(y/s/n) = your son's name

(Y/N) could feel a pair of eyes burning a hole through the side of her face. It made her uncomfortable, but she had a feeling she knew what it was about. She set her pen down, lifted up her bowl of cereal and turned to look at Caitlin, who looked like she wanted to say something.

"What?" (Y/N) questioned Caitlin, snapping her out of the trance state she was in. Caitlin tapped her fingers along the desk, contemplating whether she should tell her or not. (Y/N) put a spoonful of cereal in her mouth and waited.

"I still can't believe you slept with Barry," Caitlin blurted, not giving (Y/N) enough time to prepare.

(Y/N)'s eyes widened mid bite causing her to almost choke on her cereal, but she couldn't resist answering. "Oh my god, Cait! That was like a month ago," (Y/N)'s mouth was full, but she covered it with her hand.

"I know, I know. But still, isn't it weird seeing him everyday?" Caitlin wasn't asking to patronize her, she was sincerely worried about (Y/N). "I mean your... your eating your weight in cereal!"

(Y/N) gasped in an offended manner, "I'll have you know, this is good cereal. Plus, it was only one night, it's not like we're in love or anything," she put another spoonful in her mouth, and smiled at Caitlin, who promptly rolled her eyes. "Your eyes tell a different story," Caitlin turned away, but could see (Y/N), from the corner of her eye, look down as her face turned red.

(Y/N) wasn't in love with Barry... Or was she?... No, she and Barry were just friends and they only slept together because they were both in a vulnerable state after the whole Reverse Flash incident. (Y/N) had to clarify to Caitlin that things between her and Barry were purely platonic.

But before (Y/N) could say anything else, Barry and Cisco walked in. "(Y/N), isn't that like your fifth bowl of cereal?" Cisco pointed at the bowl and narrowed his eyes at (Y/N). She dropped her spoon in the bowl, and stood up to face Cisco. "Third. And what is it with you and Caitlin and me eating cereal! Leave me be!" Cisco and Caitlin laughed, "God, (Y/N), so dramatic." (Y/N) tried to be serious, but she couldn't resist laughing at Cisco's smug face. "Shut up," she giggled and pushed Cisco playfully before turning around to hug Barry, "Hey, Bare. You gonna say something about me eating cereal too?"

Barry laughed, "No, actually, I think I know what I'm gonna buy for Christm-" Barry was interrupted by a sudden gust of wind and a loud crash in the room where Barry's treadmill was. Everybody stared at each other in fear, and (Y/N) was the first to speak up, "What the hell was that?" Barry looked at (Y/N), and sped past everyone into the room. A few seconds passed before he came back out with a teenage boy. (Y/N) gave Barry a questioning look, "Another speedster?" Barry shrugged, and the boy had yet to say anything.

"Sit him down," (Y/N) sighed, rolling out a chair and pushing it towards Barry and the boy. The boy sat down and looked up at Barry and (Y/N), who was still eating her cereal, "Mom? Dad?"

(Y/N) looked at Barry, confused, "Excuse me?" Barry scoffed, "(Y/N), you never told me we had a son!" She smirked and smacked his arm, "Don't be stupid," she looked back down at the boy, "What's your name, kid?"

"(Y/S/N)."

"OK, (Y/S/N), what are you doing here?" Barry pushed (Y/N) behind him in a protective way. She sat back down, finishing her cereal, and watched the interaction between Barry and the boy.

"God, Dad, still protective as always."

(Y/N) burst into laughter, and Barry frowned at her, "Yeah, Dad, why you gotta be so protective?"

"And you, Mom, stop eating so much cereal, that's why I was so big when I was born." (Y/N) stopped laughing, her mouth hanging open in shock.

"Ok, ok, what is this 'Mom and Dad' crap? I'm only, like, six years older than you. And what is it with everyone and me eating cereal, dammit." Barry was laughing silently behind Cisco, and (Y/N) glared at him.

"I'm your kid- well, future kid- and I traveled back through the timestream to warn the both of you-"

"Warn them about what?" Cisco chimed in, not letting the boy finish.

The boy smiled, "Same old Cisco. About something that my mom and dad will do sixteen years from now that results in their death." This caught (Y/N)'s attention. She stood up quickly from where she was sitting, and sped walked to where the boy sat.

"You said what? Death?... You said I was your mom?" The boy nodded. "And Barry your dad?" Again, the boy nodded. She eyed Barry, who seemed just as interested, and raised her eyebrow at the boy, "When were you born, kid?"

