Note 1: So again, apologies for the lateness of this. Christmas was just madness! I want to let you all know that from now on, I'm going to try something different with Karry Prime: Little chapters! Smaller events, many taking place across the same month, but on a whole leading to a fuller story. This part is just the Barry/Kara aspect of my next time, with Caitlin's being seen to in the next part, and a conclusion for this part next also. Like a 2- or 3-part chapter. It should mean it's easier for me to do on a weekend, so there could be more updates, but only trial and error will tell for sure.

Note 2: I'm also skipping ahead to November to catch us up. No change on events though.

A Grant Mistake.

Late-November 2017.

Another day, another cup of coffee.

Kara was running late as CC Jitters had been packed, and Cat had ordered two coffees this time – The Flash Americano and The Power Girl Iced Latte – without any reason for the second drink. Kara was half tempted to just speed the coffees to the office by the time she arrived at the CatCo building, but decided against it as she waited in the lift.

Walking into the office, finding that packed too, Kara dropped her stuff at her desk, nodded to Iris and then proceeded to Cat Grant's office; a usual routine. It was almost like the memories she had from Kara on Alien Earth, or Earth 3, the routine she went though, if only this was National City, not Central City, and there was no Winn about this time – instead she had Iris.

"I'm sorry for the delay, Ms. Grant, Jitters was…" but she never finished her sentence as her eyes fell upon the handsome man sitting with Cat Grant in her office and instantly Kara's brain was flooded by foreign memories, and yet also familiar.

"That's quite alright, Karen. May I introduce you to my oldest son, Adam?" Cat stood as she took the coffees out of Kara's hands, and handed The Power Girl drink to the man.

"Adam," Kara breathed, feeling herself blush as the man grinned goofily at her. She remembered him, of course, as if from another life. Technically it was another life, but that wasn't the point – Kara Danvers had gone through a lot to get mother and son back together again, and in the process, she had fallen for Adam. Kara Wells had wondered if it could have worked out for Danvers, if it wasn't for James Olsen and Bizarro. The anti-Supergirl had kidnapped Kara while she was on a date with Adam, and with her human identity being targeted, Kara Danvers had decided relationships weren't for her and broke if off with Adam.

Yet she'd still burned a little candle James at that time too, messing it up. That still baffled Kara Wells – even in the memories of James, she couldn't find attractive qualities. In fact, she was sure he had seemed overbearing to Kara Danvers. It made Kara happy to know her Alien counterpart had dropped him easily and was now with Mon-El.

"Karen?" Cat snapped her fingers in front of Kara's face, Kara realizing she had been in a trance, thinking over old memories and hadn't heard a word Cat had said.

"Sorry, Ms. Grant," Kara jumped back into action, moving quickly before Cat snapped her fingers again, for attention.

"I was saying," Cat started a little forcefully, "would you be able to take Adam to lunch? He's only here for a few days and I would, but Eileen and I have a deadline to work to."

"Lunch?" Kara muttered, staring at Cat as if it was a new word she'd never heard of.

"Yes, you know the kind of thing – set between breakfast and dinner, a good fill of food. Maybe a Big Belly Burger? I have been promising him one since he arrived last night," Cat stated.

"Big Belly Burger? Oh, erm, no sorry. Barry and I…" Kara started, remembering that she and Barry had arranged for a lunch date today of all days. That is if STAR Labs wasn't going to keep him as it had the past few weeks. Since the announcement of the app, Mavis the other month, not to mention Palmer Tech shifting some of their research to the Labs, work was picking up for Barry and Harry – the latter was really enjoying it, it reminded him of life on his home Earth; but for the former, for Barry, it was a learning curve.

Still, it was apparently better than being a CSI.

"Shame," Cat spoke up, "but I suppose for the better. I'm sorry Adam, but you'll be on your own. I could order something in, you can eat in the office?"

"No mom, it's fine. I want to go out regardless, have a look at Central City, see what all the fuss is about. Maybe get an eye on Power Girl," Adam pulled a little goofy grin at that as Cat chuckled.

"He's got a thing for Power Girl, you know," Cat turned back to Kara, surprising her. "Finds her very attractive." There was a look on Cat's face that Kara couldn't quite place. Almost a knowing look, but Kara wasn't sure why or what for, her mind was still on Adam and his apparent obsession with her alter ego.

"I gotta go…" Kara breathed. "I mean, I have to do some… stuff… to do. Nice meeting you Adam," Kara nodded at the man and his mother before leaving the room, almost tripping over the waste paper basket as she did so.

