Act 1 - The Sheltered Daughter

At first glance, Sheila seems like your typical privileged 1940s girl. Priestley deliberately describes her as just "pretty" and "pleased with life" - notice how he focuses on her looks rather than her brains or achievements? This reflects how society viewed women back then.

Her initial reaction to Eva Smith's death is telling. Sheila's main concern isn't the tragedy itself, but how it's ruined her happy evening. This selfishness shows just how sheltered and narrow-minded her upbringing has made her. She's never had to think about people outside her wealthy bubble.

However, there are hints that Sheila's different from her family. When she declares "these girls aren't cheap labour, they're people," she's already showing empathy that her parents lack. More importantly, when she learns about getting Eva sacked, she doesn't make excuses - she owns up with "it was my own fault."

Key Point: Sheila's willingness to accept responsibility marks the beginning of her transformation from spoilt girl to socially conscious woman.

Acts 2 & 3 - The Moral Awakening

By Act 2, Sheila's become the sharpest person in the room. She sees right through her mother's attempts to distance herself from "that sort of girl." Her brilliant line "You mustn't try to build up a kind of wall between us and that girl" directly challenges the class system that keeps the wealthy comfortable.

The real power shift happens in Act 3. Suddenly, Sheila's the mature one whilst her parents act like children. She calls them out for "being childish - trying not to face the facts" - talk about role reversal! The girl who was being treated like a kid is now the adult in the room.

Her sarcastic comment that "we're all nice people now" cuts straight through her parents' hypocrisy. They think they can forget their actions just because the Inspector might not be real. Sheila knows better - the moral questions remain the same.

When she echoes the Inspector's warning about "fire and blood and anguish," we see she's truly absorbed his message. Priestley uses Sheila to represent hope - proof that the younger generation can learn, change, and build a more equal society.

Key Point: Sheila's transformation from selfish girl to moral leader shows Priestley's belief that young people are society's best hope for change.
