We examine light curves obtained for several low-mass subluminous [WC] central stars. Recent visual and photoelectric measurements made of the [WC10] central star CPD-56°8032 indicate that it has undergone a second decline event resembling those seen in the R Coronae Borealis (RCB) variables. Other [WC] central stars examined (He2-113, SwSt1, and He2-99) do not show declines. Various evolutionary scenarios have been proposed that link the [WC] stars, RCB stars, and other types of hydrogen-deficient objects. From an observational point of view, the evidence appears to be circumstantial.
