This is just something I was messing around with because I was stuck on my other fics. Warning, you have to read Destiny Calls, and know characters from the Arrowverse (DCCW).

Caitlin Snow's POV (Earth 1)

One could say that it wasn't the greatest day today.

Sure, Barry was back, my powers were more or less under control, Cecile and Joe were happy together, even Harry was back, but still, it seemed like everything was just going the other way for us. And I don't mean bad luck, we had enough of that with Becky. I meant, just everything was a complete mess.

First off, a woman just simply appeared out of nowhere in the middle of the cortex.

She looked normal enough, but all meta-humans do. Well, most of them, but that's beside the point. Calling her a woman wouldn't be the technical term, she was more likely an adolescent teenager, probably about 16. We would have asked, but she was unconscious when she appeared, so just in case, we put her in the pipeline.

When she woke up, she was rambling in a different language, and it was only then I started paying attention to her.

She had black curls, and I don't mean brown-black like Iris, but actually pitch black. They cascaded down her back, like curtains draping a window. She wore a green leather jacket, a sleeveless dress in a deeper shade of green, and black thigh-high boots. She was quite tall for a teenager, probably standing at about 5'4 or more, and had large, silver eyes.

This was when I was sure that she was a meta-human.

My lovely alter-ego/roommate, Killer Frost, had icy blue eyes. This stranger's eyes were similar, not grey, but not white either. They didn't just look silver, they glowed silver, and had a slight yellowish tint to it, like a wolf. Probably not the most technical term I've used in ages, but that was beside the point.

"Could you tell us your name?" I asked tenderly, and she glanced at me. "My name's Doctor Caitlin Snow, this is Cisco Ramon,  Barry Allen, and Joe West. You're in STAR Labs. Do you know how you got here?"

Her lips mouthed my words. "STAR Labs? You're Caitlin Snow? Killer Frost Caitlin Snow?" She asked, confused. Her voice wasn't what I had expected. It wasn't your average stereotypical teenage girl voice that I was so used to as a high school student. I didn't have much experience on this sort of things, but her voice carried pain with it.

"How did you-" Cisco started. "Mind reader? No one knows Caitlin's... friend."

"And if she really is Killer Frost, then you're Vibe. And he's the Flash." She mumbled to herself in another language for a while, until Harry ran back in.

"Yo, Harry, have you found out what language she's speaking?" Cisco asked.

"I haven't found a match yet, but it seems like an ancient dialect of Greek, or Latin. It's not on any of our databases or yours. If she can talk in a dead language fluently, who knows what else she can do."

"She has ears." The girl interrupted. "And you must be Doctor Harrison Wells. And I'm presuming Earth-2 since you're not in a wheelchair."

"Okay, lady, can you tell us who you are now? Cause you are really freaking me out right now." Cisco stated, hands gesturing as she spoke.

"Are you from another Earth? You seem to know about the multiverse." Barry asked, arms crossed.

"This is not happening." She sighed, before looking around. "You locked me in the pipeline? That is just plain rude. And, I'm sorry to say, Cisco, but I can find so many faults in this cell." Her form shimmered, and she turned to silver smoke, and then reappeared right in front of us.

"Woah." We all stumbled backward, and I held onto my clipboard tightly. Not now, not now, please don't come out now. I thought to Killer Frost, who was trying her best to gain control.

"Is the Ice Queen bothering you, Caitlin?" She said head cocked. "I'm sorry. You're just thinking really, really loudly, and I can't help but hear you."

"Meta." Cisco pointed. "Harry, can you do the honors?"

"We just saw her dissipate into smoke and then appear through your apparently not-impenetrable glass doors, Ramon, I'm pretty sure she's a meta-human," Harry said with a scathing tone, before pointing his watch towards her, but it didn't beep. "What the-"

"I'm not a meta. And I'm pretty sure that this is not my multiverse. Just checking, 53 Earths?"

"52." Barry corrected.

"No, 53," Harry answered. "Go on."

"Earth-38 is Kara's home, the world of Supergirl, Superman, and Batman?"

"I don't know about Batman, but the other two, yes."

"And HR is from Earth-19 and he was killed by Savitar."

"How did you know that?" I asked. "No one knew HR was HR. He went around as-"

"Randolph Morgan." She nodded. "Okay, this is worse than I expected. Okay, I'm not an alien, I'm not a meta, and I am not from any of your 53 Earths."

