Nelly's Passionate Feelings

While narrating the story, Nelly often is biased when she's telling the past to Lockwood. She often criticizes Catherine, and calls her many names; although, she is everything she says she is, I think Nelly is jealous of Catherine's beauty and power. Nelly is almost the same age as Catherine, and has been working as a servant for a long time. She, additionally, might also have some positive feelings towards Edgar, that's why she praises him a lot. I feel like Nelly might not be telling the true story all because she feels deceived in this drama.
