Ed or JImmy? Is there even a difference?

        In I Am The Messenger  by Markus Zusak, the main character named Ed does something that catches my attention as I read the novel. In the book Ed repeatedly sees an elderly lady that is constantly alone in everything that she does. So, Ed gets the idea to comfort her, while first meeting this women he learns her name is Milla, and that she thinks he is her deceased husband name Jimmy. without giving time to think Ed plays along with the idea to being Jimmy. In the book we see many times where Milla talks to Ed about the past she says, "' You were always so handsome ,' she tells me. She even touches Jimmy's face on the photos..." (Zusak,56).  This quote illustrates one time that we see Milla talk to Ed as if he is Jimmy, which in her eyes he always is. The thing that bothers me a little about Ed playing along to being Jimmy is that I feel bad for the women. I think, What if she realizes one day that Ed isn't Jimmy and becomes heartbroken? What if something happens to Ed and he stops visiting her, then Milla would be even more confused than she already is. I don't know what I would do if I was in Jimmy's situation but for some reason I feel as if it is not right for Ed to lead Milla onto thinking he is Jimmy. lthough ontop of that, part of me feels it is very helpful that Ed pretends to be Jimmy because it brings Milla so much joy that I would hate to see be taken away from her. Also lastly I believe that it may be good for not only Milla but Ed to keep the old women company because it proves to himself that he is doing something with his life and that he can make people happy. In conclusion, I do not know what I would do if I were put into Eds Postion maybe I would comfort Milla and lie like Ed did about being Jimmy. But also maybe I would still comfort Milla but be truthful of who I am. I understand that Ed is trying to do the best he can do to keep Milla happy, I am just unsure if he is taking the right steps to doing that or if there is a different way to her happiness.
