Maybe she's doing this because some obscure part of her brain has finally realized that she's going to die soon, and therefore there's no meaning in saving money. Just go splurge now that you're (barely) alive.
Yeah, they're always around (Becky and Eric) to pay for bills that could be auto paid.
The whole renting discussion makes me wonder: don't landlords control the houses they rent, from time to time?
Because their landlord would be probably pissed as hell, as they painted the basement, left glow-in-the-dark prints all over the stairs, hung up dozen of flags and prints, and are currently leaving finished bottles of alcohol in the kitchen alongside other litter spread all over the house, as well as dog turds in the yard. Not to mention that none of them looks clean in any way, and the two women-beasts probably smell of death and rotting flesh.
Cleaning up that house, when they'll leave, will be a nightmare.
More so if Amber dies in there.
