"In the last month, there have been at least a dozen cases of women getting pregnant through unexpected circumstances in this town," Jo glanced up at Charlie's announcement as she watched the redhead who was hunched over her laptop, deep in research.

"Where'd you find that?" Jo asked as she got up from her own laptop and moved over to peer over Charlie's shoulder. "And what about further than that?"

"I broke into the records of the local medical clinic," Charlie explained. "It's a small town, so there's only one. But take a look. Many of these women had been on various forms of birth control; three of them had had their tubes tied."

"Well, I found something," Jo responded as she brought her own laptop over. The two of them had been pouring over records and reports for hours now, and the more they learned, it seemed like the more unanswered questions there were.

Jo had thrown herself into this case. She had no idea whether or not Sam or Dean were onto the strange happenings in this town, because, she had been avoiding Dean. She was all too happy to take on a possible hunt if it meant being able to put off having to discuss her vampire problem- or her own pregnancy, for that matter- with him.

"What did you find?" Charlie's voice brought Jo out of her thoughts, and she blinked, concentrating on her own findings.

"Right, sorry," she said. "Apparently, a new fertility clinic opened up in town," she explained. "It seems like this town has an unusual rate of infertility, which seems to have been alleviated by the arrival of a Doctor Ainsworth about a month ago. And then, just like that, even women who weren't planning to get pregnant got knocked up."

"We've only been in town for a month," Charlie said. "And so has this chick, it seems like. Coincidence, maybe?"

"Yeah, well, maybe except her previous located was Kansas," Jo informed her grimly. "She claims to be a traveling doctor who worked in fertility clinics all over the country, and her last stop was a fertility clinic less than 100 miles away from where Sam and Dean's old bunker was. And she was there for about six months."

"Ainsworth, huh?" Charlie murmured contemplatively as she stroked her chin a little. Jo smirked at the small gesture. "Think we should have a look?"

"Yeah," Jo nodded eagerly. "Her presence might explain what's up with Hannah, I mean she got pregnant before we got here and then as soon as we got here, it's like it's something in the water."

"Speaking of that, did you talk to Eileen?" Charlie asked. Jo sighed and sunk into a seat beside her.

"Not yet," she said. "Don't quite know how to tackle that question. Hey Eileen, how's it going, hey, by the way, have you screwed Sam lately?"

"Hey," as if on cue, the brunette's voice had both women glancing up from their seats to the entryway where Eileen stood watching them. Jo frowned as she looked her friend over, trying to discern if there could be anything a little off about her. She couldn't help but notice the preoccupied, distant look on Eileen's face.

"Hey," Charlie greeted before Jo could as Eileen came forward and slumped into a seat at the table, slumping over a bit. There was a tension in the air as Charlie and Jo both studied the woman as she stared at her hands, strands of hair obscuring her face.

Jo waited for Eileen to look at them, knowing she couldn't hear them. When she finally did lift her gaze, Jo couldn't miss the glistening in her red-rimmed eyes, a telltale sign that she had been crying recently.

"Let me guess," Jo began with a sigh. "Aunt Flo didn't pay a visit this month?" Eileen raised a brow in confusion.

"How'd you know?" she asked, looking back and forth between them. Jo and Charlie exchanged glances.

"Well, let's just say we're on the trail of the possible culprit," Charlie replied as she pivoted her laptop around to show Eileen. There was a slight pause as Eileen read the medical records displayed there and the profile of Doctor Ainsworth.

"A doctor at a fertility clinic?" Eileen commented as she read turned her focus back to her friends. "I don't get it. I didn't go to some fertility clinic."

"Neither did I," Jo replied. "And neither did Hannah. But regardless, this bitch is meddling in things she shouldn't be."

Eileen took in a long exasperated breath. "Is she a witch or something? Why is she doing it?"

"We're going to head over to find out," Jo explained as she glanced at a few of her own records. "Whatever she is, I'm willing to bet she isn't human, and that's enough for me."

Jo realized how shallow her own words sounded the moment she uttered them. Not human. As a hunter, it was her job to rid the world of monsters, and Ainsworth might be a monster, but… so was Jo. Was she justified in being part of this hunt? It seemed that she was on the other side of the fence now, and she didn't know how she'd rationalize it. After all, was Ainsworth even bad? Maybe she had good intentions. Perhaps she didn't realize that whatever she was doing was affecting everywhere she went.

"Uh well, that's… that's something I need to tell you two," Eileen said as she sat back in her seat. "You know what happened a month ago… when Sam and Gabriel found me out in the forest right after that werewolf attack…"

"Yeah," Charlie said as Jo recalled the whole ordeal.

"Jo, Charlie… I'm the werewolf," Eileen blurted out, swallowing audibly as a look of worry crossed her eyes. "I could have killed Claire… I had no memory of it, but when Sam told me everything, and the way I was feeling…"

"How were you feeling?" Jo asked gently, mentally encouraging her friend. She found that learning this news gave her a profound sense of relief, though she was concerned for Eileen. At least they were both in this together.

"I know it's crazy, but I felt like I was going through some sort of crazy Vulcan pon far," Eileen replied. "I mean, it's like my libido was in hyperdrive. And it lasted a few days after the full moon. I mean, Sam didn't complain once I got checked out at the hospital and all and if I had just stopped with him…"

"Wait… who else?" Charlie put in. "I mean no one's going to judge or anything, Eileen, you can tell us."

"Gabriel," Eileen stammered out in a breathy sigh. "Sam doesn't know either. I don't know how to tell him. I just… I felt out of my mind. Like I was watching myself from the sideline."

"So uh… I hate to bring this up, but… do you know which one of them the father is?" Charlie asked. At that, Eileen burst into tears. Jo sighed, scooted her chair over, and pulled the woman into her arms while Charlie moved to her other side, rubbing her back.

As Jo held Eileen against her, she glanced over at Charlie. "I've never heard of werewolves having some sort of heat thing," she commented. "But then, no one's ever bothered to take some field notes about their society, you know? There's nothing in the lore that says anything about this being a symptom."

"Maybe it's related to what we're investigating," Charlie suggested with a thoughtful shrug. "We should find out for sure, and we'll start with Ainsworth."

Jo nodded as she held the weeping Eileen. All she could think about was just when it seemed like they were on the trail of some answers; they were confronted with more questions. All she knew was that it seemed like every single one of them was becoming more and more involved in something that none of them had any idea what the outcome would be. And she hated Ainsworth. She hated that she and her friends had become victims in whatever scheme was being cooked up. After all, a hunter's life was not exactly a place to bring in a child, much less three.
