"I believe it may be Gabriel's Horn." Cas looked at Sam briefly.

"Gabriel's Horn? Like, trumpet-horn?"

"Yes. Of a kind."

Sam sighed slightly.

"It's a good thing we handed off that other job," he commented. "Alright, where is this horn, then?"

"Here." Cas pointed to the appropriate town since Dean had a map pulled out. "I will assist as much as I can." Here meaning distract the people so the boys could actually get the Horn without being slammed around overmuch.

"Great," Sam said. "We'll head out in the morning, then." He toed off his shoes, and began to take off his jacket when he paused and looked at Dean. "Hey, Dean... Did you notice anything odd earlier? With the girls, at the diner."

"Odd how? Like our kind of odd?" Dean shrugged. "I dunno, they seem okay to me."

"What do you mean by odd?" Cas turned his attention to Sam at that, because he did (mostly) trust the Hunter's instincts, and he knew of something in the area that he'd like to know for certain if it was still alive.

"It was, I dunno, weird," Sam said. "One of the other hunters was with us when you called, and she... reacted. Dean answered the phone and she kind of twitched and went pale." He glanced at Dean. "You didn't notice anything?"

"No," Dean said with a little frown. But then he might have been watching a waitress at the time...

Cas frowned. "Where did you see them last?" he asked. Because he had an idea he knew what was going on here, but he needed to be sure.

Because only the Winchesters could find one of the few wayward nephilim left in this world, or, worse, an antichrist.

"We just left them at the diner, but they're probably gone by now." And Sam and Dean had made it a point not to ask where the girls lived. It was easier all around if they didn't know where most of their fellow hunters actually lived. Bobby was the exception.

Cas nodded and vanished. He'd find a way to find them, or at least track them down to where they lived. Because he needed to know.

"I hate it when he does that," Dean groused, going to flop over on a bed.

"Wonder what got him so worked up," Sam commented. He shrugged and fell on the other bed, sprawling out.

Elsewhere, Runa was checking to make sure they had everything they needed for a vampire hunt. She had the hunting kit in their car open, and was sifting through to make sure the machetes were there alongside the vials of dead-mans'-blood.

Kyra stretched a bit as she helped make sure the car was packed. "So, when do we want to leave?" she asked, looking over at Runa. And then she stopped when she felt an angelic presence very close. She turned to see Cas at the end of the drive, surveying them both, his eyes just a tad wider than normal. This he had not expected.

Runa was about to open her mouth to reply when she felt the presence as well. She paused and very carefully turned around, and paled when she saw him watching them.

"Kyra...?" she murmured to her friend. Because it wasn't nerve-wracking at all to have an angel thirty feet away.

"Don't look at me," Kyra muttered. "I don't know what to do." Because she hadn't exactly had a lot of time with her father.

"You two have been helping the Winchesters." Cas could tell that, he could see the hunting gear in the back.

"Once or twice," Runa said cautiously, keeping her eyes on him. "Listen, we're just hunters. That's all."

"Hardly." Cas moved forward, looking between the two. "Although I have never heard of an antichrist and a nephilim working together."

Runa backed up until she was up against the car.

"We don't want any trouble," she said, her voice shaking some. She felt the slight pulse in her eyes that meant they'd turned black, and she scrambled to get control of herself again.

Cas tilted his head a little, surveying the two seriously for several moments.

"I believe you do not," he said quietly. "You have taken great pains to appear human."

Runa just nodded, blinking her eyes rapidly until they changed back again.

"We're just trying to keep our heads down," she said after a moment.

Cas nodded. He supposed that was a good plan of action for them.

"How much do the Winchesters know about you?"

"What does it matter?" Runa asked warily. "We're just hunters, that's all anyone needs to know."

Cas nodded. "Very well," he agreed, as if that was that. Because it was, to him. So he poofed back to the boys.

Runa blinked when he disappeared, and glanced over at Kyra. That seemed to be way, way too close.

Sam jumped slightly when Cas just appeared, even though he was mostly used to it by now.

"You're back already?" he asked. He kind of expected Cas to have just left.

"There is nothing of concern in this town," Cas said, looking between the two. It wasn't like he had anywhere else to go, and he wasn't going to go start distracting people this early. Besides, time with the boys could be restive.

"From the way you left, it sounded like there was," Sam pointed out. "False alarm?"

"Something of the sort." Cas sat in a chair, looking at the boys for a few moments. The nephilim and the antichrist hadn't wanted them to know, and if they didn't suspect anything, Cas wasn't going to say anything.
