Jody finished folding her clothes into her dufflebag, sighing and turning to look at the girls. Claire was spinning in the desk chair, and Alex was helping Jody pack. Sara was nowhere to be found – she'd be quiet at breakfast, and seemed thoroughly disappointed when Jody had told her that Sam was out hunting with Dean. She had retreated to her room, muttering about "college researching." Jody suspected she was feeling guilty over Castiel's situation – Sara seemed to think if she had agreed to help Lucifer, he may have beat Amara before she got too powerful. Despite the reassurance that this wasn't the case from her father, Jody, and the Winchesters, the teen still seemed distracted.

"I hate leaving like this," Jody huffed as she zipped her bag. "Especially since I don't trust you. No offense."

"None taken, we're pretty untrustworthy," Claire admitted. "But we're not going anywhere. My shoulder is killing me,and Sara's hands are still healing. Besides, with Delightful Demon Dad popping in and out, we wouldn't get far."

"Well, you've got a point," Jody agreed begrudgingly. "I really do want to stay though – I like taking care of you girls."

"You've got a town to run," Alex pointed out. "If you stay away for too long, Sioux Falls will fall apart."

Jody gave an amused little smile. "Alright," she sighed, picking up her bag. "Call me every few hours, and stay inside. I packed up some leftovers in the fridge, you just have to heat them up. The boys should be back by Tuesday. If you can't get a hold of me, call Donna. If it's an emergency call the boys or Crowley." She hesitated, biting her pinkie nail, trying to think of any other last minute details.

"Go," Alex urged gently. "We'll be fine. Promise."

Jody didn't look convinced, and Claire sighed.

"Look, we already have plans for the day," she said, standing. "Gavin and Roland went to Singers to pick up the Chevelle. Dean's idea to keep me out of trouble."

"I'm going to install some security cameras around the bunker and set up a system that will directly link them to some monitors in the basement. I'll probably hack into local traffic cameras and connect them, too," Alex added.

"And Sara . . ."

Alex and Claire looked at each other, hesitating. Honestly, they had no idea what was up with Sara. She'd been holed up in her room, of course, and wasn't one for conversation at the moment.

"Sara . . ." Claire started again, searching her brain for a white lie she could tell Jody to appease her.

"Sara's cleaning." Everyone look started as they looked towards the door, where Sara, carrying a large box, had paused. Her hair was thrown up in a messy bun, and was struggling under the weight of the box.

"Whatcha got there?" Claire asked hesitantly.

"Who knows?" Sara replied, voice chipper. "There's an entire room downstairs across from the dungeon full of these old boxes. There could be all sorts of fascinating things left over from the Men of Letters."

She continued down the hall, and after exchanging glances, Alex, Claire, and Jody followed.

Sara sat the box down on the floor, shoving some pieces of stray hair behind her ear before unfolding the top and delving into the contents.

"You okay?" Jody asked, frowning.

"What? Yeah. Fine," Sara replied, pulling some wooden boxes out of the box and stacking them neatly. "Just, you know. Keeping busy."

"You're stir crazy," Jody remarked.

"No," Sara argued. "No, just sick of sitting around doing nothing."

Jody knew there was nothing she could do to unwind her. She tried to stifle a sigh and leaned down, kissing the top of Sara's head. "Easy on your hands," she reminded her, and Sara nodded.

Not long after Jody left, Claire's curiosity was piqued, and she was helping Sara unload boxes. Soon the entire downstairs room had been cleared out, boxes surrounding them upstairs. After Sara received a text from Jody a few hours later, informing her that she was home safely, Sara stood.

"What's up?" Claire asked.

"I had to make sure Jody was gone. Alex, are those cameras working?" Sara called, heading towards the basement. Frowning, Claire scrambled to stand and follow after her.

"Yep, you're good to go," Alex replied, turning to glance at them as they entered the room. Several monitors had been hung on the wall, showing multiple rooms inside the Bunker, the outside areas, and the garage. In the corner, traffic cams flickered.

"Sick setup," Claire admitted. "But I feel like there's something I don't know here. Why are you guys being all secretive?"

"Well we would have told you about this earlier, but you were spending so much time with my brother," Sara said innocently.

