Show: Supernatural
As a recurring guest star in the second and fifth season on the series, Alona Tal took on the role of Jo Harvelle, the girl series creator Eric Kripke described as “an innocent girl who wanted to be a hunter.” During her stint on the series, the Israeli actress matures from an impulsive girl-next-door to a tough and willingly self-sacrificial expert hunter, a role the show’s fans were excited for her to reprise in the current, seventh season.
