Outlander's Cesar Domboy and Lauren Lyle Talk About That kiss 

Warning: This post contains spoilers for Outlander season 3, episode 10, "Heaven and Earth."

fans have only just met Marsali on screen. Played by Lauren Lyle, she\'s already shown she\'s Laoghaire\'s daughter, both in her passionate love for Fergus and disrespect for Claire. But you\'ve got to admire her gutsy determination. Not only did she steal away on a ship to be with her beloved, but she\'ll stop at nothing to make sure they secure Jamie\'s blessing to get married—and her ingenuity gets him freed from his cell.

As for Fergus, he\'s torn between the woman he loves and the only father figure he has ever known. In Sunday\'s episode of

, we saw him struggle with Jamie\'s request to help him escape. Ordinarily, the former pickpocket would do anything Jamie asked. But now he has Marsali to consider, too, and he knows that if an escape attempt goes awry, it might prove fatal for all three of them.

That\'s just when the two get caught up in a rather steamy moment. Following a passionate kiss, Marsali wants to go further, but Fergus eventually puts it all on ice. There\'s probably much more where that came from; we spoke to Lyle and Domboy on set about their almost-climactic love scene and why their romance is more modern than your average 18th-century pairing.

Considering the time period, Fergus and Marsali are being very modern.

Lyle: All of it, the way we’ve developed the relationship, our chemistry with each other, the way that we kiss—it’s very modern. The fact that we’ve totally gone against 18th century norms, everything you should do, as a woman especially. What I should be doing is what my father says, and go and have a little life and be a housewife. And I just completely ignore that and go against that. And you do, too.

Lyle: And they’re such romantics. I think the danger of period drama is, if you want it to be real, if you want it to have real chemistry, you have to act on instinct. We don’t want to over-rehearse how we kiss. We just try things, and do things, and experiment with what feels really good, and what makes both of us feel attracted to the other in that moment.

Domboy: The kiss is the moment where you have to give up on being true to the period, because this is not the French court, so we don’t have to have perfect veneers about everything. This is the moment where the audience just wants to be, “They’re in love.” And I don’t even know how it was during that period…

Lyle: Was kissing even documented back then? It would make no sense for us to have the relationship we do, to have gone against all the rules of what we should be doing as young people, to then not touch each other. They’re young, and in love. I think that’s the main thing we bring to the show this season. We inject the moments of love and happiness and fun, a fresh new energy. And [Fergus] is like [Marsali]\'s first boyfriend! [
