2 + 2 = Chaos

I know that this one isn't very interesting, but you will probably have to read it for a bunch of future story's and it's really not that long so just stick with me for a little here.

1. Percy meets Sara

Honestly, sink shower and stuff needed to hire more reliable employees. Sara had been reported dead twice, is constantly throwing knives at things, and is frankly terrible with helping people at the store. Percy had basically no record of anything she has done in life except minimal school records and other things of the likes (It was a miracle no one had figured out they were fake yet), is terrible at taking orders, and had a higher sass level of anyone you have ever met. And they were both idiotic dumb-asses.

They both knew that there was something off about the other, but Sara didn't want to approach Percy because she was still only a teenager and didn't want to seem stalkery, and Percy honestly didn't care that much.

Until one day, when Percy walked into the storage closet, and Sara threw a knife at her head. It was an accident as Percy, who had ducked, had sneaked up on her, and no one could do that, so really it was just a reflex. When Percy hesitantly stood up, she gave Sara, who looked shocked, a wary look.

"Jesus fucking Christ lady, a little warning next time maybe?" Sara came back to reality, even if a little more shocked by Percy's joking personality.

"Sorry 'bout that. A reflex, ya know?" Sara thought that this was the perfect chance to get to know Percy a little better. Percy exhaled.

"Ya know, lady, if you've got a question, you should probably ask it before I leave here and decide to never talk to you again because you through a knife at my head." Sara was shocked for a third time by what Percy had said, but quickly got over it.

"Whats up with you? Your different, I can tell, but I don't know what about you is different. Somethings up." Percy smiled at her.

"You're pretty freaky to, lady. What do ya say, we get to know each other, try to figure each other out, and either we do manage to figure out whats up with each other, or we trust one another enough to just tell each other. We got a deal?" Percy put her hand out for Sara to shake. Sara nodded and extended her hand. They shook on it.

"But first, I might be needing your name. I can't exactly keep calling you that weird-ass kid now can I?"

"it's Percy, Percy Jackson."

"Nice to meet you, Percy, I'm Sara. Sara Lance."

Six Month later...

Sara and Percy finally know what's up with each other, and get along great. They call each other their sister. It was a joke at first, but now they really think of each other as sisters. Sure, ones a time traveling assassin and the other is the most powerful demigod in history, but their sisters. Sadly, Sara has to go save time again and Percy defeated the traitorous God that had traveled to earth-1 (Percy can mist travel to different earths because I said so) to do some evil villainous shit and had to leave to go on a different quest, so they parted ways, each with the others phone number and a promise to visit at least once a month.

2. Sara and Percy meet Natasha

The two sisters had finally gotten a break and decided to go on a little vacation together. Sara had gotten one of those earth-traveler thingies and the two met up on earth-53 (If in the DC universe there is actually something cool on this earth, pretend it's a different earth because I just decided on earth-53 because they call earth planet C-53 in the MCU so...), not really for any specific reason. They had just been wandering around, when they spotted something a little out of the ordinary. I woman, clad in black leather, was creeping along a wall and disappeared behind an alleyway. Percy and Sara, being the creepy stalkers they are, decided to follow, simply because they had nothing better to do.
