Turning to face his brother's body, Sam searched for any sign of his sibling in the demon that had used his body as a skin. He wondered if this is how Dean felt; scared, and angry, though words could not describe how horrible it was seeing someone he cared so much about being treated like nothing more than a puppet. Looking at Jo, he saw that her eyes had been fluttering in and out of conscious and as she moved slightly in his arms, he knew she'd been fighting to stay awake, despite what her body position had told him earlier.
As he placed her on the floor, Sam turned to Dean; a look of fury were in Sam's eyes. How dare the demon break the tattoo's power and enter itself into his brother's body. He didn't even feel like talking to it; just exorcise the thing before it caused anymore distress. "Silentium maledicte," Sam speaks in latin. Words, he knows, that will harm the demon in an effective way. "How'd you do it?" He speaks, regarding the fact that this demon miraculously possessed his brother.
