Chapter 1 - Team free will hunting

"Cas, get your feathery butt down here!" Dean cried looking skyward.

"Dean!" Sam admonished, "You really shouldn't call an angel of the lord like that!"

"Shut up Sammy, he doesn't mind it!" Dean replied giving Sam a mischievous wink

"Who doesn't mind what?" Came the deep gravelly voice from just behind Sam, causing the large man to squeal like a girl and jump about three feet in the air.

"Shit Cas! Don't sneak up on me!" Sam shouted holding his chest dramatically.

"But you requested my presence…how is that sneaking up on you?" Castiel dead panned, confusion showing in his bright blue eyes.

"Yeah Sammy, don't shout at the angel of the lord!" Dean said in an indignant voice causing Sam to pull out the mother of all bitchfaces, which in turn caused Dean to chuckle like a naughty school boy.

Castiel knew the chuckle was probably somehow at his expense but he didn't bother delving into it as it was probably something childish, futile and of no real concerned to him.

He instead enquired; "So what do you require from me?" as he wondered towards the table that would no doubt hold the research material for this particular case.

Sam rushed over to the table as well and started to explain; "We had a report from Bobby about a group of demons slowly taking over an entire town about a day's drive from his place, which was only half a day's drive for us so we checked it out. From what we can see they have possessed most people in the local bar and are enticing others in to corrupt them too, it would be good if you could provide some grace filled back-up as we go in to flush them out?"

Sam proceeded to point out the position of the bar and the other relevant points in town on the map.

"I can provide that assistance, especially as my services are not required in heaven at the moment anyway" Castiel sighed.

"Dude, what does that mean – have they kicked you out again?" Dean asked sounding pissed off that they would do that to his friend.

"Not exactly Dean, but even if you had not called I would have shown up presently because they have decided that until further notice I am to be stationed upon earth….protecting you two" Castiel explained in such a way that just made it sound like a huge inconvenience for him.

"Protecting us! Pfft!" Dean exclaimed. "Don't you mean watching us?!"

"Either way I am to remain with you until further notice" Castiel sighed, resigned to his fate.

Sam took pity on the dejected angel "Hey Cas, its OK we'll have a great time…Right Dean…?" Giving his brother a look which indicated he should help to make Castiel feel better.

"Hey yeah of course Cas, we'll show you all that mundane human stuff that interests you so much. Plus…hey strippers...! That'll loosen you up a bit!" Dean replied enthusiastically.

"Dean…." Castiel warned.

"Yeah yeah I know, I should show you some respect…but dude just think of the fun we can have as well!" Dean answered giving Castiel as suggestive wink.

Castiel just sighed again and sat himself stiffly in the chair next to the desk where he proceeded to look wistfully out window.

"Anyway before...all that, we need to clear out this demon problem first" Sam reminded them both.

Castiel actually looked pleased at that thought and sprung back into action.

So they all climbed into the Impala, after Dean had flatly refuse to be angel zapped anywhere, then made their way into town to tackle the demon problem.

Their plan to wipe out the demons ran smoothly for once, Dean and Sam performing the demon extraction ritual as Castiel worked like a very powerful microphone blasting the ritual out over the entire town. Any demons that escaped the extraction were dealt with methodically until the town was completely demon free, if left a little shell shocked.

"Well that was easy!" Dean exclaimed as he cracked open a beer once they had got back to the hotel room.

"Yeah, real easy!" Sam sighed as he bandaged his arm up that had been slashed during a particularly difficult scuffle.

"So what do we do now?" Castiel questioned from where he was standing looking extremely uncomfortable by the door.

"Now we sleep dude!" Dean yawned and stretched. "Watch some TV or something just don't disturb us man...we need our beauty sleep...Sammy especially!"

"Shut it Dean!" Sam replied, not his usual witty response but he found he was feeling really drained all of a sudden as well.

Both men stripped down to their boxers and crawled under the covers, before long they were fast asleep and snoring abundantly, leaving a very bored Castiel sitting uneasily on the sofa in the dim room.

Castiel tried to do as Dean had suggested and watch some TV but everything confused him and without one of the brothers awake to explain why the naked women were talking into mobile phones and shaking their behinds into the Camera he soon got annoyed with that distraction so he turned the TV off.

He sat in silent contemplation for a while before some noises in one of the beds behind him caused him to jump. It was Sam; he sounded extremely distressed and was whispering out little pleas of help.

Castiel was at a loss as to what he should do; Dean has specifically said not to disturb them, which he took to mean that he couldn't wake them. Perhaps he could intercept Sam's nightmare and sooth it for him instead.

So he reached for his grace and used it to delve into Sam's dream.

"No please Maddie...no!" Sam was crying as a petite woman with long brown hair was ripping another man to shreds in front of him. Castiel could tell from Sam's memories that this woman was someone who he had felt affection for once. From what Castiel could make out the women had been turned into some sort of shape-shifter or Werewolf and was now on a bloody rampage.

Sam felt both responsible and helpless, it was very disconcerting for Castiel to see the usually fearless hunter in such a weak position.

Castiel kept himself hidden in the shadows of Sam's nightmare, just observing for now until he could find a way to help ease Sam's suffering.

'It is astonishing how vivid the nightmare is, it truly is amazing what the brain can conjure up' Castiel thought taking in every detail that Sam's mind had managed to produce in its sleep state.

'I wonder if it is just Sam that dreams so vividly, because of his higher IQ or if perhaps it is usual for all humans...even Dean?' He pondered for a moment before suddenly Sam nightmare began to worsen.

Sam was now grappling with the werewolf/women, even though he truly didn't want to. Apparently he knew he had to kill her but it hurt him immensely to do so. Castiel chose this moment to alter the nightmare so that the women took hold of Sam's gun and instead of Sam having to kill her she turned away and shot herself in the head.

