Creativity is an interesting lens seeing as it has to do with the role imagination plays. The play is a memory play that often avoids realism. A clear moment of that is the description of the set where the reader understands the meaning the description tries to portray but with the abstract language trying to build that set accurately would be near impossible. Also, creativity comes into play in the scenes where the narrator is not present and since the play is semi-autobiographical Williams likely would not have seen either, but these conversations are still written despite not being based in fact.
In a play that has a main character so similar to the author questions about how much the two share the same perspective are bound to arise. How many of Tom’s views and desires are actually those of Tennessee Williams? Also, when thinking about this, one must consider the fact that the narrator version of tom speaks with heinsight that Williams would also have creating interesting issues as memory is fallable so perspectives could become biased over time, for example with how Amanda irritated Tom in the moment but here is a feeling of fondness for her from the narrator and a little regret for leaving a feeling that probably grew over the years.
