2. How does Rochester’s treatment of Jane change after their conversation at the beginning of Chapter 15?

He becomes more confident to her. Rochester fulfills his promise to Jane to tell her about his and Adèle’s pasts. At night she  hears what sound like fingers brushing against the walls, and an eerie laugh soon emanates from the hallway. She hears a door opening and hurries out of her room to see smoke coming from Rochester’s door. Jane dashes into his room and finds his bed curtains ablaze. She douses the bed with water, saving Rochester’s life.He says to her”You have saved my life:  I have a pleasure in owing you so immense a debt.  I cannot say more.  Nothing else that has being would have
been tolerable to me in the character of creditor for such an obligation:  but you:  it is different;–I feel your benefits no
burden, Jane.” He paused; gazed at me:  words almost visible trembled on his lips,- -but his voice was checked. “Good-night again, sir.  There is no debt, benefit, burden, obligation, in the case.”
