This is the product of a rather long conversation with the wonderful Bobadoo yesterday, who mentioned wanting some Sick!Cas. And that sprung an idea into my head, and won't leave me alone. This was the result!

This takes place during Season 5 sometime after Castiel becomes human, and before they kill Pestilence.

Umm... no warnings really. I guess some Pre-Slash if you look for it.

ENJOY!

Dean was sitting at Bobby's table, polishing his beloved handgun, when a sight he thought he would never see came stumbling in through the backdoor, and proceeded to vomit his stomach contents all over Dean's shoes.

"Jesus Christ Cas!" Dean shouted, jumping to his feet. The now human angel looked up at him blearily, face pale and shining with a thin sheen of sweat.

"Don't feel good," Castiel mumbled, before throwing up again, this time on Bobby's kitchen floor. For a moment Dean was thankful that Bobby and Sam had gone into town for a supply run, so at least he can get the mess cleaned up before they got back, but it was immediately replaced by concern for his friend. Switching in his 'Big Brother' mode, he gently, placed a hand under Castiel's arm, and led him into the bathroom.

"It's alright, Cas," Dean told him, positioning the angel in front of the toilet. "I'll be right back. Try to get it in the bowl, alright?" Castiel grunted his response, and Dean left to clean the sick up off the floor.

Grimacing, Dean kicked off his shoes, and wiped them off the best he could before putting them outside. He kept an ear out for Cas in case he needed anymore help, and began to mop up Bobby's floor. The work didn't require much of Dean's attention, and it let his mind wander.

Pestilence was still roaming the Earth, and Dean would be lying if he said the thought that the Horseman had something to due with his friend's illness hadn't crossed his mind. But a small part of his brain was arguing that if it was indeed Pestilence's work, then Cas would be doing more then just puking his guts out. Therefore, the logic continued, Cas had just gotten some sort of stomach bug. His immune system was weaker now without his angel mojo.

Nodding to himself, Dean finished cleaning up, and headed back into the bathroom to check on Castiel.

"How you doing?" he asked, leaning up against the sink. Castiel glanced over at him, eyes fever bright.

"My head is throbbing, my throat is raw, and my stomach feels like it is trying to escape my body," Castiel explained harshly, "So not good." Dean raised an eyebrow. Obviously, being sick did not do wonders for Castiel's temperament.

"Are you gonna puke again?" Dean asked him. After a moment's thought, Castiel closed his eyes, and shook his head, wincing a little at the motion. "Good. Now let's get you into bed." Dean reached down to help Castiel up, his hand touching bare skin briefly.

"What is it?" Castiel asked when Dean froze.

"You're burning up," Dean told him, voice carefully neutral, hand pressed against the angel's forehead to check for fever. "Damn Cas. How long have you been sick for?"

"A few days?" he offered, not really sure when he had first been feeling poorly. Dean nodded once, and began to lead Castiel to the spare room that had become the angel's bedroom.

"Try and sleep, alright?" Dean asked quietly when Castiel was situated on his bed, "I'll be back in a minute."

True to his word, the hunter returned, carrying a bucket that he placed next to Castiel's head. The angel was already asleep, and Dean chuckled wearily, wishing he could do the same.

He stood there for a few minutes until he heard the familiar rumble of Bobby's truck, and the front door opening and closing.

"Dean?" Sam called from the kitchen.

"Down in a moment, Sammy!" Dean told him. He glanced back once more at his friend's sleeping form, looking peaceful for the first time in a very long while. With a sigh, Dean trudged back down the steps, but not before shutting Castiel's door with a soft click.

I intended this to be a oneshot, but what do you guys think? Should I continue?

Please review! They make the world go round!