"Hey, I –"

"I'm joking with you. I had an idea earlier and Alex had the same idea."

"It's about honing our skills," Alex agreed. "We have the shooting range and weapons and stuff to practice with, but there's still so much about Sara's powers that we don't know about. So she needs her own space to practice."

"And that's why we spent the day cleaning out a creepy old storage room?" Claire raised her eyebrows. "Why not just use the living room? There's more space, and less asbestos."

Sara and Alex hesitated. "Some of the tests I want to put myself through aren't really things I want Sam and Dean – or Jody, for that matter – knowing about."

"I'm not a big fan of this idea, either," Claire frowned, crossing her arms.

"Please, I'm not sacrificing babies or anything," Sara rolled her eyes. "Look, if I'm going to figure out what I can do, I need privacy, where the boys won't gawk."

"We'll start simple," Alex suggested.

"We?" Sara raised her eyebrows.

"You're not doing this alone," Alex replied. "Let us help."

Sara glanced from Alex to Claire, and begrudgingly nodded.

"So let's talk about what we know," Alex suggested as they made their way to the gutted room. It was bare bones, gray concrete floor and brick walls, and a few lightbulbs hanging from the ceiling. The only things inside it was a table and a few boxes. "Sara doesn't get stuck in Devil's Traps like a regular demon."

"How do you know?" Sara asked with a frown.

"Right, I forgot. When we first found you, you passed out before we got home," Alex replied. "There's a Devil's Trap painted under Jody's rug – you would have been trapped when you went over it."

"So it can't trap me," Sara confirmed. "But we don't know what sort of affects it might have on me."

"Good point. There's some chalk in that box over there," Alex nodded.

"I got it," Claire said, digging through the box and coming up with a few thick pieces of chalk. She went to work on the concrete floor.

"While she works on that, we can go as basic as it gets," Alex continued, and Sara raised an eyebrow in question. Alex held up an old book. "Exorcism."

Sara shrugged, leaning against the table and crossing her arms. "Alright. Hit me."

Alex hesitated for a moment, before flipping to a marked page and clearing her throat. "Exorcizamus te, omnis immundus spiritus, omnis satanica potestas omnis incursio infernalis adversarii . . ." she glanced up at Sara, who hadn't budged. "Anything?"

Sara shook her head. "Nothing."

"I wasn't expecting much," Alex admitted. "You were born half demon, there's nothing possessing you to exorcise."

"Trap's finished," Claire said, standing up. "Maybe I should go to art school."

"Come on, that's the worst circle I've ever seen," Alex retorted.

"It's mostly okay," Claire said defensively, mumbling under her breath, "Stupid Sam and Dean making perfect stupid circles every stupid time."

Sara pushed herself off the table and frowned at the circle – it was almost like she could feel it, but not quite. Like the air was vibrating around it. She stepped into it, frowning at the odd sensation.

"Anything?" Claire asked.

"It's tense," Sara admitted, waving her arm through the air. "It's like the air is thick."

"Try moving something," Claire said. She held up the piece of chalk. "Here. Knock this outta my hand."

Sara concentrated all her willpower into moving the chalk, for several long minutes in fact. She strained herself against the pressure around her, but finally let go and stepped back, shaking her head. "I can't. But that doesn't mean anything. I can only move things sometimes."

"But you're not trapped," Alex pointed out as Sara stepped out of the trap, instantly relaxing as the pressure was relieved. "So that's a good thing."

Sara nodded, catching her breath for a moment. "What's next?" she asked, leaning against the cool wall.

"Let's go down the list," Alex said, opening her book again. "Alright . . . iron?"

"I've never had a problem with it," Sara replied. "I've touched it plenty of times."

"Okay . . . salt?"

"Are you kidding?" Claire snorted. "You've seen the amount of salt she puts on her fries!"

"Yeah, you're right," Alex nodded, and Sara looked sheepish.

"How about . . . oh."

"What is it?" Sara asked.

Alex looked concerned. "Erm . . . holy water?"

Sara shook her head. "I've never been in contact with it."

"Sam and Dean keep some upstairs," Claire said hesitantly. "But, I think it's a bad idea. One time I threw some at your dad –"

"What?"

"– and he was really not happy." Claire shook her head. "I think it's a bad idea."

