Final answer:
Mrs. Olston's impression of Lanner changes from viewing him as a dangerous man known for violence to recognizing his gentleness and kindness, especially in his interactions with Mrs. Larkin and Fay.
Step-by-step explanation:
Throughout the passage, Mrs. Olston's impression of Lanner undergoes a transformation. Initially, Lanner is seen as a man with a reputation tainted by violence, a 'hater and a killer of Mormons' whose very name inspires a blend of fear and fascination in Jane Withersteen. However, as the narrative unfolds, Lanner's true nature is revealed through his gentle dealings, especially around Mrs. Larkin and the child Fay. Mrs. Larkin's praise of Lassiter as a 'good man' who 'loves children' and his evident care for Jane and Mrs. Larkin during her illness softens Jane's perception of him. Lanner's departure in sadness and preoccupation elicits sympathy from Jane, but when he shows a tender, almost fatherly affection towards Fay and Mrs. Larkin, Jane's understanding of him deepens significantly. What emerges is a complex figure, one capable of great gentleness and love, standing in stark contrast to his ominous reputation and alleged misdeeds.
