The DAV white dwarfs have, until recently, kept their interior secrets hidden despite the asteroseismological probes thrown at them. Recent work has shown that the hotter DAVs are a remarkably homogeneous class whose properties can be discovered through temporal spectroscopy. It is not immediately obvious, however, how the cooler DAVs fit this new scheme. G29--38, in particular, is a mysterious object with its reported infrared excess, possible radial velocity variation, and bizarre pulsation properties. Combining 7 seasons of photometric data with other published observations, we report new discoveries and attempt to provide a unified model for the system.
