Mary and Marie at the wedding. Did Mary marry? Who did she choose? Watch "Consummation" to find out.

Amy Brenneman will appear on Reign as Marie de Guise, Mary Queen of Scots' mother.

Mary shows up looking all blue... little did she know the many love and adventures that awaited her. This gown is young and fresh, while blood red velvet cape leaves no doubt who is stepping out of the carriage.

The King is not in his right mind. Will he be of any use to anyone in "Liege Lord"?

Is 15-year-old Mary a queen or Francis' prom date? Sometimes it's difficult to tell.