---

"I don't understand. I thought there were only 53 Earths, and that's weird enough. Then where are you from?" Joe asked.

"Born in Brooklyn, grew up in New York."

"I didn't mean the place." Joe sighed. "I meant what weird science place are you from."

"Weird science place would be you guys where I come from you guys are just TV shows and comic book characters." She snapped. "How many bus-metas have you found? Kilgore?"

"Found. Becky as well. That's it." Cisco said. "How do you know?"

"As I said, you guys are just a TV show to me, and I need to know where you guys are up to so I don't mess up the time stream. Just, treat me like I'm from the future. And I need a way home."

"Who are you, exactly?" Iris asked hands on hips. "Because you really haven't answered that question."

She sighed again and looked at us. "Since I've confirmed you guys aren't from my world I guess my identity is safe with you." She sighed once more, before looking at us with serious eyes. "But what I am going to tell you is completely confidential, and you are not to tell anyone about it, or me. And it's going to sound way off the charts, weirder than anything you guys have faced, but you're going to believe me because I'm from a different multiverse where things are that weird."

"Sure. Go ahead." Barry nodded, and she took a deep breath.

"My name is Arthella Dianne Carter, daughter of Poseidon, and gifted with the abilities of Artemis and Athena as my patrons or adopted parents, born to Tasha and William Carter in Brooklyn, December 21st 2002. Even though my physical age is 15 I am actually approximately 22, and that is because I am the goddess of Time. An actual god, not like Barry's time remnant's mythology. My father is also a god, one of the Olympian Council, and so is almost everyone else in my life, except most of my friends, are demigods, something I used to be. You can call me Thea, there's no need for bowing or groveling, and I really need to have some lunch so please tell me you guys have Mcdonalds here."

I shook my head. "That's the first time I've heard of that. Every time someone comes they ask for Big Belly Burger. I guess unfortunately that proves you really aren't from around here at all since there's Big Belly Burger on Earth-2 and 38."

"And how exactly did you just do-" Cisco gestured with his hands. "That?"

"That's photo-kinesis, isn't it?" I added. "You can manipulate compressed hard light beams like Ray's ATOM suit and Doctor Light, but moonlight instead of starlight or dwarf star alloy. That's amazing. And I'm also guessing you have telepathy as well?"

"Telepathy, photokinesis, hydrokinesis, cryokinesis, aerokinesis, chronokinesis, telekinesis, teleportation, flight, super speed, invulnerability, biomorphism, the list goes on." She listed off as we stared in awe. "Cisco's ability to vibe I don't have, unfortunately, and since I'm not of your multiverse Cisco hasn't been able to vibe anything from me. Correct?"

"Yes, you are." Cisco sighed. "How are you right about so many things?"

"How do you have so many powers, and you're still just a teenage girl in high school?" Iris asked. "Like if I had your powers, I would be zipping around in a costume like Barry fighting crime."

"High school I chose to continue attending so I don't lose my mind," Thea added. "And, yes I do zip around in a costume to fight crime, just at night, because I can't exactly go out during the day. The NYPD does a good job where I'm from. Plus, I'm more like Oliver than Barry and Kara. You and Kara are superheroes, going around in broad daylight. Have you seen Oliver going around in the day? We're more like vigilantes, not heroes. I'm no hero."

"I don't know what the hell you guys are talking about, because I just got my head around the multiverse and different Earths, but now it's just crazy. Have you killed anybody before?" Joe cut in.

"Yes." She said without flinching. "I've killed monsters who wear human faces, and I mean that literally. I have plunged a dagger into a living soul's chest without even thinking about the consequences because they deserved it. I have watch friends and family alike fall. I have been through hell and back, not one, not twice, but three times, but that's only counting the times I've fallen into actual hell. Some may not believe me when I say that I've been through more than Oliver Queen, who spent 5 years abroad. Does he tell everyone that he was on the island for 5 years? Because the first, second and fourth one, yes, but he was in Hong Kong for the third year, and he joined the Bratva in the fifth year."

"How are you alive?" Iris asked. "I assume because of your abilities. But how?"

"I have friends. I had family. Friends who are going to tear the city apart looking for me because even though I disappear alot if the gods can't find me they can't find me." She answered.

"Can I see you suit? Do you have toys?" Cisco asked.

I clucked at him. "Cisco! Is that honestly what you're thinking about right now? Her suit and her vigilante life? We have to try and get her home!"

