"Do you think we have not tried?" Baze counters, irritated. "Are not still trying, even if we must stop now and then to take the time to keep ourselves alive?" Nothing Baze has actively done here has been frivolous, all focused on survival and, to an admittedly lesser extent given he spent a lot of time too depressed to do much and a couple weeks too sick, learning about where they are. Being told that he's apparently not trying at all is offensive. "If you think you can find something to get us out of here, you are welcome to try, as well. I would probably be happier going back to being dead."
