If only in my dreams
The Tallus let them know they were getting a Christmas present - it was that time in the world of KISS, so they were allowed to stay over for a concert, and to at least have some stability over the holiday.

Sarah almost would have preferred to miss it, stay on task, not have to think about the holidays or herself. They'd had to adapt a lot on Battleworld. Lack of trees meant using one of the local substitutes, but there were some growing crystals that looked amazing when lights were strung around them, reflecting off, and sometimes through the facets.
They hadn't had much sometimes, though the machines could produce most of what was needed. Mom and Dad both loved Christmas though. For Mom it was all about her closest approximations to baked goods and southern cooking, with a giant dinner and breakfast. There was learning carols in German from Uncle Kurt. They could go to one of the nearby regions for snowball fights and sledding.

But her favorite tradition of all was the one that was just her and her father. No matter how old she got, he insisted Santa Claus was real, and said he'd even met him once. Battleworld was far away from anything, but her father still insisted they sit on the roof of the base and keep a lookout, just in case.

Some of the others, it sounded like, were going to go for dinner and drinks and celebrate the holiday and a well deserved vacation. She assured them she'd be fine, but wasn't feeling very festive and just needed to rest before she finds the highest spot she can to settle in and stare at the sky.
