The minute the demon went for Sam, Dean set a shot straight at the demon in front of him. Not having much time to properly shoot it or his brother a look before two other demons barreled towards him. Two he could handle. Shooting at one and jabbing his elbow into another. His managed to see his brother, both brothers obviously and deliberately separated by the demons. A few attempting to rush at Dean. His preoccupation with Sam ended up with a doubled-over Dean; nevertheless, he managed to right himself and regain an upper hand before a demon could punch him in the face. Again.
However, when straightened, he noticed that he had lost sight of his brother. He couldn't find Sam anywhere.
He began to make his way to where he had last seen his brother. Getting a few demons good with holy water on the faces. Not even enjoying the screams with even the smallest hint of satisfaction. His focus on getting out of this alive and finding Sam. It felt as if more demons had appeared but their numbers had nothing on Dean Winchester's determination.
He spotted ... what seemed to be Sam. "Sam!" He called out. What the fuck was he - the sight that Dean stumbled upon caused him to still completely. Just staring as his brother drunk from the demon's neck.
Disgust was immediate and low but it was overshadowed by shocked and disbelief as Dean just stared at the back of his brother's head. "Sam." He said again, lowly, less sharply but no less urgently. Emotion coloring his tone.
