Sam and Dean broke inside the house which was the crime scene to check out what was going on.

Nothing seemed unusual enough to prove anything supernatural was going on. That was until something exploded and slammed the brothers against the wall.

"You okay?" Dean asked, helping Sam up on his feet.

"Yeah..." Sam replied, running a hand through his hair to get it off his face. "You?"

"I'm good." Dean nodded, looking around.

"The hell was that thing?" Sam asked.

Dean scoffed. "Hell if I know."
