Previously on Downton Abbey: Bertie’s cousin dies, and suddenly he’s a Marquess. This is great news for Edith, or at least it is until Mary drops the bombshell about her sister’s illegitimate daughter. Bertie’s shocked that Edith didn’t trust him with the truth and breaks things off with her. Everyone’s furious with Mary (and deservedly so) and she gets a lot of lectures from everyone in her family, before realizing that her shoddy behavior is because she’s upset about breaking up with her boyfriend. Thanks to a final pep talk from Violet, Mary finally admits that she wants to marry Henry and, after a quick detour by Matthew’s grave, the two arrange the world’s fastest wedding ceremony. Elsewhere, Molesley discovers that he’s actually a pretty great teacher when he just acts like himself, and Thomas’ depression over not being able to find a new job reaches such a low point that he tries to kill himself.
(If you need a more in-depth refresher, last week's recap is right this way.)
