"That seemed a little too perfect," Sam said. "Every bit of information she gave us. It's almost like…"

"Like it's history repeating itself," Dean said, turning his laptop screen around.

Sam stared at the screen. "What's this?" he asked.

"It's proof that I'm a genius," he said. "About 50 years ago, there was this lady. Her name was Gwen Caris."

"What about her?" Sam asked.

Dean rolled his eyes. "She too lived in Salinas, and she too witnessed something horrific. Apparently, her husband had murdered someone after forced entry, but there was no proof. Some people kidnapped her, and took her to a house. A house, that now holds the Johnson family."

Dean paused for a dramatic effect and continued. "They tortured her," he said. "Asking her for the truth. She had seen the crime with her own two eyes, but she loved her sweet Darrell so much, she didn't tell anybody what happened. They eventually killed her, and a week later, his wrong-doings came out to the world, after they proved the case."

Sam now realized what Dean was saying.

"In both cases, the wife had seen something horrifying, but chose to protect her husband, and keep his crimes a secret," he said. After a long pause, he asked, "But how does that relate to the way their husbands died? I get the head-shot, but the not-so-heart attack?"

"You didn't let me finish," Dean said. "A few days after he was taken to jail, he was found with multiple stab wounds all over his body. His clothes were intact though."

They thought for a long time, and Sam finally burst up.

"The wives," he said. "The husbands died in a way similar to what the wives witnessed. Leila's aunt saw him shoot someone, so when the ghost possessed her, she shot him. Leila's mom however, felt like she metaphorically died when she caught him cheating, so that's what she did."

"Alright, so what now?" Dean asked. "The wives got their revenge. Does ghosty go bye bye?"

Sam considered this for a second. "Not quite," he said. "Remember that thing with Luke and Leila? It seemed like she had something against him."

"Shit," Dean said. "Let's go."

…..

Dean rang the doorbell and knocked on the door repeatedly. A weak and bleeding Leila opened the door. Luckily, Sam caught her before she collapsed.

"Are you bleeding ectoplasm?" Sam asked, sitting her down on a chair.

"Oh," she said. "That's what it is. I thought I was going crazy."

"Leila," Dean said. "What happened with you and Luke?"

She held her side and cringed. "How is that even important right now?" she said through gritted teeth.

"It just is," he said. "Sam, what's happening to her?"

"Gwen's spirit, it was tortured. She can't hold long in here. We need to get it out or else her wounds will kill Leila," Sam said.

"That's reassuring," Leila said. "How long do I have for this ghost thing before I die?"

"Usually a few hours," Sam said.

"Great," she said taking a deep breath in. "A few weeks ago, I was studying with Luke, and out of nowhere, he kind of leaned forward and kissed me. After that, he just ran off. When I found him, he said it didn't mean anything to him, and he was just confused. He begged me not to tell anyone, and then we were 'just friends' after that. Her breath grew quick and short.

Dean carried Leila upstairs to her room. Luckily, no one else was at home. He placed her on her bed next to the window, and said, "Look. Sam and I will be gone for half an hour. We're gonna go smite this son of a bitch, and you'll be ok. Just, in the meantime, stay here. I trust you." He kissed the top of her forehead, and grabbed her phone from the table.

He walked out of her room and gave Sam the phone. "Program this so we know when she leaves," he said.

"You don't trust her?" Sam asked.

"Hell no," Dean said. "Not like this."

He walked back in and put the phone in her pocket.

Without saying another word, he left the room and drove off to the graveyard.
