Every breath she took left a mark in the cool night sky. Seemingly every move, every breathe, every thought was somehow changed under the bright iridescence of the moon. There's something about the romantic nature of the moonlight that changes the way you are. The soft snow underneath her feet made her comfortable in her own element, and the light snowflakes falling down reminded her that she was a dangerous package wrapped up in pretty paper. She was not to be trusted.

The house in front of her was an off shade of white, however the moon cast a low shade of blue over it. From afar it looked so cold to her, but it was her home. Her home that she built, with all her terrible memories locked inside. Standing on the sidewalk she could see Julian rush down the stairs in his boxer briefs and momentarily disappear before reappearing in the lounge room. His gaze searched furiously around the room and through to the dining room, as he grabbed his iPhone out from his back pocket. She knew who he was calling: STAR Labs and any associated member. She was very familiar with how this situation played out each and every time she disappeared. Only this time it was different; he put down the phone when he spotted the folded white note on the wooden coffee table; and Caitlin had no intention of being found ever again.

As Julian read the long heartfelt note, she watched on with pained emotions from across the street, not letting her face change from its stony structured expression. He fell back onto the couch as his legs gave way beneath him, not that he even noticed. But Caitlin did. From across the street she saw it all, and she knew it was right, no matter how wrong it felt to be breaking his heart. Her heart.

She couldn't let Julian keep trying to save her. Every time he picked her up from the ground and placed her in bed, she knew it was chipping away at him. The alcohol consumption was becoming a problem, she couldn't even remember the last time she'd been this sober. The last time she'd gone to work she was picked up off the ground once again by Julian, only it wasn't her in control before she'd passed out. It was Killer Frost; and Killer Frost had some bad habits.

Caitlin maybe picked up a few of those too. She'd finally realised that she couldn't be in control all the time, but it was better for neither of them to be in control than to let Killer Frost win. Alcohol provided that escape for her, allowing both Killer Frost and her to swim around unconsciously in her brain, neither being able to dominate the other.

She was addicted to a losing fight. There wasn't a cure for her, Killer Frost came out whenever Killer Frost pleased, and it was becoming so tiresome to fight it. There for, drinking each and every day really made no difference to Caitlin's being. In her drunken state she could dream about a day where she was happy again, whilst watching Killer Frost envision a world where she was in control.

When was the last time she was happy? She couldn't recall. Maybe it was when she was wrapped up in Julian's arms, or the day they first stepped into their newly bought house, or when her and Cisco would laugh at movie night, or when she successfully saved Barry's life, once again, back in STAR Labs. She missed her normal life, she missed being just Caitlin.

'Hey blubber head, if you're going to get this emotional maybe I should take over.'

'Just leave me alone."

'Whether you like it or not, I am you. Now I've fought damn hard to come back, I'm not silencing myself.'

'I know you don't love Julian. But I do. Just let me have this minute.'

'You've never let me have a single second. I was kind enough to not kill your sad sack of a boyfriend when you asked, and that's all you're getting from me.'

Caitlin turned away from her home, deciding against fighting her. It was just too damn exhausting to try anymore.

'Good. Now walk away. He'll... he'll be fine.'

'Did you actually just try and comfort me?'

'I'm just trying to get the hell out of here, I can't stand you looking at that house anymore.'

'You were there when I bought it.'

'So?'

'That's your house too. Its your home.'

'Cut the crap, princess. That awful shade of mauve you painted the bedroom with alone makes me want to take over and burn the house down. Or freeze it and shatter it into a million pieces. Your pick.'

'Do you want to get rid of me too while your at it?'

'The hell are you talking about Princess? Of course I do. Unfortunately you're me and I'm you. I can't really kill you without killing myself.'

'Yes you can.'

'... Seriously Princess, the hell are you talking about?'

'I'm talking about taking over, permanently.'

'...You'd never let me'

'I'm sick of fighting you. I'm sick of the drunken falls and the bruises every morning. I'm sick of disappointing Julian and breaking his heart. I'm sick of watching through my own eyes when someone else is in control of me.'

'That's the problem. You'll always be there. Just like I have to watch you stare at Julian all the time. You know surgery isn't an easy thing to watch either, might I add? Or when you're going down on Juli-'

'Okay. I get it.'

'I get that its painful. Trust me, I have the exact same feelings about this as you do. Except I don't give a shit about the things you do, just like you don't give a shit about my thoughts. Last time I checked, you took the cure and it didn't work. So, we have to learn to coexist or I'm taking over fully. Because I sure as hell am not letting you take the reigns again. Nor am I hearing any more of this crap about you allowing me to be the only one in this body. You can't kill yourself without killing me.'

