Outlander: The Next Generation
There is a line that Jamie says to Claire in Season 3 after they reunite.
He is talking to Claire about Brianna, and he says, "because of her we will live forever".
Jamie, I felt always thought of his children and his grandchildren as blessings. He talks about them often in that regard. "My Greatest Blessings".
I think that we will see an Outlander sequel and it will be Outlander: The Next Generation and it will follow the Grandchildren of Claire and Jamie. The main heroine will most likely be Fanny.
The Big Easter Egg comes in the finale. Claire comes in to talk with Fanny before she leaves with Jamie at the Battle of King's Mountain. Fanny is sitting there at the desk and on the desk right in front of Fanny is what appears to be Claire's Diary. They also make it a point to show that Fanny is a lurker and she hears things. We have Fanny spending a lot of time with Bree's children. We have the rock breaking in Fanny's hands and hearing the buzzing exactly like Jem did. We have Mandy being able to see the color auras. We have Fanny seeing the books from the future. Mandy apparently can hear animals. Jem can see things in dreams.
I don't know if we will get a Movie to wrap up Jamie and Claire. What I do think we will get is a wrap up of their story inside the telling of the next generation's story.
I think Jamie and Claire both died at King's Mountain. I do think that Claire's powers brought them both back. I think the reason we see that their bodies are laying on a standing stone that is broken is because the energy that it took to bring them back to life also allowed Jamie to travel with Claire. I don't think Jamie and Claire are in the same time any more as when they died. I think they came back to life in a different time. Roger comes back to the Ridge and tells Brianna that when he and Ian went back to finally persuade Claire to come home with Jamie's body, he discovered Claire is gone and so is Jamie's body and they are nowhere to be found. He also figures out that they were laying on what looked like was a standing stone that had been broken in half. Brianna and Roger speculate as to what has happened. Sharing details about Time Travel and their experiences. Fanny overhears it all. She rushes to find Claire's diary and reads it. She then confronts Mandy and Jem and makes them spill even more.
Fanny armed with all this information and knowing she too is a time travel sets out to find her grandparents and even perhaps to try and change the fate of her own family in the process.
