What is Blanche's reaction when she sees the doctor who has come for her? scene eleven

A doctor and a matron appear, in exaggerated institutional garb. Blanche goes to the door, expecting Shep Huntleigh, and is fearful when it isn't him. She backs into the apartment. Mitch won't look at her. The matron follows her in, and approaches sinisterly. The staging becomes less realistic as lurid shadows play on the walls and voices echo against the Varsouviana. Blanche tries to run away but the matron catches her. Stella tries to stop them but Eunice holds her back. Mitch and Stanley fight, and Mitch collapses in sobs.

The matron pinions Blanche's arms and asks the doctor if she should just a straitjacket. The doctor says only if necessary, and then removes his hat, humanizing him. The doctor addresses Blanche directly and politely, and tells the matron to unhand her. Now calmed, Blanche allows the doctor to help her up and lead her outside. Holding on tight, she says "Whoever you are – I have always depended on the kindness of strangers."
