A/N: Holyy... Have I missed y'all, it's great to be back... I missed my terrible writing skills, I truly did miss 'em... Without further ado, let's get the excuses rolling shall we? (Excuses at bottom of DESC)

DISCLAIMER: I do not own the flash, I only own my stupid ideas :)

Caitlin's House

"Ugh... What happened?"

Caitlin just woke up for the first time after last night's events at 5:00 AM with a massive headache, yet surprisingly she was very happy. She stretched out her sore muscles and neck, when her logical side kicked in, she was confused about 2 things...

One, why was she sleeping on the couch? It's her house after all. She tried remembering what happened yesterday, but her memories blacked out after Barry created a snowflake...

Two, why did she have a really bad headache, like as if she drank way too much, yet still felt happy and energized about something, and her body was tingling with a weird sensation that seemed to calm her for the most part... And that's until she looked down...

"AHHH!" Caitlin shrieked with a very un-ladylike shriek that would put the black canary to shame and curled up in a ball, trying to shield her body as if someone was watching her.

She was embarrassed, and more confused... She was naked from the waist-down, she was sleeping on the couch, and her furniture had some pretty big stains.

After quite a while, she looked up and couldn't help but smell a very strong scent, it smelled almost like bleach and urine mixed... Wait...mdoes that mean that I... Caitlin being a doctor, easily identified the substance, she looked down south, then she covered her eyes and started shaking her head.

"No no no" she didn't want to believe that she was the one who did that... But she was partially naked so that didn't put her mind at ease... And for the life of her she couldn't remember why. She could put the blame on Barry, but he's a male... Speaking about Barry... I hope I didn't do anything in front of him or hopefully he didn't see me... Barry was a gentleman when it came down to those things, but she couldn't help but wonder if maybe he took just a little peek at 'her goods'...

And then there's frost... wait, why isn't she talking?

"Frosty?" Nothing.

"Earth to Frost", No response.

Caitlin sighed and rested her head on the edge of her couch. No undergarments forgotten, "This is gonna be a interesting day" she was worried about her other half, Caitlin have gotten used to Frost and felt like it is going to be a lonesome day, and she needed to get up and run early to S.T.A.R Labs so she can see why Frost is not responding.. The thought of losing Frost crossed her mind, but she pushed that thought away as fast as it came. Caitlin was determined to never let that happen.

And she needed pants to make her dreams come true.

*INSERT LINEBREAK*

Barry's house

Much like what happened with Caitlin, the same thing happened to Barry... except much worst.

He felt like he had been mind controller by Grodd for a good 30 minutes, which to Barry was a lifetime and more. He tried getting out of the bed, but surprisingly enough he didn't have enough strength, so he just sighed and fell back to the same position he was in.

"What time is it?" Harry asked no one in particular, but was pretty surprised when he looked at his phone clock and noticed it was 5:00 AM! And he was a pretty heavy sleeper, so that's saying something. He might even be able to arrive earlier than Caitlin.

Caitlin... That brought a small smile to the tired speedster's face. He wondered what happened yesterday since he could remember he wanted to go to Caitlin's because he was hungry, and also wanted to escape iris's cooking, but he can't remember anything past the moment which he made the flash emblem with a snowflake ring.

After a while Barry just sighed and gave up thinking and then flipped around to look at his supposed wife, and 'chef' when said wife wasn't there apparently, and Barry started to panic since iris normally stays after Barry leaves for the day, plus it's only 5:00 AM... and the only sound he could hear in the house was his own breathing.

With renewed strength Barry started flashing around the house, he checked the kitchen first, no avail. then the living room, also empty.

He then checked the bathroom and sighed in relief, thinking that since the door was locked, then iris was in the bathroom.

He then started walking towards his bed and was proven incorrectly when he found a note under his alarm clock that he apparently missed, and the note said:

Hey Barry,

Sorry for leaving you alone, I needed to get a paper done for tomorrow since I got a big tip on a mysterious person, and it couldn't wait.

Love, Iris.

Who would send Iris a tip on a 'mysterious' person after midnight..? That didn't sound right... Iris isn't the type to go head-first into danger... Well maybe just a little bit, but still.. Leaving your husband after midnight for a "Tip" doesn't sound very convincing, and so that's when CSI Barry kicked in.

He looked back at the note and noticed the letters connected to each other looked like she was writing quickly, almost as if she was either scared or excited...

