It was a beautiful day in Central City, and Barry was late, yet again, to meet Iris at Jitters for their normal coffee meet ups. It seemed like no matter what he did, the universe was determined to make him late at every turn, and today was no exception (Barry: 0, Universe: approximately 3 million). He was sure he could picture Iris shaking her head as she glanced at the time, already accustomed to his lateness after years of putting up with it and teasing him about even being late to graduation.

Barry speed walked across the street, the Jitter's door only a few seconds away, when he bumped into a brunette just coming out, spilling some coffee on her white shirt.

"I'm so sorry!" Barry said, trying to grab some napkins from his bag to help her clean up.

"Shoot," she muttered, "it's fine."

She had dabbed as much as she could with the napkins trying to get the stain out, when she finally glanced up at him.

Barry looked into the hazel eyes staring up at him, recognition dawning on him.

"Caitlin?" he asked.

"Barry? Wow, it's been a while," she exclaimed, both of them moving in for a hug.

"I haven't seen you since what, kindergarten? First grade?" he asked.

"Yeah, some time around our debut as a couple, remember?" she asked.

Barry smiled, remembering the times they used to play together during recess. He remembered overhearing his parents talking about a couple being boyfriend and girlfriend, curiosity peaking his interests.

"Do you know what a couple is?" Barry asked.

"It means two," she said.

"But isn't it when you have a boyfriend or girlfriend?" he asked.

"You mean like our parents?" she asked.

"Maybe. Does that mean we get to drive a car and do what they do?"

"I think so," she said, her forehead scrunching a little in confusion. "Maybe it's like playing house but for real."

"Then let's do it! Will you be a couple with me?"

"Uhm, okay!" she said.

Barry brought himself out of his memories, shaking his head a little and smiling while running his fingers through his hair. Back then she had been a little girl with short brown hair. Now she'd grown up, her hair wavy and dark, her eyes deep and just overall beautiful.

"So, what have you been up to? I never heard from you again after your parents moved," he said.

"I have a job over at S.T.A.R Labs actually. I'm working with Harrison Wells on his particle accelerator. It's set to open in a few weeks and we've had meetings for it constantly," she said, and although she looked a little stressed, she also looked happy to be a part of it.

"That's amazing, I can't believe you get to work with him," he said.

"You should come by some time," Caitlin said, "before everything gets crazier. I'll give you a tour."

"Yeah, that'd be awesome," he said.

Barry suddenly remembered that Iris was still waiting for him, and he was even later than ever.

"I have to get back," Caitlin said, beating him. He was even late in his goodbyes today.

"It was great seeing you," he said, bringing her in for another quick hug.

"You too," she smiled, pulling her hair behind her ear, a ring on her ring finger. She was engaged.

Barry wasn't sure why, but that surprised him. He felt slightly disappointed, if only for a moment, before he smiled one last time and headed into Jitters.

What he didn't know, was that a few weeks later, he would get more than just a tour from S.T.A.R. Labs, and both Barry and Caitlin's lives would change forever.
