how does jane show her inner resolve in chapter 4

Mrs. Reed tells Mr. Brocklehurst that she hopes that Jane’s time at Lowood will reform her, particularly her tendency to lie, an accusation that stings Jane. After Mr. Brocklehurst leaves, Jane defends her honesty to her aunt and launches a series of recriminations. Mrs. Reed seems stunned and leaves the room, but Jane's victorious feelings soon give way to remorse. She feels better later when Bessie confides in her that she prefers Jane to the other children.
