Helen was a symbol of acceptance a way for Jane to connect with someone who experienced the same things as she did whenever she was at her original home. Miss Temple was a symbol of acceptance as well and a little more important because she was an adult who believed in Jane's academic ability disregarding some of the things that others liked to point out about Jane. Her time at Lowood is important to the development of her character specifically because of these two people who helped show her understanding.
Helen helped Jane become an adult. When Jane came to Lowood, she was always upset, and never thought rationally. When she talked to Helen, she learned how to act as a young woman. Miss Temple is a mother figure to Jane. Jane never had a mother of her own, so Miss Temple took Jane under her wing and helped her develop. I hope this helps!
