A new episode called "Necropolis Now" finds John (Aaron Ashmore) squaring off in an intense confrontation with someone from his past. Meanwhile, Dutch (Hannah John-Kamen) is stuck in her own personal hell — specifically, a space elevator — with several insufferably pompous Qreshi, who inexplicably start dropping dead around her, one by one. Luke Macfarlane also stars.
