Mergence

Disclaimer: Frankly, I loved the Supergirl/Flash crossover a great deal to the point I got to thinking about a few things that eventually led to this. Oh yeah, I don't own anything but what you see here!

Summary: Barry winds up getting a chance to meet Kara again in an entirely unexpected way.

When Barry woke up that morning the first thing he realized was that something felt off. He was somehow in another bedroom that wasn't his own and there was someone in the bed with him. Which made him worried as he turned his head to see who it was with a frown on his face. And to his complete shock the other person was none other than Patty Spivot's lovely self! Gaping at her like a fish, he quickly got out of bed in a hurry but was then brought to his knees as memories flashed through his mind's eyes. Giving him the astonishing revelation that he now had two sets of memories in his head! The second set of memories told him that rather then Kara 'Supergirl' Danvers and her world being another Earth, her world simply had always been part of his. These new memories also showed that things had gone on a much more different path regarding him and Patty as he'd come clean about a few things in her apartment when she had confronted him when he showed up.

Which he wasn't exactly bothered by this as he had been missing Patty terribly since she had left for CSI training. Sure, he could always speed over and see her but life had been keeping him annoyedly busy that he hadn't had much time to get a chance to go and see her. So however this merging of the worlds had happened, Barry could definitely accept it! His new set of memories also told him that he and Supergirl were considered to be 'The World's Finest' after a few team ups they had together. The first being when they fought against Livewire and Silver Banshee roughly four months ago in the new and changed timeline. His fall to the floor had woken Patty up from her sleep and she rushed over to him in concern. "Barry! Are you okay!?"

Looking at her with a wide smile on his face, he quickly told her that he was more than okay and that he'd just simply fallen out of the bed in his haste for a quick rush to the bathroom. Something that got him a chuckle from her as she kissed him on the forehead in relief. "As an officer of the law Mr. Allen, I am going to need you to be more careful okay?" She told him in a teasing voice.

Barry just laughed and saluted her. "You got it Detective." Responded the Speedster cheekily and making her roll her eyes at him.

She leaned in and kissed him on the lips, an action he savored a great deal and kissed her back. Pulling away she climbed into bed now that she knew things were okay, Barry looked at her for a moment before realizing that he actually did need to use the bathroom. Go figure a white lie would be a real thing. Groused the Speedster in his head and he rushed off to take care of that while Patty made herself comfortable in their bed.

Once his business was taken care of, a knock on the front door was heard and he went to it while wondering who would be showing up here pretty late at night. The person on the other side of the door surprised him a lot as it was none other then Kara herself! "Please tell me you have two sets of memories Barry!" Spoke up the girl in an alarmed tone of voice as she came inside.

"Yeah, actually I do and I'm guessing that like me you have no idea what happened either."

"Pretty much."

"I guess this means neither of the two of us will have to make some crazy device to show up in the other's world now." Joked Barry and earning himself a laugh from Kara in the process.

He was going to ask how she even knew he was here but the Speedster figured her X-Ray vision probably clued her in. Which… Probably allowed her to see some things she probably didn't want to be seeing! "I guess so!" Kara finally said.

To be honest, she was happy about this as she had liked being around Barry and now that their worlds were somehow merged their budding friendship could continue on without the multiverse being in the way. "Barry who's… Oh, hey Kara!"

"Hey Patty. Sorry if I woke you guys up." Replied the girl in a sheepish tone.

Patty smiled at her as she slid an arm around Barry's waist while he put one around her shoulders. "Oh no, not at all. Barry here already had us both awake anyway."

Barry for his part just stuck his tongue out at her for her teasing. "Well I better get going as you two probably want to get some more sleep."

Kara walked back towards the front door and Barry opened it up for her with a smile on his face. "See ya Girl of Steel."

"See ya Scarlet Speedster." And with that, she was gone.

Walking back to his girlfriend, he put his arms around her as she did the same to him around his neck. "You know what I'm thinking about right now?" Asked Patty with a grin on her face as she looked into his eyes.

"Hmm… Knowing you that might be anything from the latest Science article to what to eat on Friday." Joked the Speedster and Patty rolled her eyes at him before biting his nipple through his shirt.

"Not even close mister."

She pulled away and giving him a look, she ran towards their bedroom and Barry just grinned and sped off. Making for a fit of giggles to erupt from Patty in the process too once he got pretty handsy with her. Later on after some well earned rest, Barry and Kara would come to learn that only Cisco, Harry, Caitlin, James, and Winn would really even know that something was different. Though why the five even remembered was anyone's guess but Harry figured it might have something to do with some form of exposure from Barry due to his traveling through dimensions and time itself. But since it wasn't seeming to be a danger it wasn't explored much and they all went about their lives, happy as can be with this change of events.

Author's Notes: I am probably going to come back to this at some point in a future update or as a story. No telling with my thinking. Anyways, hope you all enjoyed! R and R!
