge of hope- the only body parts they'd found were obviously bits of Crowley, and there was no sign that anyone else had been eaten- unless the T-Rex swallowed them whole. He pushed that thought out of his mind the moment it crept in.

Sam looked down at his feet, his light shining on the footprints Bobby's boots made in the deep, sticky mud- and he realized he'd been so busy looking for bodies that he missed the obvious. He ran back to the road by the paddock, sweeping his light over the ground until he found what he was looking for.

There were definitely two distinct sets of footprints, leading through the mud from the wreckage of the building into the trees behind it. Bobby joined him and added his light, frowning a little as he stared at the footprints.

"One of these are the girl's. Too small to be Castiel or your brother," he pointed out, and Sam had to agree. So Jo and one of the guys had gotten away, but which one? Was it Dean or Castiel who had made it out?

That pit was back in his stomach, and deepening by the second.

"We should follow the tracks," he blurted out, and Bobby reached over and smacked him on the back of the head.

"Did you listen to a word I said back there, y'idgit?" he snapped. "No field trips, no heroics. We need to get back and help Gabriel and Charlie get this place running again. Two of them are alive, at least, and you should be thankful for that much. You won't be doin' your brother any favors tryin' to find him in this mess and gettin' yourself killed."

Sam wanted to argue. He wanted to grab that gun and go searching through the forest, find his brother, because he didn't want to think about if he found the survivors and Dean wasn't one of them. Or if Dean was one of them, and Castiel hadn't made it; he couldn't imagine how much that would hurt Dean.

But he also knew Bobby was right. They wouldn't do any good stumbling around out here; the best thing they could do was help get those fences up and running again before more of the dinosaurs figured out they could escape.

The decision was out of his hands, though, when they suddenly heard a roar- and it sounded far too close for comfort.

He and Bobby both turned and ran for the car. Meg was already climbing into hers, and just as Sam grabbed the door handle, he heard the trees shift and branches break- and he turned to see the T-Rex just in the tree line, its reptilian eyes locking on them, dark skin shiny from the rain.

"Go!" he yelled at Bobby before he was even fully in the car, and he yanked the door shut as the car peeled out. Meg's Jeep pulled ahead, and Bobby wasn't far behind.

But neither was the T-Rex.

She roared again, and Sam flinched at the sound, which was followed up by the rear of the car suddenly jerking to the left. Bobby struggled to keep control of the car on the slick, muddy roads; it was hard enough without eight tons of dinosaur trying to knock you off the road.

Then Sam looked in the side view mirror- and it was full of teeth, right above the sticker that practically mocked him with the words 'Objects in mirror are closer than they appear'.

Those teeth were fucking close enough, thanks.

"Faster!" he shouted, turning to look behind the Jeep just as the T-Rex's head smacked into the side of it again. The car jerked and nearly went off the road again, but at the last second the tires bit into the dirt and regained traction, and when Sam looked in the mirror again, the T-Rex was slowing. Evidently they weren't worth chasing all the way back to the main gate, just worth chasing long enough to force them out of what she considered her territory.

Sam let out a slightly giddy laugh, the fact that they'd just had to run from a T-Rex finally sinking in. And they'd been in a car; how had Dean and the others felt, trapped and on foot next to that thing?

"Think Gabriel will have that on the tour?" he asked, only half joking- there was a heavy hint of bitterness in his tone, because for just a moment, he imagined Gabriel actually thinking it would be a good idea.

He wouldn't put it past him.
