In Thursday’s new episode – airing at 9/8c on The CW – Mary finds herself conflicted. Will she return to Scotland to help out her mother, or will she be more like the Mary of last week, who was ready to be a Queen on her own to Scotland?

And while Mary weighs her decision, Francis is worried about this newcomer, wondering why he so desperately wants her back in Scotland. After nearly losing his own place in the line of succession, Francis is worried about his new wife’s safety and whether James can be trusted.
