On her first night in the creepy dollhouse, Kara couldn't sleep. Beside her, Leoben was snoring and he was doing it wrong.
She found it ironic, as she didn't get any sleep last night as well, but the reason was lack of snoring then. Sam's breathing was too labored now to sound like a proper snore and it crept her out.
On the second night she really needed the rest so she had to ignore Leoben's snoring somehow. It used to be nice when Sam did it, hearing him gave her a proof that he was still there even when she was too sleepy to watch him. She couldn't stand it now but she couldn't close her ears. She still didn't get more than a couple of hourse of uneasy napping.
She spent her fourth night in the Cylon's bed wondering what was exactly wrong with Leoben's snoring. It sounded like a Raptor that wouldn't start, a nasty mechanical sound that made her itch. Maybe there was a feature that made the skin-jobs different from humans, besides the obvious, like resurrection and copies. Or maybe it was just her, as she couldn't actually put her finger on any real difference between human and cylon snoring. It still sounded wrong.
On the seventh night, she killed him and fell asleep in the silent room.
On the tenth night she asked Leoben to sleep on his side or whatever, just shut the frack up. He did as asked and slept quietly from that moment on. It seemed to be a relief to him, just as much as it was to her. Maybe snoring wasn't a built-in Model Two's function. She still got to rest peacefully now, so that was a win.
On the fifteenth night she couldn't sleep until she heard his quiet, even breathing.
On the thirtieth, she waited for him to fell asleep before she even attempted sleeping.
On the fiftieth, she stopped telling herself it was because he couldn't hurt her when he was in the cylon dream-land.
On the hundredth day she purposefully killed him in the morning just so that he would come back before she would need to go to bed.
On her first night back on the Galactica, Kara couldn't sleep. Beside her, Sam was snoring and he was doing it right.
