The “Outlander” Season 4 premiere is almost here, but first, viewers might want to prepare themselves for what’s to come. Here’s what to expect in the 2018 episodes of the Starz drama:

Jamie’s Family Extends To America — Conveniently, Jamie has an aunt in the states. Jocasta (Maria Doyle Kennedy) will extend a helping hand when Jamie needs it, but Claire (Caitriona Balfe) won’t be thrilled that she owns a plantation and slaves.

It Didn’t Film On Location — While the “Outlander” cast and crew were lucky enough to head to South Africa to film the Caribbean scenes in Season 3, they didn’t get to leave Scotland in Season 4. Though the new episodes are largely set in the U.S., the filming happened in Scotland. That also means that audiences won’t see the characters sweating through the southern heat.

Animals Play A Part — Expect to see several animals come into Jamie and Claire’s lives. First and foremost, there’s Rollo, the adorable dog that Young Ian (John Bell) wins while gambling. Then, there’s a rather mischievous pig and a certain donkey that readers of Diana Gabaldon’s books will be excited to see.

More Roger and Bree — Though Brianna (Sophie Skelton) and Roger (Rick Rankin) have been supporting characters in the past, they really step into the spotlight this year. Audiences will catch up with Bree while she is studying at MIT and balancing a long distance relationship with Roger.

Indigenous Canadians Are Playing Native Americans — As previously reported, “Outlander” is a non-union show, so they couldn’t use actors in the American acting union, Screen Actors Guild. However, they still wanted to make sure they didn’t cast white actors to play the characters. They brought in over 100 indigenous Canadians to play the roles.

Changes To The Novels — Heughan warned readers that they don’t know everything that’s coming. “We do stick to the books as much as we can, but I think what’s great about this season is that we do — There’s some surprises in there for fans of the books, which I think is great because you guys know the books,” Heughan told the Build Studios audience. “But there’s some things in there that also are part of Diana Gabaldon’s world but you weren’t expecting.”

“Outlander” Season 4 premieres Sunday at 8 p.m. EDT on Starz.
