Sam and Dean, along with their younger half-brother Adam, walked cautiously into the abandoned looking house. The three were investigating the mysterious claims of people disappearing from the house. The brothers were Hunters, people who went about, killing monsters, saving people. After recently saving their half-brother from a ghoul, they reluctantly allowed the blond to come with them. Dean, the oldest at 30, walked in first, gun drawn.
"It's safe." he told his two younger brothers. Sam, at 26 and the tallest, walked in behind his brother, making sure their 19 year old brother got in safely. Dean turned to his two brothers.
"Alright, be on the look out. Everyone who's said to come here has disappeared. I for one don't want to be on that list." he said.
"Does that mean we split up?" Adam asked. Sam clapped his brother on the shoulder.
"Yeah, but you're going to be sticking with me."
"You guys know I'm old enough to take care of myself right?" Adam asked. Dean gave him a solid look.
"Yes, but we don't know what's causing the disappearances. Better safe than sorry." Dean tossed a pocket knife to his half-brother and turned to Sam. "Make sure he doesn't do anything stupid."
"Got it."
With that, the brothers split up. Dean walked down the hallway, heading up the large staircase while Sam and Adam walked around the bottom floor. Unknown to the three investigators, the caretaker was watching them through his cameras. He particularly stared at one of them, touching the screen as it got a close up. He'd need to take care of the other two first to be reunited with, what the delusional caretaker believed, to be his long dead son.
