He watched as Faith struggled against the door for a moment longer, Sam's concerns lifting from their current situation, for a moment, to focus on the injury that Faith had gotten from out when they had taken on the vampires. That didn't look so good. Not at all. His jaw tightened and he eyed her shoulder warily for a long while before he turned back, fingers raking anxiously through his hair. They were locked in and, for all he knew, she could be very well going after Dean or Dad or Mom or Ben or Ruby - anyone right now. Faith was hurt, they were screwed, his family was in danger. What the hell was he supposed to do?
He took the jacket and from her and tossed it onto the floor. He definitely didn't want that back. Room was already pretty warm. Rolling up the sleeves of his hoodie up the the elbow, Sam returned to Faith's side and quietly placed a hand on her shoulder. He wasn't feeling entirely right at the moment, with his head injury keeping him at bay, but he was okay enough to inspect her own wound.
"We need to get that taken care of," he muttered darkly, gently sliding his hand away from her arm. The only way they were gonna do that was if they found a way out. He stepped away from her and moved back to the furnaces. There had to be another way. He had to keep calm. They had to keep looking. "There's gotta be some other way out of here," Sam started, voicing his thoughts out loud. Stay calm, stay calm, stay calm.
