Considering the seriousness of what they'd just discovered, the mood in the car back to the house was pretty light. The tension that had started to emerge on the way to town was dormant, and even though they new it would come out and have to be resolved at some point, everyone was quite content to hold off, for now.

Once they got back to the house, Isabel started to make lunch.

"Grilled cheese sandwiches?" She asked the boys as she opened the fridge.

"Perfect" Sam said, sitting down at the kitchen table and unfolding his laptop.

"Need help?" Dean asked, and she fought the urge to faint.

"No, thanks" She said pulling out ingredients

The next half hour passed quietly and uneventfully. Dean gathered all of his and Sam's dirty laundry and dumped it into the hamper in the laundry, before sitting down at the kitchen table and checking his voicemail.

"Anything?" Sam asked.

Dean knew he was talking about their dad "No. All's quiet"

With everything that had happened in the last few days and the tension that was always hovering under the surface between Isabel and them, the last thing either Sam or Dean wanted to do was bring up the topic of their absent father in front of her. It had not escaped their attention that Isabel had not even asked about John. It was obvious that she just flat out did not care in the slightest where he was or if he was OK.

Isabel was quiet while she made lunch, every now and then looking over at the boys. She wanted to clear the air about what had happened earlier that morning, but felt that it wasn't the right time yet. With all the stuff that seemed to be happening, she was beginning to think there would be no right time.

She was hopeful though, especially when Dean walked over and helped her set the table. They all ate silently. Sam still looking at his computer, Dean looking over his dad's diary and Isabel was looking through her appointment book, deliberating on whether she should take some time off this week while Sam and Dean were around or not.

"I think I know what's doing this" Sam said from his seat at the table, his face looking away from the screen to his brother and cousin.

"What you got?" Dean asked moving to stand behind Sam.

"Incubus"

"The band?" Isabel asked as she started clearing the plates.

"No" Sam said slowly "as in the male version of a succubus"

"What are you talking about?" She asked, leaning against the kitchen bench.

"It's essentially a demon" Dean explained "Traditionally they come to women at night, seduce them"

"Traditionally?" She asked.

"Yeah, in folklore, legend. This guy is different though. A less…mythical version" Sam continued "He takes women with him. He keeps them"

"He collects them" Isabel offered.

Sam nodded "That's right. Think about it. They're all healthy, young, pretty girls. He's using them to breed. That's why he keeps them. That's why he got rid off Kelly. It was only because she died"

"Oh my God. Like his own little harem or science experiment" Isabel said, her face paling "That's more disgusting than I originally thought"

"Wait a minute though" Dean interrupted "You said he takes them? There's never bee any sign of struggle. How does he just take them?"

"Incubi are though to be able to come to women as someone they know" Sam explained.

"Shape shifter?" Dean asked thinking of the last time they'd dealt with one of those. He was not in the mood to go through that again.

Sam shook his head "No, I think he makes people think he's someone they know, someone they trust"

"Kinda like hypnosis?" Isabel said "Physically he's still himself?"

"Yeah" Sam said "And he's keeping these girls until they…outlive their usefulness"

"You mean until they die" Isabel said, beginning to understand.

Dean frowned, shaking his head "If there was a demon walking around town snatching women, how come no one's seen anything weird?"

"He must have a human form" Sam said looking through some of his printouts "Maybe he's half human half demon"

"So he looks like a human normally. We're not looking for some freaky looking monster thing?" Isabel asked.

"It's not a big town" Sam said pulling up a map of the county on his screen "It's got to be someone new. Someone who may have moved here recently"

"I could probably find out about that" Isabel offered walking over to where the boys were "I'm in real estate. What would I look for?"

"Single men" Dean suggested "Any who've moved here in the last three months, no more recent than seven weeks"

"Shouldn't be a long list" She said "There are only three agencies in town. I'll get right on it first thing in the morning"

"In the mean time" Sam said, returning to his computer "I'm going to look for anything similar that may have happened in other towns again cross referenced with dead bodies and or girls that may have escaped. See if this thing has done this before"

Sam worked at his computer all day, while Isabel trundled around the house tidying up, doing the laundry and planning the rest of her week. Dean had made himself comfortable on the couch, watching TV for the rest of the day. Sam figured his brother was finally able to unwind after months, or rather, years, of being on the road. He hadn't see Dean so content in a very long time.

He looked at Isabel every now and then as she sat across the table from him, scribbling away on her weekly planner, and smiled to himself again. She too looked happy about them being there, and he wasn't really all that surprised. He knew that the initial reunion wouldn't go smoothly, and he knew that it would take a little while for her to warm up to the fact that her cousins were back in her life. But he also knew that she had missed them terribly, and stubborn as she was, like Dean, she had a good kind heart, like Dean. He knew in his heart that everything would be sorted out before they left for the road again.

Isabel caught Sam staring at her, and she took her reading glasses off, setting them down on the table and looked at Sam with a curious smile on her face.

"What?" She asked.

"Nothing" Sam shook his head and smiled as his eyes returned to the screen before him "It's just that…this…this is nice"

She looked at him strangely "Researching a psychopathic demon rapist is nice?"

"No, I meant…us here. Seeing you after so long. It's nice. I missed you" He said sincerely "Despite the reasons and circumstances, I'm glad we're here"

She took a deep breath and watched him for a minute "Can I be honest with you?" She asked and Sam nodded "I'm glad too"

His smile brightened "I know, I could tell"

She laughed softly "I wasn't so happy at the beginning" She confessed.

"I know, I could tell" Sam repeated.

"But I realise now that I've missed you guys too. I've been living alone for so long now; I've forgotten what it's like to need anyone"

"But you've had boyfriends before right?"

She shook her head and slipped her glasses back on "Never anything serious. No close friends. I have…uh…trust issues"

"Is Jack any different?"

"I don't know yet" she said "I'll push him away soon enough though, just you watch"

"I think we've all been somewhat damaged" He said comfortingly.

"I have to agree with you there" She said "There's a lot of baggage in this family"

"How's the brain trust going?" Dean asked Sam as he stepped into the kitchen.

Sam sighed and picked up the note pad he'd been scribbling on "Found something" He said showing Dean his notes "This has happened before. Girls missing in the space of a few weeks, a couple found dead just like Kelly"

Dean read aloud "Small towns in Arizona, Rhode Island and Oregon"

"Oh God" Isabel said "all over the country"

"Could be more. They are all about a year apart, girls start vanishing for a couple of months, then nothing is heard again. He packs up and moves" Sam said.

"Once they all die?" Isabel asked.

"Or once someone's close to finding them" Dean suggested "what about the…babies?"

"I don't think any of the pregnancies have been successful" Sam said shaking his head "Whatever kind of demon he is, he can impregnate human women, but they can't carry the pregnancy to term"

"And he just keeps trying and trying" Isabel said as her stomach churned "And once he's moved on from here, he'll go somewhere else and try again"

Dean stood up and looked at her, his expression stern "No, he won't"
