Only to make the situation a worse one, Mary was accused of killing her second husband in 1567. Henry Stewart’s body was found outside the home after an explosion and the speculation was that he survived that, but was murdered by another person.
The second half of Reign Season 3 will be starting sometime in spring and if the winter finale kept you on the edge of your seat, the premiere to the next half of the season will be worth tuning into. Barrowman will play the perfect villain and in the show that is exactly how the Scottish leader is perceived.
As of right now, John Barrowman is penned in as a “guest star” for the rest of the season. If things go well, fans are likely to think his role should stick around unless he is killed of, of course. As of right now, there is no confirmation that he will become a fixture on the set after this season.
