*Warning: This episode contains spoilers for Season Six of *Downton Abbey.

It's a pattern we've seen since *Downton Abbey *began: when Mary is unhappy, it's often Edith who pays the price. But this time, Mary crosses a line -- and sets up a sibling showdown six seasons in the making.

Michelle Dockery returns to the podcast to reflect on Lady Mary's comeuppance...and redemption, from her jaw-dropping fight with Edith to her heart-to-heart with Violet, and finally her wedding to Henry Talbot.

We'll also go behind-the-scenes of all the drama with the episode's director, David Evans, who reveals what it was like to film the episode's most memorable moments.

Finally, we'll dig into the rest of this week's jam-packed episode with our weekly Downton roundtable.
