We're back in Antoinette's head now. Antoinette doesn't remember how or why she ended up in the room – she's just really, really cold.
She thinks that if she only saw "him" (in this section as in all the others, Rochester is never named), she could persuade him to let her go, but she hasn't seen him since she's been locked up in the room.
She's aware that a woman named Mrs. Poole sleeps in her room. She watches Mrs. Poole count the money from a money bag tied around her neck, then get drunk and fall asleep.
She tries whatever Mrs. Poole is drinking – it's clear and tastes nothing like rum, but she feels that she can think and remember more clearly after she's had a taste.