"It's okay, Caitlin." She smiled, and her form flickered. Instead of the casual attire, she was suddenly in a fully geared suit. It was a simple black tank top with a similar green leather jacket, but this one slightly longer and more swishy, and instead of a skirt, she had form-fitting combat pants and boots, all with sheaves for knives and an assortment of weapons. From what I could see, she had more weapons on her than Oliver, and that was saying a lot.

A green mask covered her nose and mouth, and her hair was no longer pure black: there was a strand of snowy white hair on either side of her head, contrasting greatly against her dark hair. She noticed me watching her, and smiled. "It's nothing, Caitlin." She said reassuringly, twirling the white strands of hair. "Like, sure, it isn't fashion statement of the year, and I didn't purposely dye it like this, but it's just a little reminder to myself to not strain myself too much."

"Why?"

"Because I can't hold up the world on my own for too long. That's how these came to be. My brother and his girlfriend used to have the same strands, but they faded a long time ago. But for me, as a permanent, immortal, never-aging goddess, it wasn't going away soon."

"Can I see those knives?" Cisco asked eagerly, ignoring our conversation. "I can touch them, right? Because Oliver was really touchy about me messing with his stuff."

"If you can pick it up, be my guest." Thea smiled, pulling out one of the daggers on her belt and placing it on the table.

"What, is it like, super heavy?" Cisco asked, walking over, and as he reached to pick it up, his hand passed right through to the table. "What the- What technology is this? Does it shift its density to nearly intangible if it isn't your fingerprints?"

"It can't sense fingerprints on me, I wear gloves." Thea pointed out. "And no. Stygion iron cannot be touched by mortal hands, neither can Celestial bronze and Imperial gold. You guys fight criminals. I fight monsters right out of the history books themselves. It's like Nth metal, the type of metal Kendra's weapons are made out of. Special weapons for special monsters."

"For once, I have no modifications for your suit, except do you have anyone that runs the technical part for you?"

"I can hear your heartbeat from here, Francisco." She answered with a smirk. "My partners could just whisper the information to me from a mile away and I could hear it. Also, did you forget I'm telepathic?"

"Right. Psychic links are way more secure than comm links. Can't hack a psychic frequency, can you?"

"Actually you can." She laughed. "Individual psychic have their own trademark signatures or patterns that can be tracked or hijacked."

"Um, guys?" I asked, diverting my attention to the screens. "Armed robbery in progress in New Brighton. Police are not going to make it in time."

Cisco looked at Thea, a wide grin on his face. "Care to show us what you've got- what's your codename? I've got one, what about Luna?"

"That's unoriginal." She laughed. "I go by Nightingale."

"Ooh, catchy." Iris added on the side. "But seriously, get moving."

"Fast is how I roll." Thea winked, and disappeared. See you there, Flash.

Thea Carter's POV

When we arrived, by mind was racing.

I was literally, stuck in a TV show.

There were so many things I could do that would affect the storyline. I could help save Martin Stein. I could warn them about DeVoe. I could stop Barry from getting arrested. I could do so many things.

But sometimes, I wasn't allowed to interfere.

We're on site. I told them, and I grinned under the mask. Finally, something that was universal. A fight.

I looked at the armed guards and snorted. Pathetic. With a swift jump, I unsheathed my blades and chopped their guns in half. Barry looked at me, and muttered "Damn," under his breath.

"Never seen a badass woman before?" I asked. "Pretty sure you've worked with women vigilantes before."

"Yea, I have, but none as fast as you, Nightingale."

I'm a goddess, Flash. I replied. You're just a man who got struck by lightning.

He shook his head, but suddenly, a wave of bullets came firing at us. Barry ran from them, but they seemed to follow him around. Barry continued to run, but the bullets, no, spikes, kept following him. "Oh, heck, I remember these. Microtechnology attracted to kinetic energy."

Okay. Watch out, this might hurt. I readied myself, and as he turned a corner, I launched myself at him, spreading out my wings as I did. The spikes embedded themselves in my feathers, and I shook them off. You are very welcome.

"You have wings?" Barry exclaimed, shocked. "That is not fair!"

"Life's not fair, Flash," I answered. "I did say I could fly."

"You said aerokinesis. I thought flight was included in that!" He argued.

I looked at him and smiled. "Maybe I'll stick around for a bit longer. Artemis knows that every huntress needs some time alone. She'll keep my friends from going insane for a bit. But... I still need a way how first."