Barry then sat on the edge of the bed and started rubbing his eyes. "Why couldn't she just wait till later on today" Barry said, speaking to himself, since he was truly confused... That was until he caught the sight of a shirt poking from under his bed...

He bent down and picked it up, identified it as iris's shirt, he then tried smelling it, it could tell him wether it was the one she was wearing when she went to sleep it, or it was an old t-shirt. And what he smelled didn't put his mind at ease... Not one bit.

Did she really do that? Barry then in his anger, eyes blue and white hair, froze the shirt and threw it up in the air, and about halfway through the drop, he punched it with a lightning-filled punch, and ice shards just went everywhere, even in his knuckles and even started dropping blood, but his freezing abilities healed it almost instantly, under different circumstances he would've been asking how? Why? When? but he couldn't care any less.

He didn't like the smell of the shirt one bit, it smelled like a man's scent, and it was definitely not his... He didn't want to believe it... but everything was was against iris, he only had one thing more to do... He turned his head around and looked at iris is side of the bed, because if what he thought was correct, he was not going to be a happy speedster.

Barry started walking towards iris is side of the bed, ever so slowly, hands trembling and hoping against hope that his wife wasn't cheating on him...

He started with the blankets first, they didn't smell differently, then he slowly went to the pillows.. The first one didn't smell any differently from the other ones, that is until he flipped it around and noticed a little stain on it...

Oh how he started seeing red... But he couldn't rip it apart if he didn't get a sample and test to see to who it belongs, since it looked dried up and didn't have a very strong smell, and who better to take it to other than his favorite scientist, Caitlin Snow. she would be able to identify it easier and more accurately than he would be able to.

So in less than 20 seconds, Barry took a bath, ate and fully changed his clothes, left the bedroom in its state of absolute disaster, grabbed the pillow and ran towards S.T.A.R Labs.

*INSERT LINEBREAK*

S.T.A.R Labs

Caitlin was just about to sit on her chair when Barry came flashing in and due to his incredible speed, and Caitlin caught off-guard due to the sudden pressure, she missed the chair and stumbled backwards, but before her bum could hit the ground, two strong arms wrapped around her waist, and she couldn't help but let out an inaudible moan.

"Ohh.."

Barry didn't seem to hear what caitlin said, but nevertheless he helped her up to her feet before giving her a sheepish smile and started rubbing the back of his head.

"Sorry... I didn't think you'd be here this early, I mean it's only like what... 5:30?" Barry apologized, since Caitlin usually comes after six, Cisco comes at seven-thirty and he usually comes at ten.

"It's alright, no harm done." Caitlin waved her hand in a 'its-not-a-big-deal' manner and tucked a loose strand of hair behind her ear, an action which made her look very adorable.

Barry just gave her a lopsided grin in return.

"Now mister, the real question is why did you decide to come early today? Did you get kicked out of your own house?" Caitlin said playfully while looking at the pillow near the door frame with a raised eyebrow.

Barry in confusion mode, followed her gaze and noticed the pillow at the doorframe, that's when he remembered why he had thrown it in the first place.

"Oh That... I need your help in something" Barry said while bringing Caitlin's chair back, and grabbing his own chair and putting the pillow on it.

"Oh sure, whatever you want." Caitlin said with small smile.

Barry just nodded his thanks with another lopsided grin, he knew he could always count on Caitlin whenever he needed something, and as soon as he remembered the reason that he came this early, that smile seemed to fade as fast as it came.

Oh no... Caitlin thought, and gauging from his face reaction, it wasn't going to be something pretty. I wonder what has he gotten into this time.

Barry took a deep breath and started explaining what has happened from the moment he woke up, the missing memories, bad headache, iris leaving in the middle of the night after getting a "tip", and how did he come to the conclusion that Iris is cheating on him.

how could she... How could she cheat on the most perfect person in the world... Barry is a selfless, loving and a handsome guy at that too! Caitlin's blood was boiling, almost as if she was Killer Frost... Her knuckles were white from grabbing the edges of her armrests, almost enough to make the metal bend.

Barry seemed to notice her anger, and he wasn't planning on becoming an ice sculpture anytime soon, so he gently took a hold of her hand, almost as if it was the most precious thing on earth, and kissed her knuckles in a manner of thank-you, for caring so much about him, because he would truly be lost without Caitlin in his life.

He couldn't help but wonder if maybe Eddie was still alive, would he and Caitlin be together... this is not the time nor place to be thinking about these things...

