The Glass Menagerie scene 6 - dramatic irony

Scene six of The Glass Menagerie begins the second part of the play when the gentleman caller arrives. Oh the illusions continue! Amanda makes Laura wear "gay deceivers" because her chest is flat. Amanda just wants to create this illusion of Laura. Dramatic irony is created when Laura learns the gentleman caller's name. Tom had said before the scene started that he went to high school with Jim, and Laura asks Amanda whether Tom went to school with Jim. This is dramatic irony because the reader knows that this is the same Jim, but Amanda and Laura are unsure. Being the reclusive girl that Laura is, she refuses to go to dinner in fear of her world of illusion clashing with the realistic world. Jim immediately brings a realistic feel to the play. Jim dreams of becoming an executive and studying radio engineering. Jim wants to be successful like most everybody else. However, Tom dreams of leaving his family like their father did saying, "I'm like my father. The bastard son of a bastard!" Pardon my french, well actually Williams' french. I'm pretty sure no one dreams of becoming the bastard son of a bastard, so I think its fair to say Tom's dream is unrealistic.
