Further updates of character concept:
-not only was she left for dead, she believes that she IS dead
-there may be some Cotard's syndrome-esque issues going on here
-but in fairness, she got run over by a car and then dug herself out of a shallow grave, so you can kind of see why she thinks that
-the part where she keeps obsessively checking herself over to see if she's started rotting yet is a little unsettling, though
-the wealthy family she was a maid for prior to her accident had uhhhhh Issues even by the standards of rich dysfunctional shitheads
-very fancy, very old blood old money vibes, very thinly-veiled hints that there's something Very Wrong Here beneath the surface, but the domestic staff are too busy trying to survive the entirely bland and mundane horror of living in crushing poverty to actually do anything about it and/or figure out the details
-basically she was a nameless, voiceless background character in a gothic horror novel just waiting to happen
-except now she's come back from the grave, kicked down the door, and announced that mom said it's HER turn to be the dramatically tormented Byronic heroine
-she's gonna pose on storm-wracked cliffsides and defy the will of God, fuck you
-prone to occasional vicious headaches for no clear reason, or at least no reason that she seems inclined to discuss
-you'd think that might be something to do with getting run over by a car, but they were happening before then, too...