The boy thought, "Well, seeing as you're eating so much cereal right now, I'd say I traveled back to when you were pregnant with me, and since this year is about to end and you're not showing yet... next year... from now, of course." (Y/N) went cold, all color draining from her face. She shook her head at his statement.

Barry watched (Y/N) as she was starting to panic and he turned back to the boy, "Kid, watch your words, is what you're saying true? Are we really your parents?"

He nodded and stuck out an arm, "Aunt Cait said you probably wouldn't believe me, so she told me to tell you guys to do a DNA test."

Caitlin's eyes widened, "Aunt Cait? Me?"

"Yeah, you. After my parents died, you took me in. Then two years later, helped convince me to come back here." Everybody stared at him, and (Y/N) groaned.

"What happened to us?"

The boy huffed, "It was bad. Aunt Cait and Cisco always said you died a death you guys weren't meant to. And the worst part was you didn't die as The Flash, you died as (Y/N) and Barry Allen."

"(Y/N) Allen... are you saying we're married in the future?" Barry blushed at the thought of him and (Y/N), the girl he was in love with, married and with children.

(Y/N) inhaled deeply and furrowed her eyebrows, "But the newspaper. It said Iris West-Allen. I thought you were destined to marry her-"

"Some things are predetermined, yes, but things can change. Nothing is written in stone, you always told me that." The boy raised his eyebrow, and smiled at her.

"Whoa. He just did the eyebrow thing like you (Y/N)." Cisco seemed amused by this whole situation.

(Y/N) shot daggers at Cisco, who immediately stopped laughing and became serious again.

"Kid, how did it happen?"

"Well, knowing dad, he heard screams coming from a burning building and sped past everyone to save whoever it was, but unfortunately he got pinned down by debris, and mom, stubborn as always, ran into the building to help him," the boy exhaled deeply and continued. "Both of you realized that there was nothing you could do to save dad. He couldn't use his arms to fan out the fire, he couldn't use his speed to free himself, and mom got injured when she was running in the building and she didn't want to leave Dad, so she laid down next to him. You guys spent your last moments together before the building came down on both of you."

Barry looked down, and (Y/N) stepped closer to him. The thought of her loving Barry so much that she would die for him made her heart beat so fast she thought it was going to rip through her chest. Barry looked at her and smiled, then looked back at the boy, "Maybe if I did it differently. What hallways did I go through? I'll go through different ones this ti-."

The boy shook his head furiously, "That's not the point. They only found two bodies in the rubble, yours and hers. There was no one else, they tricked you! You died for nothing! Left me, Cisco, and Caitlin alone!" (Y/S/N) was starting to tear up, but he wiped it away. "All I'm saying is that sixteen years from today, when you guys are coming back home from your dinner date, DO NOT go in that burning building."

Once the last syllable left the boy's mouth, he stood up and kissed (Y/N) on the top of her head then sped past everyone, through the timestream once again, leaving everyone speechless.

(Y/N) scoffed and cocked her head to the side slightly, "I don't know if I believe him or not."

"Well there is one way to be certain," Caitlin smirked, looking at (Y/N).

After almost half an hour of Caitlin trying to convince her, (Y/N) finally agreed to an ultrasound. She was laying down on the bed, while Barry and Cisco stood next to her. Caitlin put the cold gel on her stomach, causing her to flinch a little. When Caitlin turned on the monitor, everybody gasped at the sight.

"Holy shit. He was telling the truth." (Y/N)'s eyes brightened up, but she couldn't lie; she was terrified.

"You mean that little dot right there..." Barry leaned closer to the monitor, pointing. Cisco slapped his back, and chortled, "Yep. That's your kid."

Barry laughed, and looked down at (Y/N), "You sure he's mine? I mean-"

She slapped his shoulder , "Don't be stupid. You're the only one I've slept with in the last six months."

Everyone laughed and looked back at the monitor, "That's (Y/S/N)." But then (Y/N) suddenly went cold. Barry noticed her unexpected change in mood, and put his hand on her cheek, "What's wrong? Are you OK?"

"He's... He's a fucking speedster," She looked up at Barry, eyes wide. Barry was confused as to why this scared her, so (Y/N) clarified, "He's a speedster Bare, do you imagine what it's going to be like when he starts walking?" Barry let out a breathy laugh, and kissed (Y/N)'s forehead, "It'll be fine, we'll teach him."

"From what I could tell, you raised him well (Y/N)," Caitlin smiled at her and Barry. Cisco came up from behind and agreed with her, "I'm sure you guys are gonna be great parents."
