Step-by-step explanation:
The student who befriends Jane at Lowood in Charlotte Brontë's novel, Jane Eyre, is Helen Burns. Helen becomes a close friend to Jane, providing her with companionship, guidance, and intellectual stimulation. Despite Helen's eventual death from consumption, which deeply affects Jane, her friendship leaves a lasting impact on Jane's life and development as a character. Fay's presence in Jane's home leads to Jane spending more time with Lassiter, a rider who had been riding for her but had not sought her out outside of business matters. Lassiter is immediately captured by Fay's charm and becomes more involved in Jane's life as a result.
