Anna

She carefully lit the last candle circling Castiel's bed. The angel watched her tiredly, piercing blue eyes hazy with pain and exhaustion.

"This is a bad plan." He informed her. Anna raised an eyebrow.

"Do you have a better one?" She countered. The angel said nothing. She huffed out a breath, rolling her eyes.

'Didn't think so.'

"Mixing pantheons is dangerous." Castiel tried to warn her again. Anna smiled tightly at him.

"That's why we're not mixing pantheons. Just layering a few rituals. Then you charge it with your Grace. Once I set the circle, it should work like an echo chamber. No big flares of Grace, definitely not mixing any pantheons. Just one small, unnoticeable, uninteresting blessing." Anna carefully laid down the sand she'd collected from a portal into the Duat, in thick interlocking lines with the white chalk and the red string she'd already set down.

"Ok, it's ready." Castiel peered blearily over at her. Then slowly he reached out and tapped the first enochian sigil she'd drawn. White light flared and Anna began to hum quietly.

Cabin Twenty Six at Camp Half Blood housed the children of the nine muses; there weren't that many, and the self proclaimed cousins had all wanted to live together. A long time ago, before Anna had left for Stanford, their head counselor Syrinx Melos had taught her how to use music to boost power - regardless of godly parentage.

Music and prayer and mortal magic have gone hand in hand since the ancient times, across every culture, every divine belief. So Anna could combine them in anyway she likes and not cross into dangerous semi-forbidden territory.

Castiel reached for the next sigil and more blinding Grace-infused light flared, the power carefully contained inside the circle Anna had set. All anyone should see - if they cared enough to pay attention, which in the seventies none of her gods were, and neither was Castiel's garrison - would be some wonky pagan witch work. No demigod or angelic traces would appear, as long as they cleaned up afterwards.

Castiel slowly kept activating more of the symbols and sigils Anna had painstakingly drawn, and she kept singing. The sun outside the window dipped lower and lower in the horizon. Soon enough it was fully dark outside, even as Anna had to turn her head away from the blinding light show right in front of her. She closed her eyes, and let the weird energy of Castiel and his echo-boxed Grace wash over her.

It was almost as reassuring as Artemis's blessing. Although it wasn't the warm comfort of the goddess of the hunt blessing a hunter, the utter weirdness of the angel's Grace was a strong grounding reminder that this was reality, and not a Tartarus induced hallucination. A weird reality, but Anna would take it as long as she was solidly on Earth.

Finally the light in front of her began to die down. Anna very carefully cracked her eyes open again. Castiel was still slumped tiredly on the duvet of the motel bed, but the blood was gone and the hazy look in his eyes had vanished. She waited another few minutes for the rest of the power to be reabsorbed by the angel before she carefully blew out the candles and broke the chalk circle. The once blue black sand had turned white and hardened into smooth glass. The red string could be seen hovering, suspended in the murky white circle. She picked up the now sand turned glass and set it aside. She'll break it up and properly dispose of it later.

"Take off your shirt." Anna instructed, already tugging at his tie. She didn't wait for him to start unbuttoning, taking his chin firmly into her hand as she peered into the baby blue eyes. His pupils were even again, and were steadily tracking her movements. Anna slid her hands across the angel's sides, gently prodding, searching for signs of internal bleeding or broken ribs.

"My vessel is healed, but my Grace is still depleted from our trip here. I still require rest. I also cannot risk using too much of Heaven's power while we are in 1978 if we hope to go unnoticed." Anna sat back and scrutinized the angel.

"Ok. And I'm too crazy to go wandering around town half cocked unsupervised. What are we going to do about it?"

"I have enough Grace to send you to the Winchester's parents. It will, however, be a one way trip." Anna pursed her lips tightly. She could still feel the phantom pain from Castiel's botched healing last week. But the bulk of Artemis's blessing should have worn off by now, and even if it hadn't, she was technically in a time before she received the blessing.

In a time before she was even born.

Time travel is going to give her a migraine. She's having enough trouble holding onto her here and now, let alone sort out what it means to live life earlier in time. She's now living in a time where her parents haven't even met yet.

