The sudden explosion and sounds that Dean could hear caused him to jump and look up from what he was doing. How the hell? He thought that everyone lost their powers in this place, otherwise he and Cas would never be able to die. Though, Cas was still nowhere to be found, so that remained to be seen.

He saw the silhouette, and immediately he grabbed a rock and his knife, and stood up. He had no idea who, or what, that thing was, and now came the possibility of him dying so soon. Great.
