Gerald - oldest youngest man
he provides false hope - people think that he will turn out like the other young Birlings
he wants to marry Sheila for business reasons
he is a mini Arthur - agrees with him all the time ' I agree' (A1) and 'Hear, hear! I think my father would agree to that' - he just wants to fit into society - he wants to marry and have a successful business
doesn't learn anything - he doesn't feel guilty about what he did to Eva - tries to re-engage Sheila - 'Everything is alright now' - doesn't take in how this might have effected her
