Lydia becomes part of New York’s high society through her marriage to Mr. Tillotson
She leaves her husband in order to lead a life together with Mr. Gannett outside the bounds of social conventions
Because of her background she is less willing to accept the social restraints and is more capable to discern the deficiencies of those values
She refuses to get married again and feels pressured and misunderstood by Mr. Gannett
At the hotel she has to realize how much she loves being among other people and that she needs the contact with other people because she cannot live without it permanently
She enjoys being together with all the people who are exactly like the people she ran away from
Lydia has difficulties to put all her principles into action. Indeed Lydia attempts to escape from the situation which shows her courage and determination but her coming back signifies her failure
Her escape fails because of the existing social conventions and morals which she cannot shed as easily as she thought
In the end she does not leave Mr. Gannett because she loves him and she needs him to persist in society
She strives for an independent life but has to realize that the individual, especially a woman without a man, is nonviable
Lydia is the most intelligent and analytical character in the plot, which is shown e.g. by the way she explains her situation to Gannett or how she forecasts her future predicament
