The interplay between theoretical advances and observational discovery has been truly dynamic in WET science. In this brief paper I highlight a few examples of this interplay from the point of view of a ``linear theorist'': the PG 1159 stars and the pulsating DBs. The data provided by the WET gives theorists cause for celebration and reflection; the failings in particular provide useful future directions for theorists in light of the observational challenges.
