Caitlin Snow was now used to closing her eyes and opening them to find herself staring at her alter ego, Killer Frost. Initially it had been nightmares about the version of Killer Frost she had met on Earth 2, but after a little love and understanding not only had her alter ego become an important member of Team Flash, but a true friend, now they had found a way to talk to each other.
Only this time instead of finding herself in Star Labs, or her home, or even in her bed, which her real form was in now, Caitlin found herself imagining herself and Killer Frost sitting at a familiar table. Which made her blush, as it was not the first time she thought something like this, and she was worried her alter ego had discover those thoughts, and was about to laugh at her.
"This, this is..." Caitlin stammered.
"Ronnie's favourite restaurant." Killer Frost said softly, taking Caitlin's hand, "It's Valentine's Day Caity, and I know you haven't had a lot of luck with men recently, so I was thinking maybe I could be your Valentine."
"Oh." Caitlin said both in relief, and disappointment, then quickly covering by grabbing the champagne glass in front of her and holding it up for a toast, "Oh, absolutely. That, that would be fun. We should do that. So, to our Galentine's Day."
"I didn't say anything about Galentine's Day, did I?" Killer Frost pointed out in a tone which always sounded flirtatious, before snapping her fingers.
Just like that night with Ronnie a man appeared as if out of nowhere with a basket of roses and offered, "Flower for the pretty lady?"
"Absolutely." Killer Frost beamed, echoing Ronnie's words and then actions as she bought a rose and offered it to Caitlin.
"Thanks." Caitlin blushed slightly, echoing her own actions by taking the rose and smelling it, and likely thanks to her own vivid memories it was just as good, "This is..."
"Just like that night?" Killer Frost offered, "Yeah, that's kind of the point. I mean, I did think about dreaming of something different, but I couldn't come up with anything better than this. It was your favourite night, and I wanted to reclaim it for you, as while you remember it fondly, it always makes you sad."
"Wow..." Caitlin murmured, "That's sweet. Kind of weird, but sweet."
"That's what I was going for." Killer Frost admitted, then taking Caitlin's hand in hers again, "Come on, I don't know how long we have, and I'm not done showing you what a great date I can be."
Those words caused Caitlin to frown and open her mouth to ask what are other half meant by them, but all of a sudden they weren't sitting down in that restaurant any more. No, they were both on their feet, dancing in that club Ronnie had taken her to afterwards. Specifically the moment when the music had slowed, and he had taken her in his strong arms and held her while they slow danced. It had been like something out of a fairy-tale, and now Caitlin was having that with Killer Frost.
Which was kind of weird, and funny, but Caitlin wasn't laughing, or grossed out. She was touched, and she also felt something else she wasn't sure she wanted to focus on right now. Not that she could really focus on anything right now except eyes like hers staring back at her as the two of them danced.
So consumed was Caitlin in the way that Killer Frost was looking at her, both before and during the dancing, that it took a long time to notice the fact that her mirror-image wasn't in her usual get-up. She was still blue, but this was a much lighter and friendlier tone, and more to the point she wasn't just in jeans, a leather jacket and a dangerous looking pair of high heels.
Well, she learned later that her heels were still high, but she was wearing a long flowing dress, similar to the type that Caitlin had worn that night, except in her preferred colour. That, this type of dancing, and honestly everything about the situation suggested this wasn't just a friendly celebration of Galentine's Day, or worse a mockery of it. This was something else.
"What..." Caitlin finally began in a croaky voice, "What did you mean exactly, when you said you wanted to be my Valentine?"
"You're the smart one..." Killer Frost pointed out, "You tell me."
There was another pause, and then Caitlin softly pointed out, "We're the same person."
