A/N: Possible slight OOC moment but I think after all the crap Dean is going through on top of all the failures and deaths along with Cas 'dying' he finally reached his breaking point eventually.

Though the consistent vomitting had stopped the dizziness still wasn't fun.

Out on a mission with Dean, Arnold plus a newbie was easier than before but now he had to deal with a new problem; nosebleeds.

The first time it was just after a raid had finished the journey back consisted of Cas holding his nose while catching pouring blood, safe to say his driver - Craig - was a bit freaked out. Cas returned with a red stained shirt, Dean wanted answers immediately but Cas wasn't able to give any, the bleeding wasn't stopping for anyone. By the end of it an old rag was ruby red and Cas was drifting in and out of consciousness.

Putting his foot down Dean locked himself away with Cas in the smaller of cabins and the two dealt with Cas' problems together. Cas didn't want to burden Dean any further but the Winchester's foot was down and mind was set, meaning no-one was going to convince Dean of doing anything else.

"I can hear them..." Cas stated once in his sleeping state.

"Who?" Dean questioned.

"The Angels... they... are calling me..."

"Wouldn't the radios be flickering or something?"

"It's gone, it was only for a moment," Cas' eyelids slipped shut before Dean could ask anything else. Sighing he sat down next to Cas as he had stuck himself against the far wall, Dean pulled him in closer and allowed Cas' head to rest on his shoulder, for now the former Angel's energy was spent, all gone from the excessive blood loss. Cas had snuck in some painkillers before 'Lockdown' - as Cas had put it once while arguing with the Winchester - was set in place to deal with it and though they did make him drowsy from time to time and it was beginning to worry Dean more than it should that Cas was relying on pain medication to power through the day but he wasn't going to babysit Cas when Lucifer was still out there and the Colt needed to be found.

"Talk to me, Cas. What's going on in that head of yours," Dean spoke out loud knowing he wouldn't get a response.

For a moment Dean was delighted Cas was asleep, the consistent breathing allowed Dean to relax. In a pure moment of fear he pulled in Cas' forehead and laid a quick kiss to it, it didn't mean anything, Dean would deny it to his dying breathe that he didn't have feelings for Cas, he just simply cared for his best friend too much to see him suffer alone. That was the whole point of this, keeping Cas under his nose day and night, he figured he was undermining his 'no babysitting Cas' rule but as Dean usually put it after Cas was cleaned up "You can never do anything the easy way, can you Cas?"

Dean turned his head, pulling a face because Cas wasn't talking to him,

"Cas. What happened to you? First the coat was lost, the pills, now... you're almost Human. Bobby's gone, Sam's gone too and I don't exactly give a rat's ass about them out there, maybe I could bat an eye at Chuck but you..." Dean cleared his throat, "If you go... I don't know how long I'd stay sane enough not to blow my own brains out. I'd rather have you here than buried six feet under or become a Croat. Others I could shoot down but-"

Dean had to stop, he was rambling and he was aware people could sometimes hear him when he ranted away. He was aware for the first time in a long time he was becoming emotional and could feel moisture over his dull green eyes

"Don't go anywhere Cas. I don't care what you do; bang everyone you meet, drink yourself stupid or just flat out stop talking but..." Dean sighed heavily "Don't leave... without me right behind you. Is that clear?"

Dean had to shove the lump in his throat down. Cas' head lulled a little as a response, Dean held out hope that Cas has heard something.

"Sure thing, Dean"

The Winchester wasn't sure if he actually heard anything, Cas pulled himself closer to Dean and squeezed Dean's calloused hand.

"I won't be going away anytime soon. Not unless our Fearless Leader needs me to" Cas didn't open his eyes but gave a lop-sided smile.

Dean didn't respond.

"I would return your gesture of affection but I think I'd miss" Cas joked

"Go to sleep, Cas" Dean shot back. Both smiling for a change as Cas drifted off again. Dean knew it was due to finally talking to his friend again and maybe something could happen between them in the future but right now their mission to find and kill Lucifer was priority one.

Extra Note: I've brought up dizziness and headaches before but not gone into detail yet

If anyone wants to see it please R & R as I would like to know if people are interested in reading this.

Some of these may not be in chronological order but all take place before 5x04

I might do a Spin-Off AU where Cas wasn't told to go with the others as the distraction as Past Dean had gotten through to his future self. Future Dean and Cas survive though not unharmed.
