The introduction of Bertha Rochester in Jane Eyre by Charlotte Brontë had an immense impact on her current life and aligned with the disappointments of her past . Bertha Rochester is the crazy woman who lives in Mr. Rochester's attic. She lives there because she is Mr. Rochester's wife which has not been revealed to Jane. Mr. Rochester married her, not knowing what he was getting into. Bertha Rochester is also the sister of Mr. Mason who was bitten and stabbed by her. Her existence and secret marriage to Mr. Rochester gave Jane the dissatisfaction of not being able to be Mr. Rochester's wife and caused her to leave Thornfield and find a new home. The relationship between Berth and Mr. Rochester caused harm to Bertha. Locking him in the attic was not the best solution for their marriage. Bertha occasionally escaped and when she did, she immediately set off after Mr. Rochester. One night, as Jane was about to go to bed, she heard demonic laughter. He thought it was Grace Poole but it was Bertha. At the time Jane didn't know it and when she left her room to see what it was, smoke was coming from Mr. Rochester's room. Bertha lit the curtains and Mr. Rochester's bed in chapter 15, page 151. Bronte writes: "Some creaked: it was a half-open door, and that door was from there." I no longer thought of Mrs. Fairfax; I no longer thought of Grace Poole or of laughter; in an instant I was in the room. Tongues of flame sprang up around the bed: the curtains were on fire. Amid the fire and steam, Mr. Rochester lay motionless in a deep sleep. Jane tried to wake him up, but he was just lying there, so she threw a bucket of water on him. Bertha tried to take away the only man she loved and cared about. The crazy lady also had an impact on his life... middle of paper... I can't stand such words now. That I am not the wife of Edward Rochester is the least part of my misfortune, I asserted; that I have awakened from the most glorious dreams and found them all empty and vain, it is a horror that I could bear and master; but that I must leave him definitively, instantly, entirely, is intolerable. I can't do it. After Jane left, she was able to free herself from the disappointments of today and the past. Disappointments included being orphaned, broken and alone, losing her best friend and not having a family. Her response was to simply leave the discontents behind. The introduction and existence of Bertha Rochester in this novel had a profound impact on Jane's life. It caused Jane to leave the love of her life and relive her discontent at not being wanted by the Reeds. Bertha made Jane experience what happened in the past again in a new place..
