I am one of those people who have seen all of Downton Abbey’s third season, including the much-ballyhooed Christmas special. Can I even use the phrase “Downton Abbey Christmas special” without putting in a spoiler alert? Now, before you throw yourself out of your chair or throw your phone out the window, you can relax. You’re safe here. You don’t need a spoiler alert for this, or for future columns from me throughout this season; in fact, you won’t even need to read them with your hand half-covering the lower part of your screen. Let me just assure you that you will enjoy the season. If you find out, or think you found out, what happens during it or in its final episode, you probably don’t know as much as you think you do. This is a clever, well-written season with plenty of surprises for you. I mean, also, #firstworldproblems, you know?