"We won't know until we try," Sara insisted, turning and heading upstairs swiftly.

Claire looked at Alex. "You worried about her?"

"Oh yeah," Alex nodded. "You?"

"Duh. Man, she's really beating herself up over this whole Lucifer thing, huh?"

"It's not surprising," Alex admitted. "Sam and Dean are really good at the whole guilty conscious thing. She really looks up to Sam, you know."

"She said that?" Claire frowned.

"Of course not. But think about it, they're a lot alike. They both lost their moms when they were young, they grew up as black sheep. They've both been victimized by Lucifer. They both have daddy issues. Bossy older brothers. He gets her, and she gets him."

"You don't think our little Sara is harboring a crush on Sam, do you?" Claire grinned.

Alex laughed. "Are you kidding? I mean, Sam and Dean are great looking – like really great looking – but come on. They're Sam and Dean."

The girls stared at each other before bursting into laughter, and they were still roaring as Sara reentered the room, holding a jar of clear liquid.

"What's so funny?" she frowned.

"Nothing," Alex said quickly, sobering up. "Claire was just pretending to care about school."

"That is amusing." Sara moved to the table, setting the jar down and unscrewing the lid.

"Right," she said, turning and looking at her foster sisters. She held out her arm, rolling up her sleeve. "Go on, then."

"Whoa, slow down," Alex said, stepping forward. "We're not gonna just pour holy water on you."

"Well we have to see if it works," Sara replied. "Go on."

Claire and Alex glanced at each other nervously.

"One drop," Claire said, moving forward. "And that's it."

Sara nodded, and Claire rolled her own sleeve up, dipping her hand into the water for a moment before moving towards Sara, hand dripping. She glanced at Sara, whose heart was racing. "Ready?"

Sara swallowed and nodded.

Claire hovered her hand above Sara's letting a droplet of water fall from her fingertips before pulling her hand away.

The moment the water made contact with her skin, there was a sharp sizzling sound and steam rising off Sara's arm. She hissed and grabbed the spot, ignoring the dull throbbing in her hands.

"Sara?!" Alex demanded.

"It's fine," Sara ground out, stepping back. She shakily moved her hand, glancing at the skin where the water had come in contact. It was similar to a cigarette burn, round and puckered, as though acid had been dropped on her skin.

"We shouldn't have done that," Alex hissed.

"No," Sara said, taking a breath. "No, it's fine, it's good. Now we know."

They were quiet for several moments, before Alex said quietly, "I think that's enough for today."

The others agreed, and started to gather their things.

"You guys go ahead," Sara told them. "I'm going to do some organizing down here."

Claire and Alex bot knew that was a nice way of saying she wanted to be alone, so they agreed, and headed upstairs to scrounge up some dinner. Sara, meanwhile, stacked a couple of boxes. She balanced some beer bottles on the boxes and stepped back, taking a deep breath. She remembered the power she'd felt while in the presence of the Hand of God – the way she was able to move things with a thought, how she'd crushed that lock like it was nothing. She could feel her abilities inside of her, but she couldn't get it to listen to her.

So maybe she should try listening to it.

She closed her eyes, letting her mind wander to where it wanted to go. For whatever reason, it went to the very back of her mind, to a memory. She and her mother were walking in the park, and Sara ran ahead towards the duck pond. Her mother smiled as she followed, picnic basket in hand. Sara giggled in excitement, small legs carrying her quickly, until she bumped into something – someone. She glanced up, finding that she'd run into a tall, frightening looking man, in a long coat and a hat. Intimidated, Sara scrambled backwards. The man glanced at her, and even at four years old, Sara could tell something about him was wrong. His eyes frightened her, seeming to glow for a moment, before he smirked and looked away, strolling away casually. Regina's eyes followed him, her beautiful face pulled down in a suspicious frown . . .

Sara was startled back into the presence as the bottles burst, exploding shards of glass. All three had seemingly shattered at the same time, and Sara felt exhausted by the wave of power she had unwittingly emitted. Though she'd only meant to knock the bottles over, she wasn't entirely displeased with her results, but she was definitely more than a little concerned.

She rubbed the burn on her arm self-consciously, frowning at the broken glass, and wondering why she'd just remembered something that had been buried for years.
