Well, it looks like Jenny (Katheryn Winnick) and viewers of ABC's Big Sky will be seeing a lot more of J. Anthony Pena's Deputy Mo Poppernak during the upcoming third season, with Pena officially promoted from recurring to series regular. In addition, the Winnick, Kylie Bunbury & (now) Jensen Ackles-starring series is also welcoming Luke Mitchell (Blindspot), Seth Gabel (Salem), Henry Ian Cusick (Lost), Anirudh Pisharody (9-1-1), and Madalyn Horcher (Gracepoint) to the cast in recurring roles. In May, viewers learned that Jamie-Lynn Sigler has been promoted to a series regular and that Reba McEntire had joined as a series regular. First reported exclusively by Deadline Hollywood, the third season finds private detective Cassie Dewell (Bunbury), undersheriff Jenny Hoyt, and newly appointed sheriff Beau Arlen (Ackles) maintaining order in Helena, Montana. But when a local backcountry trip led by charismatic outfitter Sunny Barnes (fka Sunny Brick) (McEntire) goes awry, the trio faces their most formidable mystery yet when the series returns on September 21st.