"Woah there," Iris called as she grabbed on to Kara to stop her from falling and making a scene. "You okay?"

"Yeah, thanks," Kara muttered distractedly as she found her footing again.

"You sure? You look like you've seen a ghost," Iris stated as she moved with Kara to her desk.

"Close to. An Ex. Well, a sort of ex. Adam," Kara stated turning towards the office again eyeing the man.

"You dated Adam?" Iris hissed, wondering when that could have happened as she turned to look back into Cat's office to see her having her coffee with Adam, laughing and smiling. Kara looked back too, surprised at how entirely different this Cat and Adam relationship was compared to the relationship Kara remembered – although Cat's history with her son was very different here.

"Well the Kara on Alien Earth dated him, I mean. I have her memories and… it's confusing," Kara admitted, taking a seat now.

"What about Barry?" Iris asked.

"What about him?" Kara questioned, raising her eyebrows. She couldn't see how Barry fit into her memories of Alien. "Kara Danvers dated Adam long before she ever met Barry."

"No, that's not what I mean." Iris said with a chuckle at the innocence Kara was displaying, she not understanding what to do when you bumped into an ex-partner. "Are you going to tell him?"

"What's there to tell?" Kara shrugged, turning on her computer now.

"The whole other relationship!" Iris persisted.

"There's no other relationship. Not here. That's Alien Kara thing. It's all very one-sided," Kara muttered. "This Adam isn't the same. He doesn't know. He may be obsessed with Power Girl, but we've never dated. Nor will we. I'm with Barry, that's all there is to it."

"Wait, Adam's obsessed with Power Girl?" Iris looked back through the glass pane into Cat's office, a frown on her face.

-Power Girl-

Kara sat back in her chair, annoyed as she got off the phone. She had to control herself not to break the chair as she sat back, or the phone as she slammed it down back on the receiver. She looked up; Iris and Cat had already left, and half the office was empty now with people gone to lunch – she'd hoped she'd be one of them, sitting across a table from the handsome features of Barry Allen as he grinned goofily at her in between bites of whatever food they'd decided to have this day.

"Bad new?" Kara looked up to see Adam leaning against the doorway to his mom's office, an equally goofy grin on his face now.

"It's nothing," Kara said not wanting to get into it with Adam.

"Doesn't seem like nothing," Adam persisted.

"It is. Lunch date fell through. He's busy at work," she muttered briskly, looking away from the man to focus on her computer. She didn't want to go into details. She didn't want to explain that her boyfriend ran a business now and that was what was taking him away from her. Again.

"Come on, we'll go out," Adam stated cheerily.

"What?" Kara asked, aghast.

"You, me, we go out. I have nothing planned, you have no more plans. We can make a date of it," he moved over to Kara's desk now, leaning on it so much like his mother did.

"No," Kara moved back in her chair, remembering Adam from the other Earth again. He was just as charming.

"Oh come on, just because one person bailed on you doesn't mean you can't go out with someone else, there's no law against it. Unless you're worried the boyfriend will be jealous?" Adam stated.

"Barry's not the jealous type," Kara stated, Adam now moving to perch on her desk.

"Go on. One meal, then we come back here, all innocent. Barry need not know," Adam stated, leaning closer to her. She forgot how perfect his strong jaw was, how blue his eyes were…

"Fine. Big Belly Burger," Kara sighed, knowing she wasn't going to get away from him so easily.

"Good," Adam said with a smile, standing back now, a curious look on his face. "By the way, I have been meaning to ask: Is it Karen or Kara?" Adam had heard other people in the office call her Kara, yet his mom called her Karen. He suspected one was the correct name, but had to make sure.

Kara paused as the memory of the other Adam asking almost the exact same thing came to her mind. She even replied the same way Kara Danvers did almost on instinct, smirking, "It's Kara to everyone but Ms. Grant."

"Ah," Adam said, nodding. "She's still doing the wrong-name thing." He shook his head, knowing his mother too well by now. "You know, she always hired a personal chef to cook for me and Carter and for events she hosted, but with calling out the wrong name and constantly changing her mind on what to make the, chefs always quit. I swear you'd have to be The Flash to keep up with mom demands."

Kara chuckled. "I don't know if The Flash cooks," She said as they exited. Seemed if STAR didn't work out, Barry could always take up catering for Cat.

-Karry Prime-

"Kara?" Barry exited the lift to the office of CatCo, not able to speed in in case it gave away his identity, but he had been able to get off work for a little while; he hoped it would allow him some time with Kara as she hadn't sounded impressed with him when he'd had to cancel on her.