As soon as Barry's warm lips touched Caitlin's knuckles, she seemed to snap out of her inner tumor and felt heat rising to her cheeks.

"Sorry..." Caitlin apologized for letting her emotions take over her, while looking at their joined hands and interlocking her soft fingers with Barry's strong ones.

"No, I'm the one that should be sorry, I shouldn't hav-" Barry was interrupted by Caitlin squeezing their interlocked fingers, indicating that there was nothing to be sorry for.

"You shouldn't, that's what best friends are for..." Best friends... Caitlin hoped that one day they might be more than just best friends, since if Iris was cheating on Barry, and as selfish as this might sound, caitlin has tried to be with Barry for 6 years... But then again, Iris had both Eddie and Barry wrapped around her finger. Caitlin reasoned with herself.

Barry just nodded his head again.

"Let's get investigating shall we, Mr. Allen?"

"Yes we shall, Dr. Snow."

*INSERT LINEBREAK*

"I'm calling Iris right now" Barry said while putting his phone on the table and turning the speaker on so both Caitlin and him can listen and execute the plan.

Caitlin just nodded and brought her chair closer to Barry's so she can hold Barry's hand in a comforting manner, an action that Barry was really grateful for, if his cute smile was any indication.

Now about the plan...

*FLASHBACK*

"Okay, so let's start with analyzing the pillow" Caitlin said while getting up and going towards her lab.

Barry just nodded while standing up and following Caitlin with the pillow in hand, and he couldn't help but stare at the way her hips swayed, it was mesme- No! I'm a married man! Barry's irrational side thought, then his rational side kicked in. And you're about to be a married man that got cheated on four weeks before his death. Barry couldn't help but agree with his rational side, if Iris was going to leave him, why did she have to do it when he was most vulnerable?

After their trip that was filled with comfortable silence, they finally reached the medical lab where Caitlin went to get some equipment, and Barry just sat at the bed closest to Caitlin's chair.

He was thinking about one-hundred and one thoughts, all jumbled together about Iris, and if she was truly cheating on him, would Caitlin become something more than a friend? But he didn't wanna make her think that she was just the rebound girl, nor does he want to break her heart when he dies... And maybe she didn't think of him in that way... so he just gave up on thinking before he got a massive headache.

Sometimes thinking at light speed isn't worth it.

And it was a good thing that he did, because Caitlin came back with what looked like a pair of scissors and cotton swabs.

Caitlin then placed the scissors and cotton swabs on the table and sat on the chair next to her computer. "The pillow please?"

Barry just stood up and handed her the pillow, exchanging nervous smiles and sat back on the bed, watching Caitlin working at an impressive speed, she was definitely in her element, and he decided that if he was going to die for her, it was going to be worth it.

Caitlin did sacrifice everything for Barry, and it's the least that he can do to make it up for her.

*INSERT LINEBREAK*

"And... It's done!" Caitlin said while looking at the results with Barry hovering right over her shoulder.

"So...?" Barry could see that there was no dark matter in the other guy's DNA, so he knew it couldn't be him.

Caitlin then turned sideways enough to be able to see both the results and Barry. "It looks like there's no dark-matter in his DNA, so it's definitely not you, and then there's the sperm molecules, they dont match your DNA" Caitlin said while gesturing towards a little ball with a tail attached to it. "Which means -"

"- He released on Iris" they both said at the same tome.

The only thing that was stopping him from tearing apart everything in this room, except for Caitlin of course, is Caitlin's hand touching his forearm lovingly.

"But why..." Barry was on the verge of tears.

"I'm not really sure, but there could be a possibility that it maybe was old sheets, or maybe Iris was forced, since it was almost impossible to extract anything from the stain since it was quite old." Caitlin said

With renewed hope, he looked at her eyes, and he saw sadness with a little bit of hope, which confused him greatly almost as if she wanted Iris to fail. "What you mean?"

"It means if we can get a blood sample from Iris, we could determine if she did make love with a different person, and took it willingly" what she said next pained her greatly "that is unless, you both had... You know, before?" Caitlin said, with hope in her eyes, she didn't know why, but she always refused having sex with men after Ronnie died, and even then, they didn't have sex, she in-fact never had before, and hoped that Barry never had either.

"No... We never had, at least I didn't" Caitlin sighed in relief, but it went unnoticed by Barry. "How are we going to get a blood sample from Iris?" Barry said, confusion and determination evident in his tone.

