Even though fans have access to the "Outlander" books written by Diana Gabaldon, season 2 of the TV adaptation will still be surprising and different. Executive Producer Ron Moore explained to ThreeIfBySpace during the 2015 San Diego Comic-Con that even book fanatics shouldn't expect to know everything that season 2 has to offer. 

"Fans are looking forward to certain things, and you want to satisfy that, and at the same time you want to surprise them, you want to catch them off guard, you want to scare them, like 'Oh my God, Frank's going up the hill! If he goes through time, I'm quitting watching the show!" he said. 

Moore continued to explain that the second novel, "Dragonfly in Amber," is a far more complex piece to adapt due to its numerous characters and time jumps. The novel opens in the 1960s and switches between flashbacks and the novel's current time period before actively heading to the past, but Moore hinted that season 2 will open quite differently. 

In his statement, Moore confirmed that there will be some changes and differences in the television series that fans can compare to the books. Season 1 was fairly faithful to the source novel but as more complex storylines weave into book 2, the show needs to make changes to maintain consistency and to fit the necessary pieces into the TV series' time restrictions. 

This is the same challenge that other producers and directors meet when adapting novels and comic books to television or movies. Films in particular need to cut out a lot of content from their source materials since most movies need to be able to tell their stories in just two hours. 

The second season primarily takes place in Paris after Claire (Caitriona Balfe) and Jaime (Sam Heughan) narrowly escape death in Scotland. There they will attempt to end the Jacobite uprisings and alter history while dealing with Claire's pregnancy. 

"Outlander" season 2 has no official premiere date as of the time of writing.
