Previously on Downton Abbey: Mary was seriously depressed about Matthew dying, but bounced back enough to start taking a more active role in the running of the estate and to start playing two suitors off of each other. The new lady’s maid has a secret that Thomas knows about, but she’s got an ally in Molesley, who’s now a footman. Tom made the acquaintance of a rather pushy and grating local schoolteacher, and a lord began flirting with Isobel. Edith consummated her relationship with Michael just before he departed for Germany to try and secure a divorce and promptly disappeared after a run-in with some brownshirts. Now pregnant (because the universe can’t stop crapping on her for even a second), Edith secretly gives birth, and then stashes the kid with a local farmer who kind of owes the Crawleys a favour.
Edith bikes off to the Drew home, which appears to be a converted church, and spies on her now toddler daughter happily helping Mrs Drew with the laundry.