"Castiel-" She starts hesitantly. The angel turns only his head to face her, the motion so inhuman, that Anna tenses, instinctively reaching for a weapon she knows isn't there. The angel holds his hands out in front of himself placatingly.

"Peace. I understand your hesitance. But the last time I used Grace on you, it was to interfere with your healing. As a demigod, your healing is already impacted by your heritage. In addition to the blessing of the pagan goddess… it was a mistake to attempt such an endeavor. I will not make that mistake again. This will simply transport you to a new location. There should not be any adverse effects to you." Should being the operative word in that statement. Anna sighed.

"You know then." It wasn't a question. The angel eyed her curiously, bright blue eyes trained on her face.

"I can smell it."

"Right." She isn't surprised. Angels are old enough to know who and what demigods are. Most demons, and honestly most Veil monsters are too recent to know what a demigod is, let alone know how to track their scents. They're just happy to kill them because they kill things.

She's more concerned at this point about Castiel spilling her secrets than she is about him knowing them. Which Anna knows is probably a concerning insight into her dubiously repaired psyche. But she's going to ignore it; there are more pressing concerns than her many many many issues. She would put down several drachmas on managing to disturbed even Mr. D with her mental state.

"I will not tell the Winchesters." Her hand snaps up to stare at the angel. Castiel watches her through half closed eyes.

"Why?"

"You helped restore me to Grace. But you cannot keep it from them forever. You must tell them yourself, and soon." The angel warned her.

"It's better they don't know Castiel." She stands up, done with the conversation, reaching for her backpack. Before they'd left on their time travel adventure, she'd managed to steal a couple of knives from the back of the Impala when Dean when to grab Eleos. Neither of the boys trusted the sword much, but couldn't deny it's monster killing capabilities and had brought it with them to 1978. She tucked one down her boot and the other into the waistband of her jeans, the handle pressing against her hip.

"Why?" She glanced towards the clearly exhausted angel, suspicious. The first lesson anyone learned in Cabin 6 is that knowledge is always, always, power. There was a good reason why the Athena cabin is the most formidable cabin at camp. None of Athena's children require inherited powers of any kind to be the most dangerous demigod in a fight.

Even against Big Three kids - Anna has no doubt about her little sister's ability to fight and defeat Percy Jackson should the need ever arise. Anna knows that she could take both Nico and Thalia if she had too. Not at the same time, or in a fair fight; but she could. And for an Athena kid that is often all they need.

Information is dangerous, especially in the hands of someone as unknown to her as Castiel. But not giving him an answer was equally dangerous - he might renege on his promise not to tell. Anna pursed her lips, thinking.

"What do you think will happen if the boys learn of the monsters in my world? They're not clear sighted Castiel. Trying to hunt my kind of monsters will get them killed faster than hunting your kind of monsters already will. They've both died once already. If a greek monster kills them, Thanatos will not allow for another miraculous resurrection." Castiel opened his mouth, paused, then closed it with a sharp click. Anna shoots him a tense smile.

There was something the angel wasn't telling her. But Anna doesn't exactly have the time to tease the information out of him at the moment. Information is power - but Anna is acutely aware of the renegade angel heaven-bent on making sure that Sam and Dean are never born.

There would be time for an interrogation later.

She shouldered the partially emptied backpack. Most of her supplies had been removed; various spell and occult components lined up neatly against the far wall of the room, hidden from the door by the wide king sized bed in what was possibly the ugliest bedding she's ever seen. And she's seen Mr.D's idea of good interior decorating. Anna sighed heavily and turned back towards the bed. She really really hoped that she's not going to regret doing this.

"Ok Castiel. Do your thing." Anna closed her eyes as the angel's fingers pressed against her forehead.

She's got two idiot brothers to save.

AN:

I'm back!

This fic is def giving me a bit of trouble, so updates are probably going to slow down for a little while. But I do have the next couple chapters outlined already, so hopefully not too slow.

Like always, stay safe, drink water, wear masks, and spend a little time in the sun if you can!

Cheers,

Hartley
