When Jig suggests that "we can have everything"? she is actually implying that, in fact, they cannot have everything and that the American is ignoring the fact that they must make difficult decisions. Jig is facing the choice of having a baby or having an abortion. If she has the illegal and dangerous abortion, she cannot have the baby. If she has the baby, she cannot continue the free and irresponsible life of travelling around Europe that she is currently enjoying. Moreover, if ‘everything’ includes marriage, the American isn’t even offering that option. Thus the comment highlights the difference between everything the American wants and everything Jig wants.
