Jamie (Sam Heughan) and Claire (Caitriona Balfe) are officially no longer the only couple that can break our hearts on Outlander. Roger (Richard Rankin) and Brianna (Sophie Skelton) took their relationship to the next level in Sunday's episode, but just as soon as they conceded that they really wanted to be together, things went off the rails in a big way.

The two went on an adventure to a Highlander festival in the mountains of North Carolina and along the way Brianna introduced Roger as her boyfriend, which was a huge step for these two. That quickly escalated to her Brianna inviting Roger back to her cabin at the end of the first night. It could have been a wonderful, romantic night together but as soon as Roger realized they were heading towards bedroom time, he hit the accelerator and decided to propose.

Brianna, being the modern woman that she is, quickly told him to hold his horses. The rejection exploded into a gigantic fight about how the two of them viewed their relationship and where it was going. Brianna waned to be with Roger and see where things went, while Roger wanted a ring on her finger before he could sleep with her, a promise she'd be his forever. He wanted a lot of commitment that 20-year old Brianna wasn't ready to give him. Roger ended up leaving the cabin broken hearted and Brianna was stuck wondering how everything could have gone so wrong so quickly.

"[The scene] epitomizes Brianna and Roger's relationship and how they function together," Rankin explained to TV Guide. "[They] just let things build up without any real communication, and then let things explode how they will, which is pretty much what happened."

It was an eye-opening experience to find that the two potential lovers have two completely different ideas of what they want in a relationship at this point in their lives.

"I think it's a very interesting scene....You have a very modern woman for her time and, from Brianna's point of view, this very old-fashioned gentleman," Skelton added. "It's really interesting to see how they collide in this moment. We know that Roger and Bri are not very good at communicating. Here, they lay all their cards on the table and they are on very different pages about where their relationship is at and where it is going."

The friction between these two is what makes their developing relationship so exciting though, and so wildly different from that of Brianna's parents.

"With Jamie and Claire, you know they're always going to overcome it together," Skelton continued. "But with Roger and Bri, you don't. That's one thing from that scene is sort of a cliffhanger."

The two may have left North Carolina further apart than they've ever been, but rest assured this is not the last we've heard of their love story. Rankin confessed that even though Roger was spurned, there's still a spark between him and Brianna that he can't stay away from.

"It's one of those, 'Oh my God you make me so angry but I love you' kind of things. Ultimately he's going to want to come back to that," the actor said. "Even though I think they both have very valid points and they are justified reasons for why they do things, they can sometimes be at opposite ends of the spectrum...They're not on the same page, sometimes not even in the same book so it can end in a pretty heated exchange. It's by no means the last time that happens for Roger and Brianna."

"You haven't seen anything yet," Skelton promised.
