Nicely plotted, allowing an expansion of Tempe's story. When a skull is identified as her mother, it leads to a huge can of worms, including the reappearance of her brother, Russ. Brennan has been carrying anger inside her for the longest time and blames her brother for abandoning her after her parents disappearance. Much of the charm of this is watching Brennan deteriorate while she goes through the processes of putting aside her fury and getting down to business. We find out that her parents were involved in some shady dealings and were not the simple, reserved creatures she imagined them. I thought this was the best of the first season.