"She's out," one of her colleague replied, as Barry moved across the office. He paused as he looked at the colleague.

"Oh. Did she say when she'd be back?" Barry asked, glancing to Cat's office and Iris's desk, finding both empty.

"No, but she went out with Adam Grant," the woman stated simply.

"Who's Adam Grant? Relation to Cat?" Barry asked, unaware of the man himself.

"Ms. Grant's son," the woman stated simply, moving off now as Barry stood alone on the office floor.

"Cat's son…?" Barry muttered. "Kara went off with Cat's son?" His mind was racing over the facts; he knew about Carter, of course, and had heard that Cat had an older son, but nothing else. How much older than Carter was he? Should he be worried?

As he moved back to the elevator, a little faster than humanly possible, the doors opened, and he paused at the sight of the four people within: Cat Grant, Iris, Kara and an unfamiliar man. That must be Adam. He frowned.

"Barry?" Iris asked, a cocked smile on her face.

"Mr. Allen, I thought you weren't available for a date with Karen," Cat now spoke up as Barry tried to figure the words to say. His eyes remained on the only man in the elevator as the four occupants left.

"Why are you here?" Kara now spoke, splitting from the group as she dragged him aside to a side room. He was still looking at the taller, handsome man moving into Cat's office with the boss, visible through the glass panes. Cat liked her glass dividers.

"I managed to get some time away…" Barry muttered, forcing himself to look away from the office and at Kara. "You went out with him?"

"He insisted," Kara stated, waving it off. "We went to Big Belly Burger, met up with Iris and Cat on the way back. Nothing important."

"Nothing important? You went out with another guy!" Barry stated, flummoxed by this.

"He's Cat's son. I've gone out with Carter before," Kara pointed out, annoyed Barry was getting upset over this. She was glad he didn't know her memories of Adam though.

"He's twelve," Barry pointed out.

"Fifteen, nearly sixteen, actually," Kara corrected.

"Whatever. The point is, you went out with another guy, on a date, when we're meant to be an item," Barry's waved his arms about manically at this, as if to prove a point, and Iris was moving over to see what was up.

"Barry, calm down," Kara insisted, she could feel his annoyance but didn't understand it – it wasn't a date, and he couldn't see that. "You cancelled on me, he offered to take me out. I said no at first anyway, but then…"

"Then…?" Barry interrupted, expectantly.

"Well, a girl has got to eat," Kara said simply. "And it wasn't a date. Just two friends going out. What's your problem? Why are you overreacting?" Kara persisted as Barry took breath.

Maybe he had overreacted? STAR was keeping him busy – he had barely gotten any sleep recently, and the meetings were driving him crazy. He had barely been able to be The Flash or just run lately. If it wasn't thanks to the Speed Lab Cisco had added below the Cortex, he'd have no chances on taking a quick run. Honestly, he had no idea how his Karry counterpart did this, while being The Flash, and having two kids. Maybe he had just taken a little stress out on Kara just now?

Before he could apologize, before he could say he was overstressed, Iris came in, concerned for the couple. "Barry, Kara, everything okay…?" Iris asked. Kara looked to her friend, a little helpless. Maybe she could explain to her why Barry was getting so upset about this?

"Barry's getting upset because I had lunch with Adam," Kara stated levelly. "It was just lunch," she added.

"Barry," Iris grabbed Barry's arms now, forcing him to look at her, believing she could get the situation under control. "Adam is her boss's son. It's not like she could say no. Besides, it's not like he's her actual ex here."

"What does that mean?" Barry asked, suddenly confused by the expression. "Her actual ex?" He turned back to Kara, who now felt her heart plummet, and she began to realize exactly why Barry might get upset. She'd never had any exes, at least no real ones, being a clone made over a year ago – hell, Barry was essentially her 'first' – but she knew how tricky things could be in relationships when an ex-partner reared their face. Was this such a situation?

"He didn't know…?" Iris said, pointing at Barry and seeming worried she had spilled information to him.

"I… um…" Kara spoke up, glaring at Iris now. "The me I got my memories from… Before you turned up on that Earth… I, that is to say, she… she had a date or two with Adam. It didn't work out because she was kidnapped and was sort of obsessed with James at that point, but Adam Grant is sort of… well, he could be considered an ex, but he doesn't know." Kara bit her lip at this as Barry's eyes widened. "But this wasn't a date," Kara insisted. "You're my boyfriend. He's nothing but my boss's son."

"No… no, I get it," Barry muttered, taking a step back. "I should have seen this coming. It's your memories, your reason for living."

