~Sometimes when all your dreams may have seen better days
And you don't know how or why
But you've lost your way~

It wasn't so much Sam finding Castiel as it was Castiel finding Sam.
Cas had been in hiding for God knows how long, having picked up that there were some angels (more like mercenaries) out for his head. Angels from Raphael's side, to be exact.
They'd threatened him, at first, which didn't frighten him much, as much as he cared for (Cas nearly snorted at that) Dean and even Sam, he was okay with dying. Well, not okay, but.. He could handle it.

The one thing he could not handle, though, was endangering others (especially the Winchester boys) only because of their sheer connection to one another.
So Cas had cut off all contact and ran. He ran everywhere. Leaving enough traces to have the angels chasing him keep on his tail, but far enough away so they wouldn't catch up with him and in turn making sure they were distracted enough not to go after the people who had no part in this war.

And he had thought he'd given them the good run-around when they didn't seem to catch up with him, but it had been too silent, for too long. And Cas couldn't help himself, he grew worried. So for just one second, maybe not even that long, he closed his eyes and just listened. Listened for that familiar voice to make sure he was okay. But what he'd heard was anything but okay. "Castiel.. Please.. Don't leave me to die here.."

~Have no fear when your tears are falling
I will hear your spirit calling
And I swear I'll be there
Come what may~

Cas and Sam practically literally ran into each other. "Cas! Hey! There you are. We were worried sick about you, man. Where the hell have you been? We've been trying to contact you for months.." Sam said, a glint of happiness in his eyes to see his friend alive and well. But he soon changed his tone as Castiel was giving him his stone-cold 'I am the scariest being on this planet right now' look. "Where is Dean?" was all Castiel asked. His blue eyes piercing Sam's, his demeanor stiff but slightly.. twitchy?
Sam raised an eyebrow and looked utterly confused. "We had a disagreement. I went to go look for you and Dean went to track these two rogue angels that have been leaving dead bodies all over town."

Castiel looked furious at this point. "You left him to go deal with angels on his own?!" He thundered out, causing Sam to actually flinch. "Dude, just calm down man.. I'm sure he's fine." Sam stammered, trying to regain his ground, but the look Castiel was giving him was anything but forgiving, or calm for that matter.
"We will need to track him down right now." Castiel ordered. And as they traveled back to the motel Sam and Dean had been staying in (with Castiel's 'woosh' type of travel), Castiel focused in on Dean's being once more, hoping against all hope that there was still anyone left to focus in on.
"Why won't you answer me Cas.. Please.."

~When you have no light to guide you
And no one to walk beside you
I will come to you
Oh, I will come to you~

Though Raphael's angels had been great in their hiding techniques as well as torture methods, what they lacked was a general knowledge of the human race. More specifically, human technology. Dean had had his cellphone on him when they took him. And even though they had taken it and smashed it, it would still prove useful.
Specifically when Sam used an app on his own phone to track the GPS coordinates of the last time Dean's phone bounced off a tower (thank God for great cellphone internet connectivity). And they were able to somewhat pinpoint a location. And after scoping the location online (they probably should send NASA a big thank you for letting Google upload so many top-down pictures of maps), it was fairly easy to figure out where the angels would have taken Dean. And abandoned warehouse, about a mile from the city.

Once they figured out the exact location, Sam had trouble keeping up with Cas, who had grabbed his angel sword and pretty much just stormed out the door, death glare in tow.
Once they reached the location, Castiel stopped Sam before he could even so much as touch the doorknob, let alone open the door. "You stay out here." Castiel commanded. And although with every fiber of his being Sam wanted to argue, the tone in Cas's voice was clear enough. Cas would get the job done. Cas would save Dean. Sam would only be another vulnerable pawn in this wargame and Castiel would not have it. He would not risk losing Sam only to get Dean out with no one to return home to.

Castiel walked around inside as if he owned the place. He felt like an unstoppable force. He made his way straight to the double doors at the end of the hallway, proverbial guns blazing. When he opened the doors and saw Dean, his Dean, lying on what could only be described as a torture table, unmoving and nearly unrecognizable due to the cuts and bruises, he literally roared.
The sound made for quite an impact, because suddenly he had two rogue angels flying at him, but Cas wouldn't take it, not for one second. He had someone to fight for. Someone he would always fight for. So with some luck and a lot of determination, he eventually managed to stake both angels with his angel sword, their bodies dropping down on the floor like sacks of potatoes. And then he made his way to Dean.

When he realized Dean was unresponsive, Castiel finally lowered his own walls. He didn't want to feel, he didn't want to be aware of the state Dean was in, but he knew.. He felt that Dean was still in there, alive and kicking. He just needed to get out of here, and he needed to be healed. So he did the only logical thing his mind could come up with then and there and grabbed a hold of Dean, disappearing before reappearing in the stuffy motel room he'd been in a mere hour earlier with Sam.
Sam.. Castiel sighed and fished the spare cellular phone from his inside trenchcoat pocket and sent a text message to Sam. "Back at the motel. Dean is alive." And then quickly put the phone away again.

Castiel then sat down on the bed next to where Dean was now lying and he couldn't help himself, tracing his index finger gently through Dean's hair. He sighed and then put his hand against Dean's battered cheek and felt the energy flowing from his own body into Dean's. And though the blood on his body remained, and though there were still a couple of cuts and bruises visible, Dean was going to be okay. And even though Castiel felt so lucky to have been able to save Dean, he knew that he himself, would never be okay again. Not when it came to this man.

~When the night is dark and stormy
You won't have to reach out for me
I will come to you
Oh, I will come to you~
