Summary
Analysis
The girl from Cabin 10 comes back with food, one pill, and a book for Lo to read. In the mirror, she catches sight of blood on her face, left from Lo’s attack, and goes to wash it off. When she comes back, Lo sees that she’s wiped her penciled eyebrows off in the process, “leaving a smooth, skull-like forehead that was instantly, unbearably recognizable.” The woman is Anne Bullmer.
The girl makes good on her promise in bringing things back for Lo, showing she’s not completely hostile to her. The sudden, unexpected revelation of her (apparent) identity is shocking.
