The hatch doors close with a finality that reminds Leia of her whole world tearing apart. A bright and blinding flash of light before everything she's grown up to know and love ceases to exist in one moment. Her belly swoops, exactly like before and her legs don't feel fit to keep up their steady support much longer.
Threepio's quoting facts at her and Leia wants to bite back that she knows the facts. She's a child of Alderaan goddammit, and while not quite as cold and definitely inhospitable as Hoth is, it certainly had its fair share of dangers. She knows that hypothermia can occur when a body temperature drops below 35°C, that on average Alderaan lost hundreds of its people a year.
She knows the symptoms like the back of her hand: feeling tired, confused, slow breathing, a slow heart beat and weakness. She knows that sometimes a victim can appear dead even when found, their body no longer able to keep up, just lying there motionless.
She knows that Luke is a child of the desert. A boy that had spent those first few days back on the falcon constantly shivering, the chill of space settling into his bones and setting his teeth to rattle. The natural tan of his skin beginning to fade the longer he's away from the twin suns of Tatooine. That he's built up a lean definition of muscle, but that he still isn't big by Leia's standard, or anyone's standard really.
She knows, without a doubt or any of her statistics, that Luke is in trouble. She can feel it, deep within her, settling into her bones like the cold that rips through the hangar any time the hatch doors are laid open. She should have reacted quicker. She should have known that something was wrong.
She doesn't want to leave the hangar, can't imagine leaving that space unwatched until both Luke and Han are back and grinning at her, telling her that all that worry was for absolutely nothing.
She can feel her breath start to quicken, feel her fingers start to shake. Closing her eyes and taking one deep breath in, then slowly out, trying to control her emotions, trying to shut down what she's feeling inside.
They'll be okay, she tells herself.
The three of them have survived much worse than this.
