Sam started out the warehouse but stopped short. "Cas, I'm not sure what or who is looking for this book but," he handed Cas the gun he had in his waistband. "This has silver bullets in it. If anything breaches the door, shoot first and ask questions later. No matter what this monster is, aim for the head. Even if the silver doesn't kill them, a head shot will bring them down and give you a chance to run. Your job is to protect Charlie and," he looked over at the chained up, red headed witch who he didn't trust 100 %. "Rowena. Just make sure that we get this stuff translated so I can …"
"We know, Samuel! So you can save your brother because that is what you Winchesters do." Rowena said with a sneer as she rattled her chain for effect. He turned to look at her with contempt. "Don't worry, Moose," she continued as she turned back to the book and research set out on the table in front of her. "I will figure out Nadya's codex, translate the Book of the Damned, and we will save your wee brother."
Charlie sat up straighter at her laptop. "UMMM, Witch, I'm here too and I plan on helping find a way to save Dean."
Rowena rolled her eyes and flitted her hand Charlie's way. "Yes, Dear. I'm sure that your little machine will help you play whatever game you are 'into' right now. Now let the grown up work."
Charlie looked at Cas then Sam with fury in her eyes. "Sam…"
Sam threw his hands up as to signal for her just to calm down. "It's ok, Charlie. Just work together for Dean and I'll be back later. Cas is in charge." Sam said to everyone in the room.
"Sam, I don't think I can shoot a gun at anyone, even a monster." Sam just looked at Cas disappointed.
He grabs the gun and hands it to Charlie. He looks her in the eyes. "This gun is loaded." He quickly shows her how to take the safety off and lets her hold it, feeling the weight in her hands. "Now while there are silver bullets in this gun, they don't kill witches or angels." He smirked at her as she put the gun on the table giving him a disappointed look. He gave her a kiss on top of her head as headed towards the exit. "I'll check in with you, Cas." Cas shook his head as he watched Sam leave him with the two captured gingers.
