Voice lets her go.

Shell doesn't know how long it's been. She doesn't know where she is. She doesn't know how to get home, or if she has one.

She stands on Voice's doorstep. She blinks slowly at the brightness.

She walks in a random direction.

Downsiders aren't big on charity. It's not like it's going to kill her if she doesn't get help. It's not like she's unfamiliar with the effects of dehydration and hunger; Voice didn't always remember to take good care of the pet in the basement. Shell walks, and when she's tired she lies down on the ground and sleeps, and when she wakes up she walks, and every few days she curls up on the ground, waits to torch from thirst, and then gets up and goes on.

She doesn't count the number of times this happens. It doesn't matter.

She walks. She has nightmares. She walks.

On an unremarkable day on an unremarkable street after unremarkable stretches of years, she feels herself cross a telltale threshold of dizziness and headache: she cannot make significant forward progress towards Not Where She Is Currently Located until she torches or (less likely) someone gives her a lot of water. It's possible she'll be able to sleep through this torch. She sits. She leans on a wall. She should probably pick up the next sharp object she finds. Maybe a piece of broken glass will present itself. Then she can skip these parts.

She sits, and she closes her eyes, and she waits. If the buildings around her would ever have seemed familiar, they don't now.