'I'm going to mum's office and she'll sort it out. We're separating ourselves once and for all. I can't live with this pain anymore.'

'You're bluffing. You're just going to go take the cure again so that I'll be killed!'

'I'm taking the cure so that I can be killed!'

'Please. Caitlin Snow doesn't give up. You know I might not have a degree in biomedicine or whatever, but I'm not dumb enough to fall for this bullshit.'

Caitlin shook on the sidewalk as Killer Frost gave one final push and took over her body.

'I'm in control. So stop lying before I walk back down the street and freeze him to death.'

'I'm telling the truth. I only have one request though.'

'Of course, there's always a technicality. What is it? You want to sleep with him one last time? You want to see the Eiffel tower at night? You want your favourite meal once last time? What? What is it?'

'I just want you to promise me something.'

'...I'm listening.'

'Please, don't come back here. Don't hurt him. Don't hurt my friends. And don't take off that ring on your finger. I just want one last reminder on my body of who I used to be.'

'Why the ring? Why not go get a tattoo that I won't be able to remove?'

'Because... he's the last thing in my life that's... good, and quite frankly, he hasn't just been helping me these past few months. He's been helping you too.'

Caitlin felt Killer Frost calm, allowing her to take control again.

'Alright Princess. I won't come back here. One thing I will say about him is he does have excellent taste in jewellery.'

'How do I know I can trust you?'

'I've kept my word about not hurting him when I've been in control previously, haven't I?'

'I was still there though.'

'True. Listen... I maybe care about the little Brit too. It'd be a shame to leave our child without a father.'

'...We haven't taken that pregnancy test yet...'

'You and I both know what its going to say. Don't worry, I've thought about this and I fully intend to give the baby to Julian. I'll have the ring and he'll have the baby.'

'...This is wrong, isn't it?'

'You giving up on your kid? Yeah, totally wrong. But, hey, I didn't propose this situation. You did.'

'You seem oddly calm about this.'

'I may be in your body but it's not really mine, is it?'

'It's still your DNA though. That kid might even inherit these powers. Doesn't that make him/her every much yours as they are mine?'

'If you're trying to talk yourself out of doing this, I have no problem with that. I've kind of gotten used to having you around too you know.'

'I can't raise a baby if I'm you half the time though.'

'What are you saying? I'd be a terrible mother?'

'You know that's exactly what I'm saying.'

'I don't know what you want me to tell you Princess?'

'You mentioned coexisting before, yes?'

'I did. Getting drunk every day and night isn't really my cup of tea Cait.'

'It's not exactly mine either, you haven't given me much of a choice though.'

'Well I'm giving you a choice now sweetheart.'

'What exactly are you proposing then. I imagine your idea of coexisting is much different to mine.'

'Probably. I've been seeing you working on that little plan of yours to duplicate our body and separate our minds. How about you put all of your strength, time and energy into that and for the mean time, I'll be quiet... well, quieter then I usually am.'

'I told you to stop spying on me at work.'

'When do I ever listen?'

'Good point. Okay, fine. In exchange I'll give you an hour a day to do... whatever it is you want to do. No killing though!'

'Well now, what's the point in that? I'll stay locked up, thankyou very much.'

'Alright, I'm just going to keep that idea on the table though, just in case you change your mind later.'

'Whatever Princess.'

'Why are you being so... easy right now?'

'Lets just say I'm not exactly that thrilled with the idea of you going permanently.'

'So what I'm hearing is... you want to be roommates when we are in different bodies?' Caitlin joked.

'Well I'm not paying rent.'

'Of course you aren't.' Caitlin scoffed.

'I'd just like free reign to do whatever I please without your voice nagging me all the time or trying to drown me in vodka. But also I'd enjoy being able to see the little baby have a family.'

'You've gone soft, Frost.'

'Shut up... only for my own offspring though.'

'Whatever you say Frost.'

A/N

Whaddup piiiiiiiimppppsss. Hope y'all are having an excellent Saturday so far (or whatever day you are on). I'm taking requests for one-shots and/or plot ideas if you desire that from me, I'm currently writing a sick-fic which will likely be the next update (for my girl Write-to-You), also check out my profile for my updating schedule if you haven't already.

Follow this bad boy for weekly updates, I think I might extend this one-shot into more of a 3 chapter story... eventually. I'm drowning in work and uni but heeeeeeeyyyyyyyyy snowbert just keeps popping into my head. I just HAVE to write.

And to the lovely guest that reviewed last chapter, thank you so much! I would have liked more of an explanation with why Killer Frost was so evil but hey, there's always season 4 (and fanfics) to explain it.

Till next time guys! Hit me up with those requests!
