There are several things that are interesting with Sam Heughan’s comments, which were made during a recent FB Live session.
This squares with Voyager, the third book in the series, which catches up with Jamie post-Culloden before Claire eventually returns to her lover’s time.
However, according to Heughan’s comments, we won’t be getting that reunion right away.
Outlander has shifted things around from the books before, but the note about “episodes before” indicates we won’t be seeing a reunion in the very first episode.
