Have you been watching Outlander? It’s Starz’s genre-mashup show about a 1940s British woman transported back in time to 18th-century Scotland (how timely!), where she maneuvers various intrigues, of the medical, political, and romantic variety. It’s an oddball mix of tropes and themes, but likable in all its offbeatness. Based on a cherished, rapaciously read book series that began in 1991, Outlander has a vocal corps of intensely devoted fans. And yet, it’s entirely likely that you, dear reader, are not one of them. Which is why I’m writing to you today, urging you to change your mind. Because Saturday night’s episode, “The Wedding”—which centers on the two romantic leads doin’ it for the first time—is when the show really kicks into high, sexy gear.

Watching the first six episodes, it can be a little confusing as to why the books have such a fervent fanbase. Sure there are some interesting culture-clash plotlines, and yes the handsome Scot, Jamie (the hero from hunk heaven, Sam Heughan), does smolder well with our lead. But, well, the show’s temperature plateaus at a cheery bubble, never reaching the furious boil we expected from the marketing materials. But, aha, during “The Wedding,” that all changes. Like, seriously changes.

I knew there had to be a reason why fans of the books are so particularly hot and bothered by them, and were already so devoted to Heughan before the show had even aired. It's because they knew what was, er, coming. The sex that happens during tomorrow night’s episode isn’t so tremendously graphic that it rivals any of the senseless f--king on Game of Thrones. But it’s more intense and personal, and in that way daring, startling even. That’s probably owed to the delicately tortured romantic connection between Jamie and his new bride, Claire. See, Claire has a husband whom she loves and hopes to return to in the 1940s, but she has to marry Jamie in the 1700s to protect herself from an evil British army officer. Of course, there was always a romantic connection between Claire and Jamie, despite her loyalty to her modern-day husband, so when she finally relents to those urges on their wedding night (they have to consummate, lest the marriage be deemed invalid), it’s done with a heady mix of guilt and abandon. It’s quite a potent combination, the florid, fleshy result of hours of careful build up. Other shows could take lessons from Outlander in how to expertly delay gratification.

Hopefully they didn’t delay it too long, though. While there was some sexy stuff in episode one, the subsequent five were all pretty chaste, focusing on clan politics and personal growth. Thoughtful, melancholy, and sharply acted, those episodes were all fine television, but were they enough to keep people invested? Maybe not. If you gave up on the show or avoided it altogether, I’d suggest you play some catch up and tune in with the rest of us panting sickos and voyeurs tomorrow night. Because it is some seriously steamy TV. And don’t you want to see what all the fuss is about?

And what a fuss there is! Yesterday, while watching the big episode, I tweeted something offhand about it and have not stopped getting frenzied responses since. Outlander fans are legion and have ears and eyes everywhere, scanning the farthest reaches of the Internet for any mention of the show, especially for any hints about this particular episode. They are very excited about this episode. Many of them really have been waiting 20 years to see this coupling happen, which may seem a little strange to some of us, but is at the very least a rather stirring testament to the power of fandom. And, with an interesting tweak of the usual wedding-night scene—instead of the wide-eyed woman being ravished by her lusty new husband, on Outlander the man is the bashful virgin, while Claire is the experienced lover—there’s some interesting gender politics to pay attention to, as well. They might not freely admit it, but chances are that some moony-eyed bookworm in your life is already sweaty about the storied sexfest that’s about to go down. (In all ways.) So why not join in on the only-slightly-dirty fun? Who knows, maybe you’ll fall in love with the show too. Its seductive powers ought to prove especially strong tomorrow night.
