I believe this describes rosemary because she can not have close relationships. it is like her relationship with Rex. some days their relationship is good and other days they are terrible. rosemary has periods where she is depressed a lot. rose Mary acted like that when she was in welch
"Periods of intense depressed mood, irritability or anxiety lasting a few hours to a few days.''
This describes Rex Walls. whenever he owed someone money and people were after him they moved. He never paid any bills and was always evading those who collected. Rex Walls never trusts anything related with the government, and is always running from them. When Jeannette got burned and was in the hosptial . Rex came to the hospital because he didnt trust them, and took Jeannette out , even though they were treating her very well, and she was having a good time. Walls also is running from tax collectors, he is a very Rebellious person.
