Milly breathed in the fresh Montana mountain air as she walked beside Sam to a secluded area away from passing cars or anyone who might witness the entirely supernatural activity that was about to transpire. It had been a week since the Jesse situation where they discovered they had no idea what the kid was capable of so they wanted to find out before she "accidentally sneezed one day and killed them all", to quote the insightful Dean Winchester.
Sam, having subsidiary experience in the area of telekinesis, decided he might be able to help her figure out what she could do. She had begun by moving around small car parts around Bobby's junkyard, gradually increasing the size of the objects as Milly grew more comfortable. However, while they were on the road, they needed to be more creative as well as more discreet.
Milly played with her anti-possession bracelet that Bobby had made her as they entered a small clearing in the woods.
"Okay, try taking these sticks and forming a square with them on the grass," Sam suggested, placing four sticks on the ground in front of her. With full concentration, she held her hands out and lifted the sticks one by one laying them down in the shape of a slightly crooked square.
"Nice job Mils. What about that rock?" He asked, gesturing to a rock that he estimated to be no heavier than thirty pounds. She held her hands out again and slowly began lifting the rock off the ground, causing Sam's mental gears to turn.
"Can you throw it?"
"Throw it?" She replied in surprise.
"It doesn't have to be far, you got this."
Milly took a deep breath and threw her arms forward, feeling a slight tug from the weight of the rock. It hurled between a couple of trees and landed in a pile of dead leaves and dirt. She turned to him with a cheerful smile
Suddenly an idea popped into Sam's head and he looked at her in curiosity.
"What about that?" He pointed behind her, and she turned around to see an enormous fallen tree before whirling around to stare at him in bewilderment.
"Sam, that's huge!"
"I know, just try to move it Mils." He replied encouragingly. The girl sighed and turned to the tree trunk, taking a few steps back. The tree easily exceeded the length of 100 feet with a wide diameter. She felt a little lightheaded, but she needed to try this. Sam watched and held his breath in anticipation as she held out her hands in front of her.
Nothing.
She dropped her arms sadly and he walked over to her, putting a hand on her shoulder.
"That's alright Milly, it's a tough one, we'll get there."
She looked at him briefly before turning back to the tree and holding her hands out firmly. Sam took a step back in surprise as Milly closed her eyes and took a deep breath, ignoring every thought in her head.
Sam was so distracted by watching Milly he almost didn't notice the tree slowly lifting into the air just barely an inch above the ground.
"Holy shit," he whispered.
She opened her eyes and squealed in excitement just before it dropped to the ground with a loud thud.
"It was floating!"
"You did it." Sam laughed and watched as Milly's eyes lit up with happiness.
They began to head back to the motel which was just a short walk away. However, they hadn't even reached the parking lot when Milly's limbs started to grow heavy. It felt like she was being pulled towards the ground as she walked and a faint ringing in her ears made her grimace.
"Milly, you okay?" Sam wondered, noticing she was starting to fall behind.
"Yeah, I just-" Milly stopped in place when her surroundings began to spin slowly. When he realized she was about to collapse he grabbed her and picked her up, just as she passed out.
"Milly? Shit." He muttered to himself, rushing the rest of the way to the room.
He barged through the door causing Dean to jump in surprise.
"What the hell happened?" He asked, noticing the girl unconscious in his brother's arms.
"I have no idea. We were walking back and she just passed out, out of nowhere." Sam explained, gently laying her down on the couch as Dean made his way over.
She looked peaceful like she was only sleeping as her chest rose ever so slightly, indicating she was breathing without trouble.
"What do we do? Do you think we should take her to a doctor?" Sam asked, crossing his arms anxiously.
"How should I know? What the hell would we tell them?"
All of a sudden they heard the sound of angel wings behind them and turned to see Castiel, a murderous glare in his eyes. An angel blade dropped from his sleeve into his hand and he advanced toward Milly.
"Cas-"
"Move away from the child." He demanded, but Dean stepped in front of him and put a hand on his chest, pushing him back.
"Dude, what is the matter with you?"
"That is not what you think," he growled, pointing to the unconscious girl on the couch.
"What are you talking about Cas?" Sam asked in bewilderment.
"I couldn't sense it before. It was too powerful. But just minutes ago I felt it. And if I felt it that means many others did too. Angels and Demons. She's going to lead them right to you."
"What?" Dean repeated in confusion.
"The girl. She isn't human."
"You couldn't sense that before?" Sam asked curiously.
Cas paused and narrowed his eyes at the brothers.
"You knew she wasn't human?"
"Well yeah. Human kids don't grow nine years in a week and move things with their minds." Dean retorted and Cas stared at Milly in fascination.
"Cas, she's half human, half god."
"...and Dean is the human parentage?"
The brothers nodded and Cas began looking around the room apprehensively.
"Who is the mother?"
"Athena."
A look of grave understanding crossed the angel's face as though he knew her personally.
"She must be warded immediately." He stated, moving past Dean and over to her. Sam stepped in front of her, blocking Cas' path.
"Sam…" he warned, losing his patience.
"She's a little kid Cas."
"I'll be quick."
The brothers shared worried glances before Sam hesitantly let Castiel through. He placed a hand on her chest and a yellow glow appeared just before she startled awake with a pained cry. Milly began to try and scramble away, not knowing what was going on, but Cas pressed his fingers to her forehead and she passed out again.
