Title: Enemies' Enemies.

Disclaimer/note: I don't own anything to do with Supernatural, so much so I don't even watch much more than Castiel's episodes. So pardon my ignorance and the mistakes I may make due to my unfamiliarity with this universe.

Set/Summary: No, you did not need another version of post8.21, there are so many! And for good reason. It's such a brilliant opportunity for a 'Dean (and Sam) taking care of Castiel scenario' that it feels impossible to leave it alone.

Pairing: canon extent Destiel and Megstiel.

Genre: Hurt/Comfort you glorious!

Kicking into action a hesitant, unsure and stunned Dean, Sam held on to the passenger side door of the Impala, stepping round it, but knowing that he was too weak and too slow to complete what needed done, himself, "Dean! You have to get him away from the middle of the road! It's not as if there never are any cars going past around here."

Dean nodded and held a hand up towards his brother placatingly, "it's ok, I've got it." And then he was by Castiel's side, lifting him up by the shoulders from the back. "Son of a bitch," he muttered. He would deal with whatever injuries needed dealt with later, Sam was right, getting the wounded soldier away from any possibly passing cars was more important.

"Soo..ry. Caa..can't," Castiel tripped over his words and his own feet as well, both hands going to his stomach, almost bringing both of them down onto the asphalt.

"Damn it Cas!" Dean readjusted his grip, manoeuvring one of Castiel's arms over his shoulders, but replacing the hand he pulled away from the angel's stomach with his own. There was a lot of blood there and he wanted to make sure enough pressure was applied. Castiel panted, head lolling, blood dripping from his mouth. "Don't you dare pass out on me!" Dean urged, forcing a few steps out of Castiel.

Despite Dean's earlier instructions, Sam was by the angel's other side at this point, letting the injured celestial lean onto his arm. His brother gave him a thankful glance as he opened the back door and they dropped Castiel onto the seat where their friend curled up puffing out moany breaths as the moving around aggravated his wounds. Dean stared at him for a moment frowning before taking the wheel again. "Try to find out what happened," he grunted at Sam. And how can we help, he added to himself, but didn't say. By Sam's understanding expression his brother knew what he meant anyway.

Sam stretched his long arm towards the back seat, settling it on Castiel's forearm, "Cas," he prompted kind and soft, "can you tell us what's wrong?"

"Crowley has the tablet," Castiel groaned, wanting that piece of information out the way. The brothers should know his greatest mistakes before being pushed into helping him.

"Nice job," Dean snarled, "is that why we couldn't have it? And now we're good enough to come to? What, no answer Cas?"

"Dean." Sam warned, "he's not really well enough for weighty conversations like that. Look at him."

"He should've thought about that before he flitted away with the angel tablet," Dean grumbled, but his eyes travelled to his mirror anyway, apprehensively assessing Castiel's condition in the light of the streetlamps of the small town they happened to pass through. Something major must've went down to put the angel in the state he was in, Dean knew that and he also knew that it worried him, even though he did not intend to show affection towards Castiel for being too pissed off with him. The hunter gulped, repressing a concerned expression, but could not avoid concentrating on how pale his friend looked, how bloodsoaked his clothes were, how painridden and woozy his expression was, how rigidly he held his stomach, how his eyes closed repeatedly as if he would've been too worn-out to be able to keep them open.

"How bad did Crowley hurt you?" Sam asked in his compassionate voice.

"I need," Castiel swallowed, "medical assistance."

"You don't want us to take you to a hospital do you?" Sam checked for safety's sakes.

"Still glowing," the angel said as way of clarification.

Sam sighed uneasily, "we can sew up a surface wound okay, but that one seems deep and we can't exactly perform that kind of surgery, Cas. Not to mention you need blood."

"I could heal myself if.." Castiel took a little rest by closing his eyes and taking a couple of breaths, "it hurts too much to concentrate."

"Pain meds, we have a lot of those," Sam assured him, "but we'll need to give them intravenously, I don't think it would be a good idea to put anything in your stomach right now. Dean, how far are we from home?"

"Not far," Dean kept glancing at his mirrors to check on Castiel. Out of his two passengers it was the angel who was paler at the moment. "We'll reach the turnoff in a few.

"I'm sorry.." Castiel wheezed, scrunching his eyes closed and stifled a moan by turning his face towards the upholstery and muffling the sound.

"It's okay Cas, don't talk just now, keep your strength," Sam reassured.

"No I'm sorry for..this," Castiel pointed towards his lips and made a half hearted attempt at catching what came out his mouth into his palm as the brothers watched horrified how Castiel's clothes, the seats and the floor mats became covered in blood and what could only be bits of organs and intestines.

The younger Winchester looked away and tried to concentrate on his own breathing, he tried to make sure he didn't throw up at the sight himself, riddled by the damage of the trials as he was, but Dean shouted at him. "You need to hold Cas' head up Sam, right now!" The older brother urged, "he's passed out and do we know what happens if he chokes on his own blood!"

"On it, on it!" Sam rolled the window down, but set a hand out to do as he was asked without looking much.
