Reign aired its mid-season finale in January on CW, but when will the series return to CW with the second half of season three?

A return date for the series has not yet been set. The CW Reign Facebook shared a preview for the series’ return, and it does say the series will return this spring. That is all it says though.

Mary will face a new foe when the series returns though. Entertainment Weekly reported recently that John Barrowman will appear on the penultimate episode this season as Francis’ killer.

The news outlet reported that, “Barrowman, who’s no stranger to playing bad guys, is set to play Munro, a dangerous and charismatic Scottish clan leader who harbors a sinister grudge against the Queen of Scots. So naturally, when Mary returns to Scotland, she finds herself in the presence of the man who cost her the love of her life.”
