Mary's Baby Problem Chatter On 'Reign'

Considering that there's a little love triangle with Mary, Francis and Conde right now, does this mean that Francis and Mary's marriage is going to end soon as the two move on to other people? It might happen since Francis notices that Conde has feelings for his wife

Other than that, what exactly is Mary de Guise going to tell her daughter about the throne?

Odds are likely that a lot of crazy storylines are going to happen in the royal drama since the show's been renewed for more episodes in a third season. And according to TV By The Numbers, there's a good chance that the show might even get a fourth season depending on how many episodes the third season gets. If there are a full 22 episodes, then that boosts chances of another year.

Reign airs on Thursdays at 9 p.m. ET on The CW.
