She is going. She never stopped to decide where, but she's been walking for a day and a half with a pack on her back wearing stolen pants and that's honestly good enough for her.
(It wasn't any different than any other fight, really: she did something very herself, they were furious and she screamed at them and they told her she was a disappointment and she shut herself up in the little corner of the house that was made available to her, and she suddenly realized that she could just leave. So she went.)
The trees get thicker, and the shafts of light filtering through the branches get rarer, and she lost the path she was on a long time ago, but she keeps on walking with a kind of spiteful glee at the fact that nobody could possibly tell her to stop now, and she will get killed in a dark and sinister forest if she fucking feels like it.
