AVClub: Reign really, really loves to put Catherine in trouble. Partially, it’s because Megan Follows can bring Catherine from arch to desperately sympathetic on a dime, which is exactly what you want when your monarch’s in peril. Partially, this is because she’s the easiest vector for the show to examine consequences. (For all the the import of their decisions, Mary and Francis just hadn’t done enough yet for things to haunt them.) In “Safe Passage,” a bunch of things from Catherine’s past—some deserved, some still bearing the factory sheen of a newly-concocted threat—land on her all at once. And it’s Mary who gets to save her.