Waves of confusion and relief came from Sam, sure there was still sadness there but at least he had comfort in the knowledge that she wouldn't hurt anyone else, also that he hadn't been the one to kill her. Sam stood staring at the motionless women on the floor for quite some time, Castiel realised that he was likely paying his respects and saying his goodbye meaning that he could have some kind of closure over this horrible event.

Suddenly Sam's dream altered again and turned into a version of him running happily around a field with a large sandy coloured dog, he looked young, carefree and happy. Castiel watched the younger version of the hunter running, jumping and playing catch with his canine companion for quite some time just revelling in the joy that was radiating from the dream. Eventually Castiel felt happy that his work here was done so he willed himself away from Sam's minds and back into a conscious state in his own vessel.

Although he was feeling pretty pleased with himself, he knew he really shouldn't meddle with human's minds. Surely it was ok if he was assisting them though, plus it was also a good way to learn more about his charges which could be beneficial to everyone.

Castiel sat on the sofa staring blankly at the wall in front of him, but every so often his eyes would drift to the heap of covers on the bed behind him that was Dean Winchester.

He was torn, he really wanted to see if Dean dreamed as vividly as Sam did, he also wanted to see what Dean dreamed about because the man was such an enigma to him. He knew that the older Winchester would be very mad at him if he found out, he had an issue about personal space and Castiel was pretty sure being inside his mind would count as invading his personal space.

He sat motionless for a while longer looking forward, but again his eyes kept drifting back over to the older hunter. Eventually he decided to give into his curiosity, he would just have to make sure that he wasn't found out.

Castiel was confused as to what he was seeing first of all, Dean seemed to be searching for something really important in a very old house with many doors along a long dark corridor. He stood back quietly as Dean kept walking from door to door in a large house, each time he looked into another room he seemed to be getting more and more frustrated.

"Oh for fucks sake!" He cried as he stormed out of yet another seemingly empty room shaking his head.

'What could he be searching for?' Castiel pondered 'Perhaps he is looking for his father or his brother...both of them being things that he had lost in that past and had been forced to seek out, maybe that is playing on the hunters mind?'

When Dean opened another door and peered inside he cried out in relief "Finally!" So Castiel rushed forward to see what it was he had found, although still keeping himself hidden in the shadows.

Dean was standing in the middle of a bathroom looking at a toilet; he looked confused for a second as he walked over to read the note hung over the closed lid "Out Of Order" the note read.

"Oh Man you have got to be kidding me!" Dean cried, Castiel could feel he was getting really desperate and angry now. Castiel didn't understand the man's annoyance, also why he was searching for a toilet?

All of a sudden Castiel was thrown back into his own vessel as Dean startled awake.

"Hmph!...oh man!" Dean grumbled as he got up and shuffled into the bathroom to relieve himself.

'Ahhh I understand, he needed to use the facilities and that was reflected in his dreams!' Castiel thought.

He sat watching the bathroom door waiting for Dean to walk back out. He heard the toilet flush and the water run for a second before Dean stumbled out of the door and headed back to bed.

Dean stopped halfway between the bathroom and his bed, muscles tensing, his head whipped round, his green eyes widened and suddenly focused on Castiel.

"Shit dude I forgot you were here...! You know that's creepy right...watching people in the dark?!" Dean snapped at Castiel.

Without waiting for a reply he stalked back over to his bed and threw himself under the covers grumbling the whole time about 'creepy ass staring angels'

Before long Castiel heard Dean's breathing slow down indicating that the hunter was fast asleep, he battled with himself about if he should try again. He decided that he should have another look because Dean's dreams had been compromised by his need to relieve himself in the last dream so it wasn't a true depiction of what this particular Winchester could dream.

He reached for his grace and yet again stole his way into his friend head.

He was not prepared for what he saw, it looked like himself but many many different versions of himself all standing or sitting in various poses, but all staring at Dean. Dean was happily going on about his daily life, eating pie and drinking beer, but whatever he did was followed intently by the bright blue watchful eyes the Castiel's. Dean didn't seem to mind; in fact he seemed strangely comforted by the watchful Castiel's.

Castiel was so freaked out by this that he forced himself to leave Dean's head immediately. He felt ashamed of himself for prying and more confused than ever. He sat contemplating what he had seen for the rest of the night.

The next morning Sam got up early and went to fetch coffee. He nodded towards the angel who was sat looking confused on the couch. When he returned Dean was still asleep and Castiel was still looking confused. Sam rolled his eyes and went to wake his brother up.

He put Deans Coffee down on the table next to the snoring man's head.

"Dean...rise and shine!" He called earning a grunt from his brother.

"Dean…come on princess open those eyes" Sam sang cheerfully knowing it would annoy the hell out of his brother.

"What's up with you? Why so cheerful?" Dean grumbled prying open one eye.

"Don't know? Just feel good and slept really well!" Sam smiled happily at his grumpy brother.

"Well bully for you! I slept like shit and I don't feel good!" Dean replied glaring up at his brother.

Castiel jumped at this and turned to stare at Dean. Dean gasped and stared back, feeling like he was being pulled back into that bizarre dream again. He mentally kicked himself and snapped;

"Take a fucking picture Cas, it'll last longer!"

Castiel quickly averted his gaze and hung his head in shame, he knew that Dean didn't mean the words and they were just one of his expressions that he used when Castiel stared at him. Still it shamed Castiel now that he knew that his staring affected Dean enough for it to have a prominent place in one of his dreams.

He didn't mean to stare, he just found his assigned human extremely interesting. He had never encountered anyone like Dean Winchester before and found almost everything he did absolutely fascinating. He decided that he would not look at his human charge if he could help it and he would definitely not be looking into his dreams anymore...no matter how tempting it may be.
