Castiel had just flew into the dirty motel room Sam and Dean had been staying at. He looks around expecting to see both the Winchester boys, but he notices it's just Sam. Sam was asleep on the bed farthest away from the door with his hands tucked under the pillow. Castiel noticed that Dean always liked to choose the bed closest to the door as to protect Sam from and intruders. Cas slowly looked over the younger Winchester's silhouette. While Sam is awake and standing he towers over Cas, but seeing him asleep and laying down he almost seems like a small boy, peaceful instead of always alert and stiff. Cas sits on the opposite bed, watching and waiting for either Dean to come back or for Sam to wake up. Then Cas notices Sam stir a little and he cocks his head, wondering what has interrupted the younger Winchesters peaceful sleep. Sam whimpers a bit and murmurs something, Cas listens closer and Sam's whimper turns into a moan. Cas narrows his eyes at Sam, is he having what Dean calls a 'Happy Dream', if so about who? Before Cas met the Winchesters he wouldn't have cared what dream Sam was having, but now he feels he needs to know everything, thought and action of the brothers. Then Sam mumbles the name 'Dean' followed by another moan. A small smile crosses the angels face. Cas watches over Sam the rest of the night until Dean arrives in the early morning. When Dean walks into the motel room Cas stands and Dean looks at Cas questioningly.

"Cas, what were you doing?"

"Just watching over Sam."

"Sam's fine. I wouldn't have left him alone if there was something to worry about…" Cas looks down.

"I like watching over you two. Sense I left heaven I felt like I had no purpose anymore, so I made my purpose watching over you Winchesters." Dean sighs and glances over at Sam.

"Well?" Cas looks at Dean confused and Dean rolls his eyes. "How was Sam while I was gone?"

"Oh…He was fine…preaceful" Dean smiles a little and nods. Then Cas continues. "He dreamt about you." Deans smile turns into a smirk.

"Yeah, I bet he did" He smiles proudly remembering how he and Sam had passed their time earlier. This time Dean had let Sam be on top. Usually Dean likes to take control. Cas knew that the Winchesters were…sexually involved but he didn't quite understand the depth in the relationship. He watched Dean closely as he went through his memories of the earlier activities then Dean seemed to snap back into reality. "Was there something else you needed Cas?"

"Yes, I found the location of Crowley." Dean growled hearing the demons name.

"Where?"

"In an abandoned welches factory in a small town called Westfield, NY" Dean nods then hits Sam's foot waking him up. Sam wakes up startled then looks around at Cas and Dean.

"Cas found Crowley, once you're ready we're leaving." Sam quickly gets up and dresses into clean clothing. They Winchesters turn to the angel and he flies them to the abandoned building.

"There are at least five demons outside of the building." The angel says. The Winchesters stealthily take out the demons that were patrolling the perimeter of the building. Cas looks around at the outer walls of the building.

"Cas?" Dean says.

"I can't go in with you" Dean swears under his breath then nods.

"There goes out angel back up. Alright Sammy, lets go." As they go to enter the building Cas stops Sam.

"Cas?" Cas takes Sam's hand and hands him an angel killing blade.

"This works on demons too." Sam looks at Cas and nods. He had felt a small sensation go through his body when Cas had touched him, but right now he will have to ignore it. He smiles a little at Cas.

"Thanks, Cas" Sam follows Dean inside. As soon as they get inside they start wiping out demons as the Winchester tag team. One demon comes up behind Sam and starts choking him. Sam struggles until Dean comes up behind him and stabs him with Rubys knife.

"Thanks, Dean…" Dean looks at Sam and nods then they keep on battling their way through the ware house. Finally they make it to the biggest room where there are a bunch of machines but obviously the demons have made their self at home. Crowley was standing in the middle of the room. Sam and Dean look a bit surprised because it appears that Crowley had been waiting for them. Suddenly Dean panics and turns with Sam to run but in seconds they're surrounded by demons. Dean swears under his breath and stands protectively in front of Sam. Crowley claps.

"It was quite a show you boys put on making your way to me, but I figured when I saw your angel snooping around outside my house that I would see you two soon." Dean growls at Crowley knowing there's nothing they could do, they were outnumbered. Sam stays close to Deans back instinctively looking to him for protection. As Crowley walks towards them a demon rips Sam from Dean's side and it stabs him in the back. Dean watches in horror.

"SAMMY! You son of a bitch!" He has flashbacks of the first time Sam had been killed, stabbed in the back by one of the 'Special Children'. This would be the second time Sam had died under Deans watch. As Dean goes to attack the demon Cas appears and takes the Winchesters quickly back to their hotel room. Both Cas and Sam drop to the ground.

"Damn it!" Dean hurries to Sam's side first and checks his back. Luckily the demon missed Sam's spine. "Cas! Heal him!" Cas stands weakly, the anti-angel symbols had drained most of his power as he rushed into the building to save the boys. He is able to heal Sam enough to save his life but not enough to heal him completely. Cas passes out. Dean rips off Sam's shirt then he patches him up and lays him back on his bed. "Damn it Sammy…" Dean glances over at Cas and sighs, then helps Cas's limp body onto the other bed. He looks over both Cas and Sam. He knows it's his duty to keep Sam safe, how could he have been so reckless?
