This is a new Flash and Supergirl crossover brought to you by me and my friend, Knight2000. What if Iris wasn't Nora's REAL mother? What if Nora's mother was someone else and Iris (in the future) took Nora away after Barry went into the Speedforce?

Wanna know who the real mother is? Read on to find out!

Nora's diary (speed language):

I'm thinking about something that I shouldn't but with my events from my past/future, I started to think about this: is my mom really my mom? My father was/is a speedster aka The Flash and she supported him but when I reveal to her my powers, she tried to stop me from using my powers. Shouldn't she support me instead of trying to stop me? When I became XS, I started to think about if she was really my mom but then I decided to forget about it. Who else would my dad be with?

End of diary.

S.T.A.R Labs:

Nora was in the Speed Lab thinking about her time in the future with her mom: all the arguments and the speed damper that she was holding. Nora knew that there was something wrong with the relationship but thought it was down to lack of a father so she just ignored it, Nora decided to suit up into her XS suit then went for a run and she took her diary with her. In the corridor, Caitlin caught a glimpse of a speeding Nora running towards the exit of the building.

Meanwhile:

Barry was in the Cortex looking at the Flash Ring then thought about having his daughter with him: he was happy to see Nora and that he was spending time with her. But what bothered him was all the things Nora said Iris did especially like sticking a speed damping device inside their own daughter: did Iris really have a good reason for putting it in Nora?

"Barry, everything okay?" Barry turned around and saw Caitlin walk in with some paperwork. "You look like there's something bothering you." Caitlin pointed out, Barry nodded then sat down in a chair near one of the desks in the corner.

"It's something that Nora said about Iris," Barry started, Caitlin put the paperwork down then pulled up a chair and sat opposite Barry. "Nora said Iris did whatever she could to stop Nora from being who she wanted after she got her speed." Barry told Caitlin who looked surprised. "Would Iris do that and if she did, what was the reason behind it?" Barry asked, Caitlin shrugged her shoulders then looked at her best friend.

"Honestly Barry, I don't know what to say," Caitlin said as she held her best friend's hand.

"We don't know what could've made Iris put that dampener inside Nora but there has to be a reason." Barry nodded then two sat there waiting for the rest of the team to come in but then a gust of wind blew in, the pair turned to see Nora stood in the doorway.

"Dad, could I use some of your lab gear?" Nora asked which confused Barry. "There's just something from my year that I want to check and I was wondering if I could use my time here to check it." Barry stood up and nodded but not before hugging his daughter.

"Go ahead," Barry smiled which made Nora happy. "But Nora, could we talk later? Just us?" Barry asked and Nora nodded then she ran off to get her Dad's lab gear while Barry and Caitlin stayed in the Cortex and talked about Nora.

Speed lab:

After getting her Dad's lab gear, Nora used her gauntlet to scan both her own and her mom's DNA then imputed into the computer. She wanted to check if her brain were playing tricks on her or not so Nora pressed the scan button: the computer began scanning both sets of DNA and during that time, Nora was getting tired of waiting. After a long period of waiting and running around the room, the DNA scan was finished so Nora decided to check the results but she got the shock of her life.

"Not a match?" Nora mumbled then she decided to repeat the DNA testing and after repeating it several times, the results didn't change. "Iris isn't my mother?" Nora was shocked then she decided to run Caitlin's DNA against her own. "Still not a match?" Nora fell into the chair behind her as she was shocked: neither Iris or Caitlin was her mom. "If Iris isn't my mom and neither is Caitlin, then who is?" Nora asked, she thought she was alone as she looked back at her's and Iris' DNA results but then she heard footsteps coming towards.

"Nora?" The voice belonging to Iris West-Allen and she looked worried. "Nora, are you alright?" Iris asked as she walked towards her, Nora shook her head then got up and looked at Iris.

"I don't know anymore!" Nora screamed then blasted off, Iris walked towards the computer screen and saw what bothered Nora: it was the DNA results.

"What? Me and Nora aren't related?" Iris asked herself as she looked at the doorway where Nora had just ran out of. "How is this possible?" Iris decided that Barry had the right to know about this as it seemed that Barry was 100% Nora's biological father.