"Well, you could call Iris and ask if I can take a blood sample, if she asks why, tell her that we made a new security lock pad that requires blood signature or something along those lines so she can be keyed in by Cisco"

Barry seemed to think this over and over through his head, it wasn't a bad plan at all, Iris wasn't smart at all when it came to technology, and Cisco has made some crazy things in the past, to the point that a lock pad with blood signature sounded like a walk in the park for the crazy engineer.

"That actually doesn't sound to bad, how very Slytherin of you!" Barry said with a laugh.

"Oh shush you!" She couldn't help but laugh as well, she loved the playful Barry more than anything in the world.

And to Barry, Caitlin's laughs were a beautiful melody, his ears didn't deserve to hear such a beautiful laugh, but he couldn't help but love every second of it.

*FLASHBACK ENDED*

The phone kept ringing for another minute, before Iris finally decided to pick up.

"H-Hey Barr" Iris said out of breath, almost as if she was running a marathon.

Barry looked back at Caitlin with a nervous smile, and she squeezed his hand in reassurance.

"Hey Iris, is everything alright? You sound exhausted"

"Oh.. Um, I s-spilled some coffee on my pants, nothing much... How are you?"

Barry looked back at Caitlin and mouthed 'she's lying', Caitlin nodded in understanding. It's not a good idea to lie to a CSI.

"I'm good, how's the tip that you got going? Hopefully got a good story?"

"Yeah, very good"

"Glad that something worked out, I wanted to ask you something." Barry said while looking at Caitlin for confirmation, and she nodded a positive.

"What's up?"

"You know how Cisco gets crazy with his toys right?"

"Yeah"

"Well he upgraded S.T.A.R Labs' security system, now it's keyed by blood signature, meaning only people that Cisco keyed in can access the building"

If Barry told me that Merlin was real, I would believe him. Caitlin thought with a laugh.

"So what does that mean?"

Here goes nothing and everything. Barry thought bitterly. "Caitlin needs to take a blood sample for Cisco so he can key you in as well, can I come pick you up?" Barry said while squeezing Caitlin's hand, hoping that she would say yes.

"NO! I- uh... Sorry, I meant yes, just give me 10 minutes, I need to take a shower so I can get rid of the coffee, I'm at the office by the way."

Barry started rubbing his forehead, trying to ease the upcoming headache. "Alright, be there in 10"

"Love you"

Barry didn't even say love you back, and just closed the call, only thing keeping him steady is the grip that he had on Caitlin's hand, it was painfully hard, and he just realized it.

"Oh I'm Sorry -" Barry started apologizing before he was interrupted by Caitlin hugging him.

"It's okay.." Barry instantly wrapped his arms around Caitlin and started mumbling 'how could she' and Caitlin started rubbing circles on his back, promising that she's gonna make Iris pay for breaking Barry, her Barry...

A/N: Sheesh! I think this chapter is 4,000 words without the Arthur notes, I only had two days to prepare it but I didn't want to keep you guys waiting... Hopefully you enjoyed my new style in writing and like where I'm going... I was planning to add a big cliffhanger, like big big big big, but I just couldn't fit it in, I promise on Merlin's purple socks that next chapter is gonn be lit.

Where have I been you might be wondering, nobody leaves a perfectly good story, and then doesn't leave a notice or somethin... So, to make a long-story short, my Laptop drowned... Literally drowned. I had lost 1 finished chapter and new one that was half-way through. And I have been late as of lately because a couple of trips here and there, also built around 43 cases, so you could say I got enough dough to last me for a couple 'o months.

I just recently built a new pc for meself... Ikr selfish... Anyhoo, Since I finally settled in one place at least for the next year, if nothing goes wrong of course. I didn't really remember what was the email that I used until I tried 6 different emails, finally got it when I was about to give up. (I didn't have my data backed up... Smart thing to do... considering you're a pc geek) and yeah...

I also cringed a couple of times when I re-read my story a couple of times... I noticed I'm not giving enough time for a character to do all the thinking, nor describing actions sufficiently, so I decided as a pardon for making y'all wait, especially after my note thing received 300 views in 2 hours... I'm going to re-write my story either after I have 2 pre-made chapters, or after I'm completely done with the story...

Which means, more quality chapters for you! And more writing for me... yay...

(this Arthur note could be a chapter by itself...)
