So what does this mean for the ongoing series? Well, the narrative has to be more than Claire's predictions, for better or worse, coming to pass in reality, otherwise we wouldn't have much of a story.
One way of dealing with this is to have characters unknown to history, but well-known and even beloved to us in the story, lose their lives in a winning battle. This is what happened to good and sad effect last night. Of course, Jamie and Claire are the best-known anonymous-to-history characters in Outlander, and their fates are therefore always up in the air.
At least, to some extent. We've already seen this season that Claire not only survives these battles, but makes her way back to the future - and this is, presumably, because Jamie didn't. But there's no way that Jamie can die in this story (and, again, I haven't read the novels), so this pitches us into the biggest question of this season:
What happened to Jamie to make Claire leave him, short of his dying? Was Claire lying to Frank in some of what she told him? Not only that - but with Claire in America, at least for a few years, how on Earth or in fantasy will she ever get back to Jamie? Will there be some strange stones in the vicinity of Cambridge, MA?
None of that seems too plausible to me, which is one reason I'm looking forward to further episodes.
