Mrs Birling is more shocked at Eric's actions than those that lead to the death of Eva
Eric
"she was pretty and a goodsport"
"I was in the state when a chap easily turns nasty"
Sheila
"it frightens me the way you talk"
Reversesyntax puts focus on her being frightened, creating a bigger question - what is she really frightened of, the way her parents talk or the consequences of the bourgeoisie's ignorance?
Mr Birling
"Look, Inspector, I'd give thousands - yes, thousands -"
Gerald
"Everything's all right now, Sheila"
The Inspector's final speech
"There are millions and millions and millions of JohnSmiths and EvaSmiths"
"all intertwined with our lives"
"they will learn it in fire and blood and anguish"
Mr Birling, when he realises the Inspector is not real
"By Jingo! A fake!"
Simple exclamation of surprise, but also links to jingoism
The last line
"[As they stare guiltily and dumbfounded, the curtainfalls]"
