Grimm, Ep. 3.21, “The Inheritance” sets up a personal finale
In its first two seasons, Grimm fell neatly into the modern network procedural form, starting and ending a given season with heavily serialized episodes (and maybe throwing another couple in around mid-season) while keeping to standalones the rest of the time. This season, however, the show has experimented with far greater serialization, thanks to Adalind’s weekly adventures in Europe earlier in the year. For the most part, this experiment backfired, with too much time given to an underdeveloped arc.
