***The following interview contains major spoilers for the season finale***

In tonight’s episode of The Hunting Party, Bex (Melissa Roxburgh), Hassani (Patrick Sabongui), and Shane (Josh McKenzie) track down Jenna Wells (Eliza Coupe), who was known as the Killer Chemist, because she chose her victims while working at a pharmacy, killing them by replacing their prescriptions. At the end of the episode, although they do catch her, it’s not before she poisons Odell (Nick Wechsler), leaving his fate uncertain. In another twist, Colonel Lazarus (Kari Matchett) is revealed to not only have a barcode on her foot, meaning she was potentially one of those experimented on at the Pit, but also to be Shane’s biological mother whose identity he had been searching for throughout the season.

Last week, Roxburgh spoke with SciFi Vision about the finale, including filming the shootout scene, whether Bex can trust Lazarus, what she’d like to see about her character’s backstory, if she’d be open for Bex to have a relationship with Shane, what she would like to see resolved, the possibility of a second season, and much more.
