Each year, "Outlander" co-executive producer Maril Davis teases lines from the show's script. Recently, the producer shared parts of Claire’s (Caitriona Balfe) dialogue heard on set.

“A pleasure, Mistress Fraser” is the first dialogue that Davis posted online (see below). The other is “The pleasure was mine,” which is obviously what Claire said in response to the first line.

Davis is currently in Scotland to oversee the production, but the producer revealed that the lines were from the day before when she had visited the set. Davis did not visit the set that day as she spent her time in the office.

After the tease, fans started to guess who said the first line. It is quite obvious who said the second. Given that the dialogue is pretty vague, it’s difficult to take a guess. Some fans think it is Young Ian’s (John Bell) line, while others think this is something that the new character Stephen Bonnet would say.

Jamie (Sam Heughan) and Claire will spend a lot of time in America in season 4. The story will move to the colonies this year, away from Scotland. The Frasers will meet new characters here, including fierce-looking natives.

Leaked pictures from the production set have already teased some of the newcomers. The producers are yet to release a full list of new cast members.

The plot of “Outlander” season 4 may have the same format as season 3. There will be Jamie and Claire’s life in the past, then there will also be the budding love story of Brianna (Sophie Skelton) and Roger (Richard Rankin) in the future. The plot this time around is based on Diana Gabaldon’s book “Drums of Autumn.”
