What if Dean and Lisa had one of the shape shifter babies?

After talking with the cop, Sam took out his cell phone and called Samuel. "There was another one. This is the fifth one in five states. Parents killed and the baby gone on its six month birthday. No traces of EMF or sulphur in any of the houses. So, it's not a demon or a ghost."

"Do the babies or parents have anything else in common besides being exactly six months old?" Samuel asked. This case was hard for him. He couldn't imagine anything happening to Mary at that age.

"Nothing I can find," Sam said.

"Hey, how old is my great grandson?" Samuel asked, concerned. Of course, he hadn't had any contact with the child and had only seen Dean that one time since he came back, but they were still family.

"You mean Dean's kid?" Sam asked. "I guess it's probably about that age," he said, seeing where Samuel was going with this. Maybe they could use it for bait.

"It?" Samuel asked. He really wondered about Sam sometimes. How could he be his grandson, or more oddly, Mary's son.

"Him," Sam corrected. He needed to watch himself. He knew he wasn't normal, even if he didn't know exactly what was wrong with him.

"Maybe you should go see Dean," Samuel suggested.

"Yeah, OK," Sam said.

"So, why did we have to move?" Ben asked.

"Just a precaution," Dean answered, as he and Lisa were unpacking kitchen stuff.

"Whatever," Ben rolled his eyes. He stood up and headed towards the door.

"Where are you going?" Dean asked, sharply. More sharply than he had intended.

"I'm just going to check out the neighborhood."

What? Was he crazy? Ben didn't know how to protect himself against anything. Dean was torn between wanting to train him to keep himself safe and keeping him far from that life. Everything was so much more simple before that djinn had come for him. "And leave your mother with all this work?" Dean asked to postpone the moment.

Ben rolled his eyes again, but came over to help with the unpacking. Dean couldn't help but smile. Sam might have met his match in the eye rolling department.

The baby monitor alerted them to an awakening upstairs. "Sounds like Sam's hungry," Dean said. When Lisa had found at she was going to have a boy, Dean had asked her if they could name him Samuel John. She agreed. But now, with Sam alive, it seemed a little weird.

"I'll go," Lisa said, leaving Dean and Ben. Ben was really resenting this move and she thought maybe they should talk things out.

When Lisa left the room, Dean's cell phone rang. He checked the display. When he saw Sam's name he was pleasantly surprised. He had told him to keep in touch, but he had been afraid that he wouldn't. It was really hard for hunters and non-hunters to stay connected. Sam had never once called him when he had left for Stanford. Dean had called him once when he had been gone for two years and it was probably the most awkward phone call in the history of phones. He hadn't bothered Sam again until their father had gone missing.

"Hey, Sam," Dean said, picking up.

"Hey, Dean. I need to talk to you," Sam said. This was going to be hard. Dean was going to notice something was different with him.

"What's up?" Dean asked, walking into the other room, away from Ben.

"I'm working this job," Sam began.

"I'm out," Dean said, not wanting to hear anymore about that.

"Yeah, Dean, I know," Sam said. The last thing he wanted was Dean back in the hunt with him, watching him analyzing him. "I'm just a little concerned because something is taking babies on their 6 month birthday and killing the parents. I was just wondering exactly how old your son is?"

"He'll be six months old tomorrow," Dean said as he fell down into the couch behind him. This couldn't be happening.

"Whatever this thing is, it's not taking every single six month old kid, Dean," Sam said, wondering why Dean sounded so worried. After all, he was a hunter and could protect the kid and himself. And if he did happen to lose the kid, he could probably make a new one if he wanted.

"Yeah, I know," Dean said, glad that Sam was trying to make him feel better. "Do you know what it is?"

"No idea. Pretty sure it's not a demon, though. No sulphur at any of the houses." That had actually been Sam's first thought. After all, a demon had come for him a bunch of others on their six month birthdays.

"So, no idea?" Dean asked. It was going to be hard to protect against some unknown. If he knew what it was, he would be able to gear up better.

"No," Sam said. He remembered his idea of using the baby as bait. "Want me to come over?"

"That'd be great," Dean said, relieved. Sam had been hunting this past year. It would be great to have him as backup.

When he hung up with Sam, he wondered how much he should tell Lisa. Lisa came down the stairs with the baby. "Here, Daddy. Sam wants you to change him."

"OK," Dean said. "Hey, Lise."

"Yeah?"

Dean concentrated on the diaper changing for a minute not knowing how to start. "Sam called," he finally said.

"Yeah?" Lisa asked warily. She had been afraid that when Sam had turned up alive last week that Dean would start leaving to go on hunts with him.

"He says something's been stealing babies on their six month birthday."

Lisa looked up sharply at that. This wasn't about Dean wanting to go on a hunt, this was about a hunt coming here. "What are we going to do?"

"Sam's going to come and stay with us a couple of days. Keep watch."

"Good."
