Shelly has pulled out one of Susan's drawings from the family's time in Santa Cruz.
At this time, Susan and Oliver are living on the water, and it's absolutely beautiful.
Oliver has received a job offer, but it's located in the middle of nowhere in Bolivia. Susan shoots down this idea quickly.
Oliver and Susan don't see each other very much these days—Oliver goes to San Francisco to look for work for weeks at a time.
Oliver is also experimenting in an attempt to create "hydraulic cement" (3.2.51). Susan pushes him to work harder on this so they can get rich and buy a McMansion in Santa Cruz.
