Hey! So this is how it's going to work, most likely this will be updated daily because I have been writing everything as one big story then splitting it into chapters. Now that it's summer vacation I will have more time to update and write things.

Everyone looked at the girl, she had tanned skin and long dark brown hair. She was wearing a blue dress that went to her knees, with leggings and dark brown boots. She was also wearing wraps on her hands that stopped just before her elbow, on her neck she was wearing a necklace that had a gem with a strange foreign symbol carved into it.

"Uugh, what happened?" the girl moaned. She opened her eyes, her ocean blue eyes. Once she realized where she was they bulged wide and she looked scared and confused.

Barry was the first person to speak.

"Hello" he said nicely

.

" Where am I?" the girl asked.

"You're in Central City." Barry replied.

"I've never heard of it" she said looking around.

"Where are you from?" Caitlyn asked.

"The Southern Water Tribe" replied the girl.

"Can you tell us how old you are and what your name is?" Joe asked from the back.

"My name is Katara and I am sixteen years old. I am a Waterbending Master and a Master Healer" Katara said.

"Does that mean that you are a kung fu ninja master or something?" Cisco asked excited.

"You don't know what bending is? At all?" Katara asked, she seemed surprised as if it was common knowledge. They all shook their heads no. She tilted her head with a puzzled look, her eyes darted around the room, they stayed focused on the cup on the table. She stood up and lifted her arms. In one graceful movement she swirled her hands around, the water in the cup started to rise and go to her. She made it twirl and freeze. with the simplest movements.

"That is called water bending, and this is healing" Katara said as she approached Barry. She moved her hand with the water in it to his cuts from closing the black hole, the water started to glow and in less than a minute they were gone.

"Wow, that's so… AWESOME! What else can you do?" Cisco asked, earning a slap on the arm from Caitlin.

"I can fight with my waterbending. That's it. But that was the fastest I've ever healed anyone." Katara said, examining Barry.

"Oh, I heal fast anyways. I'm pretty fast at everything" He said with a smile.

"How fast exactly?" she asked. Barry smiled wider and flashed to her, picked her up and took her to the outside of Star Labs. He put her down for a minute and she stared at him with her eyes wide in awe. Barry picked her back up and flashed her back to the Coretex.

"That was amazing! Not even Aang can run that fast and he's an airbender!" Katara said.

"Who's Aang?" Iris asked. Katara's face fell.

"He's my boyfriend." she replied sadly.

"Did you two break up?" Iris asked her sympathetically.

"What? No, no. I just don't know if I'm going to see him again. I don't even know how I got here!" she said frustrated, the water started to shake a little as if it shared her emotion. Iris comforted her as Barry turned to Ronnie and Caitlin.

"So, Barry, she came from another universe right?" Ronnie asked. Barry nodded.

"Then how are we going to get her back?" Ronnie asked again. Barry looked at Dr. Stein and he put his hands in the air.

"Don't look at me! I've never had any experience with any of this I had theories" Dr. Stein protested.

"Well, she's going to be here for a while. We need her to blend in as much as possible." Caitlin.

"How are we going to do that?" Joe asked with a "I don't know about this" tone.

"I think I know someone who can help us. " Barry said as he flashed away.
