Snow always made Christine on edge, she didn't express it just like Bones did, more handing out warm clothes and less swearing. Nyota knew this, and it was understandable, Christine had came back to their room exhausted more than enough times due to cold inflicted illnesses. So when Nyota was part of the landing party on a world so cold they would only beam down directly into the building, and weren't permitted to leave, Christine was worried. Missions went well more often than not, but a ice planet with no escape from the negotiation building made her nervous.
So Nyota had let her pile her with a thermos of coffee, let her give her a lecture on the begining signs of hyperthermia and even went as far as wearing the trouser version of her uniform (it was that or thermal tights and the trousers fitted her well) And standing in the transport room she gave Christine a thumbs up and blew a kiss.
The negotiations went well, the talks were friendly and formal, and everything went to plan and quicker than expected. Nyota translated perfectly, watched as Jim talked, and then before they beamed up they were taken on a tour of the building. It was beautiful, smooth walls insulating them from the cold, low ceilings and tapestries filled with history. The tour ended in dome shaped room with glass for walls, thick but see through, shaped so the snow never settled on it. It was a religious place they were told, to some it was a reminder of all they were given, to some it was a reminder of all they stood to lose. A glass monument to how fragile they could be, snow whipping around outside, the landscape untouched (underground was the only safe way to travel) it was beautiful.
After asking and explaining she was allowed to take a holo of it, of the snow pelting down, the ground thick with it, whatever water frozen in strange sculptures caused by the wind. She knew it was a better memento for Christine than any of them getting sick (which was what normally happened) The hosts were happy she seemed interested in their culture, explaining the technique to make the glass, how to shape the dome properly. She translated the stories to an eager Kirk and interested Spock, watching out of the corner of her eyes as the ensigns gazed out in awe.
When she beamed back on board Christine and Bones were there, immedietly on them like worried parents. Feeling skin, checking heartrates and asking questions. When satisfied they were all well they were sent to change immedietly, and Christine followed her. In their rooms Christine was obviously still nervous (hypothermia couldn't be diagnosed instantly) and Nyota tried her best to calm her. Told her of the history, of the art, then finally of the dome, showed her the holo and watched as her girlfriend melted.
"It's beautiful Nyota!" moving closer to the holo image she marveled at the brillance of design, and how the room seemed built with safety in mind. Nyota took this chance to scoop her into a hug, laughing gently as Christine blushed. "You're beautiful!" Nyota said laughing as the blush deepened "Even when you're worried like a mother hen!"
Christine rolled her eyes and was about to remind her of the countless times she had double shifts due to ice and snow. "You care so much, it's one of the things I love about you" the words took the argument out of her, and she couldn't help but curl closer. Then she began pushing Nyota back "However!" she stated firmly as though she wasn't waddling backwards still hugging her giggling girlfriend "I don't want you getting sick!" cutting off potential arguments by tipping them onto the bed "so we should cuddle for heat! and we shouldn't get up until we need to eat"
They pulled the blankets over them, curling into each other and talking about everything. Christine asked questions of the negotiations and told her of Bones irratability whilst they were gone. And Nyota laughed along, talking about the art and what they would eat tonight, even tickling Christine to get her to agree to putting marshmallows in their hot chocolate. And then they just lay together kissing occasionally, the weight of the day making them drowsy, they could eat after a nap.