"You helped me get those memories!" Kara said suddenly defensive over it. "And you knew Kara Danvers wasn't living like a monk. Didn't you convince her to go for James anyway? I still don't understand why, since he was a jealous ass when you were there for no reason." Kara realized now might not be the best time to argue, but she couldn't stop herself. "You can't get upset over a boyfriend that was not mine. Are you going to get upset if I bump into Kara Danvers's friend Kenny, who she had a crush on in high school?" Kara remembered the boy who died on Alien Earth; one of Kara Danvers' first loves.

"Kenny?" Barry muttered, confused.

"Or what about Winn?" Kara continued. "Did you know Winn had a thing for Kara Danvers? Should I stay away from him too?"

"No. It's just…." Barry seemed to have no answer for this. "I got out of a meeting to take you out Kara," Barry mumbled a little lamely. He couldn't look at her. "It was an important meeting too…"

"I'm Power Girl, not psychic!" Kara hissed, careful to keep her voice low at this point though. "How could I tell you were going to get out of that meeting? You called and said our date was cancelled. Look Barry, Adam means nothing to me. You're my boyfriend. I love you. Can you just get over this?" Kara asked, going to put a hand on Barry's shoulder but he flinched away.

"I need to run." Barry said monotonously, knowing he needed to clear his head. He needed to think this over. Kara had some good points, but he couldn't help but feel betrayed.

"Run?" Kara asked, worried now. "But you just got here."

"Running clears my head," Barry stated. "I need to think."

"What's there to think about?" Kara asked, her voice a little hollow, she unable to think herself.

"I just need to think, okay Kara? See you later," Barry turned and left the room at that, but Kara didn't want it to stop there.

"Wait, Barry…!" She tried as Iris watched on, but Barry didn't turn back as he reached the staircase – she knew he was going to speed down it then take to the streets. "Barry," Kara tried again, but felt a hand around her arm. She looked back to see Iris had ahold of her.

"Leave it," Iris muttered. "When he gets like this… just give him time. He'll come around."

"But what if he doesn't?" Kara turned back to Iris now. "What if I just screwed this up because I went to lunch with another guy? It's not like I wanted to go." She felt so lost now. "Should I talk to another Kara about this?" She lowered her voice as she said this, being back in the main floor. "Maybe Karry's Kara did something stupid in college, or that Twin Earth Kayla who's going out with Barry…?"

"This isn't a multiverse issue," Iris muttered back, shaking her head. "This is a you-and-Barry-only issue. Like I said, give him time, he'll come around. I'm sorry I brought up your other past." Iris put an arm around Kara's shoulder. "You made some good points though. Maybe you should have shot him a text, saying you were going out with Adam, but I mean it's not like you get jealous every time me and Barry hang out."

"Why should I?" Kara asked finding that sentence odd. Barry and Iris were siblings. Shouldn't she get more jealous over Caitlin than Iris, since they were not family?

"Because… He had… We… You know, what never mind," Iris stumbled, seeing Kara didn't know about the long time Barry was in love with her and how Iris had confessed her love back to him at one point, just before Kara had showed back up. The two had moved on from it though, and now it all just felt weird she could have almost ended up with her brother.

Kara ignored the comment now, feeling helpless. Barry was already gone, and she didn't know where to catch him. Should she take to the air, see if she could see that streak of red that was Barry and stop him, force him to talk?

"Karen?" Kara looked around. Cat was by her office door. "Everything okay?"

"Yeah," Kara stated a little quietly. Iris was already moving to her desk.

"Good. Adam was wondering if the three of us should go out for drinks tonight? I think it's a fantastic idea, but with Mr. Allen…?" Cat queried.

"So long as you're there," Kara stated, a little forcefully as she glanced to Iris by her desk now. It wasn't like her boss was giving her any option.

"Excellent. Now, this afternoon I'll need to look at the draft of the December issue. Can you call the editorial department to make sure they're all setup for that?" Cat was instantly back in business mode.

"Sure," Kara sighed, moving back to her own desk now. She tried to think on for what Barry was thinking, trying to focus her emotion on him, but their bond wasn't anywhere near as strong as that of Karry. All she felt was confusion and she couldn't tell if it was Barry's or her own.

Had she really messed this up already?

Next Time: After a run in with Jessica Cruz, Caitlin's meta human powers start to properly manifest, but Caitlin doesn't want to be Killer Frost. Can Team Flash figure a way to stop the transformation before it's too late? And what about Kara and Barry's relationship? A night out with Cat and Adam may not be the best answer.
