Fright
Dean and Sam walked into the decrepit house, flashlights in hand. Sam frowned and wrinkled his nose as he scanned the entrance. He smelled a musty, sour odor that was probably related to the mess of leaves and rain that washed in the previous night during the storm, but they were looking for a missing person, and he didn't want to think what else that smell could mean.
Dean sighed next to Sam and pulled out his EMF reader, stretched the antenna, and adjusted the dials. "I'll go this way and scan the rooms," he said. "You take that end." Dean nodded across the foyer.
"Okay." Sam pulled out his cell phone and flipped it open. He grimaced as his beam of light found a splatter of blood on the wall but he held up his phone to snap a picture of it.
"Hah!"
Sam yelped and spun around, swinging his flashlight back and forth. He let out his breath when he saw his brother.
Dean chuckled. "Dude, you're too easy."
Sam glared at his brother. "Jerk."
Dean added, "You should be in horror movies."
Sam shook his head. "Whatever." He readjusted the flashlight in his hand and walked across the room.
"'Cause you scream like a freakin' girl…" Dean let out one last snigger and moved to the next room.
"Shut up," Sam called after him.
