The season 7 finale came with unexpected goodbyes and a new twist in the Fraser time-travel saga.

But it turns out, she might actuallybeone of their own.

Claire overhears Fanny singing a song from the 20th century.

In turn, that would make Fanny their granddaughter.

“The audience are going to be quite shocked as well.

The repercussions of that are definitely going to play out in season 8.

In addition to this massive reveal, the episode was jammed with other developments.

And Bree seems more keen on returning to her parents' time than the 1980s.

Rachel (Izzy Meikle-Small) and Ian (John Bell) face both great joy and sorrow.

Rachel is expecting their first child, which she hopes will be born back on the Ridge.

What lies ahead in the final season ofOutlandercan only be guessed.

Luckily, we have producer Matthew B. Roberts on hand to help us make those guesses more educated.

Where did the idea to make Jane and Fanny the daughters of a surviving Faith come from?

That is not a twist we’ve seen in the books yet.

Book 10 might explain, but honestly, I have no clue what’s in book 10.

How is having this new granddaughter going to change the course of Claire and Jamie’s lives?

Over the course of the years, when you pull a thread, the butterfly effect happens.

Bree and the kids finally reunite with Roger.

But it sounds like she’s pretty keen on returning to her parents instead of modern times.

Is that a choice they’re likely to go through with?

Well, again, being as faithful to the books as possible.

Where do you think that goes?

Just like with Murtagh.

Murtagh dies at Culloden in the books.

I’m not going to say what happens, but things happen.

It was a timing issue.

Even cutting that episode, we wanted to create that tension of “like get there in time.”

And I do think they would’ve been successful.

It feels like a big step forward.

And that’ll definitely play out in season 8.

One of the saddest moments of the show yet was poor Rollo’s death.

As you had with Murtagh and Buck, did you consider making him an immortal dog?

That’s all I’m saying.

How cut up was John Bell and the whole team that day?

It’s pretty heart-wrenching to watch.

But it was hard.

Obviously knowing that the actual dog, spoiler alert, is okay.

But those moments are always so heightened when we know we’re going to lose a character.

Someone you’ve spent day in and day out with.

So what lies in store for him?

Because he’s out in the cold a bit with William and Jamie.

Claire, at least, is more understanding.

Certainly in the last episode, which I thought was really poignant.

It’s not just swept under the rug.

We’re headed back to the Ridge.

That’s clearly where Jamie and Claire have their heart set right now.

There are going to be quite a few surprises in season 8 of who pops up.

Sanne Gault/Starz

We just learned thatOutlander: Blood of My Bloodis coming in the summer.

Does that mean that it will air before season 8?

I can’t say.

Can you give us a sweeping tease of what we can expect from season 8?

It’ll be a veryOutlanderseason.

I’ve watched it 10 times.”

Originally, you all thought you might be ending the show with season 7.

The simple answer is yes.

Because it had to.

We had to keep the series going, so it had to end in a different way.

Now we have more of a cliffhanger as opposed to some sort of conclusion.

And when we got season 8, we were well into the writing and breaking of season 7.

So, we adjusted accordingly.

We shifted some story and pulled story up and moved story around.

Now in season 8, there’s going to be some closure to the story.
