Sam Winchester slammed the motel room door shut behind him. He threw his bag down onto the bed and collapsed next to it. He flipped his phone open and checked his text messages.

Hey Sammy, when you get this give me a call.

Sammy?

Okay I'd really appreciate some sign of life from you, give me a call.

Sam. Call me.

Sam sighed. He pressed the speed dial button for his brother and held the phone to his ear, bracing himself for a telling off.

"Hey, sorry I can't talk right now, leave a message." Dean's voice message reeled off. That was odd. Sam frowned and punched out a quick message to his older brother.

What's up? Why didn't you answer? Call me back.

He lay back down on the bed and closed his eyes, hoping to get a couple of hours of sleep. He was barely drifting off when his phone started bleeping loudly. Groaning, he rolled over and pressed some random buttons to light up the screen. Dean's name filled up the screen. Sam pressed the answer button and held the phone up to his ear, gingerly.

"Where are you?" Dean demanded.

"Indiana. Why? What's up?" Sam asked, confused.

"I've just got my next target and guess who it is Sammy." Dean answered humourlessly.

"Me." Sam groaned. "Why? I've not done anything for months Dean."

"I don't know, I don't get told things like that and anyway, that's not the worst of it. I've got a partner on this one. Clearly they think you are too dangerous for me to handle." Dean complained.

"Or maybe someone high up does actually know who you are and knows that I am your brother. Maybe they don't trust you to get this done. Anyway, who's the guy?"

"He's called Castiel Novak. Also known as Agent Wings." Dean said in a sarcastically cheerful voice. "On the upside, he doesn't seem to know who I am. Just my first name and my code name."

"Well, that's something. Try to keep it that way Dean." Sam said.

"Yeah, I know." Dean said, rolling his eyes. "Gotta go, Mr. Novak is almost back."

"Oh, Dean, one more thing before you go. Try not to get too attached to this Castiel guy. Chances are, we're going to have to kill him before he kills me." Sam said, flatly and without any traces of emotion. Dean sighed.

"Yeah, sure, no problem." He said hanging up.

Sam rolled back onto his back. He rubbed his face with his hand, pinching the bridge of his nose. 'Might as well try and sleep. This week is going to be crazy.' He thought.

Sam had first gotten onto Hilters radar in a bad way when he had blown into a town, practically decimated it and then accidently left a clue behind. Being a hunter, he had his reasons; namely, a crew of about fifty demons. But when you are faced with a top-secret government organisation that knows nothing about demons hearing about a guy that destroyed a whole town, there isn't much you can do but run. Sam had been forced to take out every agent the company had sent before, one day, he got off their list. Now, for some reason, he was back on it. And this time, they had sent his brother.

After he hung up with Dean he had tried to make himself sleep but his mind repeatedly fixated on the idea of his brother hunting him down. Eventually Sam gave up and opened up his laptop. Logging into Dean's personal Hilters page (Dean had told him how) he began to sift through the piles of information and data. Nothing on this Castiel, or any Novak at all. Not even a mention of Wings. He sat there for a good half-hour attempting to hack into the site. He wasn't good enough; he needed Charlie.

Slamming the laptop shut he pulled out his phone and sent Dean a message.

Where are you?

He then began to pack all of his things into his bag and then proceeded to check his guns were in working order and his knives were sharp.

"Wait here, just going to get a drink." Dean said to Castiel, opening the car door. As soon as he got out he pulled out his phone and began to text Sam.

We're in Colorado but apparently Hilters know where you are. Cas is directing me straight to Indiana. Clear out Sam.

Barely seconds passed before a reply came; 'Cas'? Hmm... Sounds like you're getting attached. Okay, I'll leave tonight. I'll go to Georgia or something.

Sounds good. Shoving his phone into his pocket he pushed the door to the Gas Station open. He nodded to the man behind the counter and grabbed a couple of beers and a few diet cokes. He paid and left.

"Who were you texting?" Cas demanded as soon as Dean got back into the car.

"None of your business." Dean retorted.

"It is if it threatens the mission." Cas snapped.

"Chill, it's just my kid brother. Adam." Dean replied, making up a name on the spot. "He was wondering where I've been the past month and I was just telling him that I'm working."

Cas looked suspicious but let it slide. "Okay, well I got an update from Hilters while you were in there. Sam Winchester was last seen in Indiana so that's where we are going. Any questions?"

Dean raised his eyebrow. "No?"

"Good." Cas said. "Let's go."

Dean put his foot down on the pedal and kept his eyes on the road, fully aware of the other man's eyes on him.
