Mary Mourns Francis In New Extended Promo For 'Reign' - Watch Here!

We’re STILL not over last night’s episode of Reign! We mean, did you hear Francis’ (Toby Regbo) last words to Mary (Adelaide Kane)? Gut-wrenching!

And by the looks of the new episode next week, we’re going to need a lot of chocolate to get through it…and tissues.

The official description of “Fight or Flight”: Mary realizes she must help Catherine (Megan Follows) in her quest to become regent, even at the risk of hurting the alliance with Scotland. Meanwhile, Claude (Rose Williams) is determined to help Leith (Jonathan Keltz) marry while Elizabeth (Rachel Skarsten) struggles with the prospect of losing Dudley (Charlie Carrick).
