Television actress Alanna Masterson is set to join season four of AMC’s monster hit zombie drama “The Walking Dead,” premiering Oct. 13. The news comes on the heels of Christian Serratos’ casting as survivor Rosita Espinosa.

According to Deadline, Masterson will be introduced mid-season as a zombie apocalypse survivor. She will recur throughout season four with an option to return as a regular in season five.

Masterson doesn’t have many notable projects under her belt, but she has guest starred on a few television series, including “Terminator: The Sarah Connor Chronicles,” “Malcolm in the Middle,” “Greek” and “Grey’s Anatomy.”