"I need to get the three of you out of here now. Whoever else sensed her will be here any minute."
Bobby sat at his desk, reading a print too small for his eyes when suddenly two hunters, a kid, and an angel appeared in his living room causing him to nearly jump out of his skin.
"What in the hell!"
"Sorry Bobby, we've got a situation," Sam explained as his brother laid an unconscious Milly down on the couch.
"When do you not? What did you idjit's do to her this time?"
"We have no idea. Cas, can you explain?" Dean asked the angel who furrowed his eyebrows at him.
"What're you looking at me like that for? You already carved me up."
"Since when are you intimate with deities?"
Sam and Bobby watched in amusement, and Dean stared at the angel uncomfortably.
"Uh, I'm not. I didn't know she was-i don't have to explain myself to you, just tell us what's going on!"
The angel tilted his head and looked at him in confusion before turning and walking a few steps away.
"There aren't many beings in existence which radiate power like that, I thought she might've been a Nephilim."
"Those really exist? Half human half angels?" Sam wondered.
"They are abominations, entirely too dangerous to be kept alive.".
"And that's what you thought Milly was?" Bobby asked.
"Yes, it appears her powers are inoperative while unconscious. Without the concealment of her powers, she's like a beacon of power. Anyone searching for you would've been able to use her to find you." he explained, facing the other three again.
"That would've been good to know beforehand," Dean grumbled, running a hand over his face.
"What's interesting is the amulet she's wearing." Cas continued, causing all three men to look at him in curiosity.
"What about it?" Sam asked.
"There's powerful witchcraft attached to it. Some of the most powerful I've ever come across. Whoever enchanted it had a lot of power to channel."
"The kid has a magical necklace." Dead nodded to himself. He wished he could say he was surprised, but he wasn't.
"Do you know what it's for?" Bobby asked, ignoring Dean.
"May I?" Cas asked, gesturing for the amulet and they nodded. The moment he unclasped it, he took a step back in surprise.
"What it is?" Sam demanded.
"Usually angels can see other angels, deities can see other deities. Angels and deities can see each other-"
"Yeah, we get it."
Cas paused and looked at Dean in annoyance before continuing.
"This amulet prevents everything from seeing what she is, including her own kind."
"Why would Athena hide her from other gods?" Sam wondered out loud, and before Cas could respond, Milly began to stir. As she slipped back into consciousness, her eyes slowly opened. The room spun in circles, making her want to close her eyes again until she heard a voice.
"Milly?"
She looked up at him disoriented. His face was only moving a little bit, but she could tell it was Sam sitting on the couch beside her in Bobby's house.
"How'd we get here? What happened?" she whimpered, making Dean's stomach churn. He hated how scared she sounded.
"I carved angel warding symbols into your ribcage and then brought you here so you cannot be found by angels," Cas responded simply, causing the three men to look at him incredulously.
"Gee Cas, way to sugar coat it," Dean muttered before snatching the necklace from his hand and bending down in front of the girl.
"Are you okay?" He asked, clasping back around her neck, and she looked at him fearfully.
"Mhm. I think so," she replied, looking down at her chest where it appeared like nothing even happened.
"What do you remember?" Bobby asked.
She wasn't sure what she remembered. Milly was used to not having any idea what was going on. She only had about a month's worth of memories to begin with, but she had never experienced something like this before. She was there, why couldn't she remember?
"You seemed fine while we were outside. Weren't you?" Sam asked, and Milly looked up at him.
Outside. They were outside.
Suddenly it all came back to her, the rocks, the tree, walking back to the motel.
"Well, I was feeling a little dizzy but it wasn't anything serious."
"Well kinda seems like it was." Dean retorted and Milly frowned at him.
"How was I supposed to know? It's never happened before."
"Maybe you pushed yourself too hard this time?" Bobby suggested.
"Maybe…I feel fine now."
"Okay, so what, you've got a demi-god battery?" Dean asked.
Milly snickered in amusement and he furrowed his eyebrows at her.
"Demi-god battery. That's funny." she smiled.
"Yeah, it's hilarious," he grumbled before turning away.
"Where is Athena now?" Cas wondered, looking at the brothers and Sam shrugged.
"We have no idea. She kinda just fled."
"Yes, I heard something about that. She received a prophecy from an oracle."
"Yeah, it doesn't make any sense," Milly added, looking down at her legs as she swung them off the side of the couch.
"You have it? May I see it?"
Bobby dug around through his desk and handed Cas the paper on which Sam had written out the translation. Milly tried to get up to walk over to the angel, but Dean kept a hand on her shoulder preventing her from standing.
"Athena said in her letter Zeus is hunting her, do you know why?" She asked.
"I believe you are the reason why."
Milly's heart dropped and she looked at him in surprise as he read the prophecy from the paper.
"Why? What did I do?"
"Nothing, I'm sure. It's simply your birth that he'd been trying to prevent. Your mere existence threatens his."
"Why would "the king of the gods" be threatened by a kid?" Dean wondered.
"More by who she's to become."
"And who's that?"
"Your translation was slightly off. It's not rain as in precipitation, it's reign as in sovereignty. If the rumors are true, it is prophesied that this child will kill Zeus and end the reign of the Olympians."
