She has become invested in their perfection and has even come up with names for them. Rachel calls them Jess and Jason. As she watches them she is reminded of the divorce she went through two years earlier with her husband Tom. She is still hung up on him ever since he divorced her because of her problems with alcohol. Rachel is an alcoholic who has recently lost her job. She doesn't have a home and she lives with her friend Cathy who is under the false truth that she is still employed. One day on the train Rachel sees something that shatters her perfect image of this couple that she's been observing.
