"Outlander" stars Sam Heughan and Caitriona Balfe are overwhelmed with the reaction of the audience to their hit Starz series. The on-screen couple recently spoke at length about the future of the series and what audience could expect from the upcoming episodes.

The duo said that they are particularly pleased with the audience reaction to the "Wedding" episode. They apparently saw a lot of tweets and positive feedback from the fans and were happy to know that their hard work paid off.

"It felt really great," Balfe told Access Hollywood, adding, "There's been such nice stuff written about how that episode was and I think we all really worked hard to make it as real [as possible] and give it the space that these two people -- their love could really develop and that it wasn't instantaneous sex."

The series is based on novels by Diana Gabaldon. It is known for the steamy scenes shared by the protagonists apart from the befitting plot.

Balfe said in her interview that the way the sex scenes were filmed really struck a cord with audience. Heughan, who plays Jamie Fraser, also suggested that he and Balfe saw the wedding night scene together.

"Is it weird to say that we watched it together? ... With a bottle of wine, [a] couple of bottles of wine, actually," said Heughan, adding, "Yeah, we were like, 'Yeah we gotta watch this."

"Outlander" is currently on a mid-season break, but there is major buzz regarding the plot line of second half of the season. Throwing light on the impending episodes, Balfe assured that the second part is going to be stronger in terms of the storyline and that things are going to get gritty and dark now that her character Claire is at the mercy of Black Jack Randall.

Moreover, Claire would be torn between her two lives and it remains to be see which life she would choose.

"Outlander" season 1 second half premiere date is 4 April, 2015. Ronald D Moore has developed the series and it stars Balfe, Heughan, Tobias Menzies, Graham McTavish, Stephen Walters and others.
