After the failed attempt to save the captives, Rey was put into captivity herself. They put her into a small cell with shadow-colored walls and no windows. Her cell was close to Kylo Ren's sleeping quarters, so he could "keep an eye on her."
Rey didn't like the sound of that, but kept her mouth shut.
She asked them how long she'd be confined. They refused to tell her.
Rey tried asking Ben instead.
He told her she could die in her cell for all he cared.
Fuck, Rey didn't care either.
