Unwilling to give up her love to stanley, whist also wanting to protect and care for Blanche she exists in a liminal space between them
First scene seems to fall into previous sister dynamic like back at belle reve ('MissStella!')
She laughs at her antisemitic joke
HOWEVER - blanche clothes and white collar
Shows from beginning of play Blanche is opposed to Stanley,developing into stella being forced to pick between them damagin the sisterly relationship Blanche expected them to fall back into
Paragraph Two
Attempts to remain in liminality as choosing one means ruining relationship with other
BUT - scene 4 makes definitive choice of defending Stanley against Blanche after making direct comments towards him
In turn - pushes away Blanche, indirectly? looking at blanche whilst hugging him, direct,
Scene 5 this direct push away from blanche is ostensibly fixed, Stela gone back to liminality. call backs to belle reve - but undercurrent of damage with way Blanche feels she has to defend herself fro Stanleys accusations
Foreshadows ultimate decision of Stella, same music etc
Paragraph Three
Despite Stella's illusion of choice, she could've never chose Blanche over Stanley
Shown from how whenever defending Blanche and moving towards their relationship instead of liminality - she is reminded of how she is tethered to Stanley
Scene 3 - violent outburst of stanley after she shouts at him for throwing radio Blanche switched on
Goes into labout when repeatedly questioning him why he hurt her
Whilst ay be a shock to mordern audience with the contextual factors in her choice - no means of income - single mother - heavy victim blaming of rape - its unsurprising
Conclusion
Sisters relationship is permanently altered by partiarcal norms of the time influencing Stella to choose the safety of Stanley over the risk of believing her sister and defending her.
But, she still attmepts to protect Blanche in the end 'i will go with you' ' 'what have i done with my sister', her last line in the play shouting after blanche