Meanwhile:

Nora was running so fast that she had broke the dimensional barrier and was running through the Multiverse until she ended up on another version on Earth. Nora looked around until she saw a statue of a flying woman and knew who she was thanks to the Flash Museum.

"That's Supergirl which means…" Nora took a few steps into the busier part of the city and there was Worldwide Media. "I did it. I broke the barrier and traveled to another Earth. I wonder if I could meet Kara Danvers." Nora looked at her clothes and it was lucky that she was wearing dark blue torn jeans with black trainers, a white t-shirt and red checkered shirt whilst carrying a backpack. Nora decided to head over to and see if Kara was there but then saw a flying figure crash into a wall and after the dust cleared, Nora saw that it was Supergirl and she was fighting some kind of robot with a green light in the chest. Supergirl flew back and fought the robot while Nora ran down an alleyway and quickly changed into her XS outfit.

Concurrently:

Supergirl was getting beaten by Metallo thanks to the Kryptonite power source in its chest, she thought Metallo was going to hit her again but from out of nowhere, a streak of pink and yellow lightning flew past Supergirl and struck Metallo's systems: causing him to short circuit and fall down to the ground. Supergirl looked behind her and there stood a female dressed in a black and white suit with pink and yellow electricity sparkling off her, the figure walked over and offered Supergirl a hand up who took it to get off the ground.

"Thanks for that," Supergirl smiled as she dusted off herself off. "Who are you? Are you related to The Flash?" She asked, the female nodded then they walked down the same alleyway she came out of until no one could see them. The heroine removed her mask so that Supergirl could see her entire face.

"I'm Nora, I'm Barry Allen's daughter from the future," Nora introduced herself which surprised Kara. "Sorry to shock you, Miss Danvers." Nora apologized but Kara smiled and patted Nora on the shoulders.

"It's fine, Nora," The two heroines walked down the alleyway and there in front of them was Kara's apartment block. "It's not the first time I met someone from the future: I once met my ex boyfriend but he was from the future." Kara told Nora, they both got up to the open window of Kara's apartment their way: Nora ran up the building while Kara flew up.

Earth-1:

Meanwhile Barry was sat in the medical bay as she had just got the news that Nora wasn't Iris' daughter but she was still his. Barry was trying to figure out what to do concerning him, Nora and Iris but that was put aside when Joe walked in and he was looking around.

"Barry, what happened?" Joe asked, he sat down next Barry as his son was looking at a photo of himself with Nora and Iris.

"Nora did a DNA test which she told me it was for a case, but she lied," Barry told Joe who was shocked. "However the DNA test was comparing her DNA alongside Iris." Barry told Joe then he showed Joe the test results.

"Are these true?" Joe asked, Barry nodded. "So Nora and Iris aren't even related? Then who is Nora's mom?" Joe asked and Barry nodded.

"Joe, I don't know who else could be Nora's mother," Barry admitted and Joe nodded as he patted his son on the shoulder. "And now, Nora's disappeared and I don't know where she is." Joe didn't know what to say because he was speechless: Iris wasn't Nora's mother, Barry was emotionally confused and now Nora was missing.

Earth-38, Kara's apartment:

Nora and Kara were talking about Nora being from the future and that he doesn't have her dad. Kara felt sorry for Nora so she hugged, Nora smiled then hugged Kara which made Nora feel very happy then they sat back and drank their cup of tea.

"This is so schway; I'm sat here with the legendary Supergirl and I know her identity!" Nora exclaimed which made Kara chuckle. "I've always wanted to meet you, Kara." Kara smiled then she got up and walked over to the fridge to get some donuts, meanwhile something inside Nora made her to scan Kara's cup which made her prints then run her DNA against her's.

"I doubt that my biological mother is Supergirl," Nora thought to herself, Kara was about to walk back over but her phone rang which gave Nora more time with the DNA testing. It didn't take too long for the results to come through. "What?" Nora was now emotionally and mentally confused at the results.
