What evidence is there to show that Mitch is still a product of his environment? Scene 3

One of Stanley's friends. Mitch is as tough and "unrefined" as Stanley. He is an imposing physical specimen, massively built and powerful, but he is also a deeply sensitive and compassionate man. His mother is dying, and this impending loss affects him profoundly. He is attracted to Blanche from the start, and Blanche hopes that he will ask her to marry him. Indeed, Mitch is a fundamentally decent man and seeks only to settle down. But when the truth about Blanche's history comes to light, he feels swindled by her.
