It has taken more than two seasons for "Downton Abbey" to do this to me. Yes, we've had break-ups and weddings and betrayals and deaths (yes, deaths) before now. We've had fights and veiled insults a-plenty. But I can honestly say this was the first episode of the show to truly punch me in the gut. If you let it, this one could break your heart.
And yes, stop reading right now if you haven't watched the episode. This is one you need to watch, I think.
