"Dean," Sam responded with a mixture of exhilaration, relief and surprise.
The good thing was that Sam wasn't alone; he actually knew someone trapped inside this house with him, but the bad thing was that his brother was a victim and unable to get him out. Still, together they could figure a way out of this dilemma, they'd managed situations like these before.
Granted, Sam did like to occasionally dance with his now deceased girlfriend, but he in no means came here to touch up on his moves just for the heck of it. He'd coincidentally ended up in a large area that just so happened to be made for dancing and so did his brother.
Shaking his head and more than likely rolling his eyes, Sam joined his brother. He could be childish and reply back, but this was a serious situation they were in and Sam didn't feel like playing games. Still, it was good that his brother was ever so cheerful; at least one of them was.
