Fortunately, in spite of all we are led to believe from Jane's interview with Brocklehurst, Miss Maria Temple is of an entirely different disposition and character, as Jane herself discovers as she arrives in Lowood. Note how Maria Temple is kind and generous, ordering an extra lunch to make up for the inedible breakfast the girls were served. Secondly, she does not give credence to Brocklehurst's opinon of Jane's bad character, and listens to Jane's words rather than ignoring her. Thirdly, she is entirely different in appearance. Note how Jane describes her:
Let the reader add, to complete the picture, refined features; a complexion, if pale, clear; and a stately air and carriage, and he will have, at least, as clearly as words can give it, a correct idea of the exterior of Miss Temple...
This gives a very different impression from how Jane describes Brocklehurst earlier on in the novel in Chapter Four, when he is viewed as "a black pillar" and "a carved mask." These two descriptions hint at the hypocrisy and true nature of Brocklehurst's character that become evident as the interview progresses. Thankfully, Miss Temple does not share her employer's penchant for hypocrisy and abuse.
