- Jerome 'Jerry' Marvin: My wallet... I've been robbed!
- Professor Susan Drake: Don't you dare call us thieves.
- Jerome 'Jerry' Marvin: I didn't call you thieves.
- Professor Susan Drake: You looked at us and shouted "I've been robbed". Willy nilly, you called us thieves.
- Jerome 'Jerry' Marvin: I didn't.
- Professor Susan Drake: We're willing to pay your fare to Havana and back to Cristobal.
- Jerome 'Jerry' Marvin: Look, sister; I've paid my own way ever since I was six. Before that I sponged a little on my father and mother - and I've never quite forgiven myself. The thought of it sometimes drives me to drink.
- Professor Drake: Right this very night, I'm so proud of you. I'd like to wake Tom up and give him a good thrashing for not being another girl like you.
- Professor Susan Drake: This is just as big a job as smashing a few atoms. After all, we only pass through this life once and any little kindness we can leave along the way should be left along the way.
