'Reign' sneak peek: Catherine and Mary meet ... the new queen?

Reign fans have seen what it looks like for Catherine and Mary to run a country—that is, what it looks like for Catherine and Mary to blackmail, to lie, to argue, and sometimes, to agree. But one thing that remains unseen is what it looks like for Catherine and Mary to live as commoners.

In an exclusive sneak peek from tonight’s episode, Mary and Catherine are forced to go undercover as commoners after their carriage is attacked. And during their time as normal folk, the end up coming across—the king and queen of France? Well, not exactly. They run into a pair of Mary and Francis impostors, but instead of speaking up, they decide to have a little fun.

Reign airs tonight at 9 p.m. on The CW.
