Foreshadowing in the Outlander chapter
I don’t think the chapter really foreshadows all that much. Really, it’s about keeping Bree in the moment to witness history. There is a moment with Cinnamon realizing that he knows very little about William and his relationship with Brianna. This could lead to something, but I can’t see why it should unless Cinnamon isn’t everything he claims to be.
Adapting the Go Tell the Bees That I Am Gone chapter
I don’t really see this chapter being used in the TV series. There isn’t really that much need for it. There’s not going to be much time to tell all the stories in Go Tell the Bees That I Am Gone, and I suspect everything with John Cinnamon and Lord John Grey will be skipped over. This could mean avoiding Cinnamon in the story at all.
I would like to see the show make use of Bree’s talents as an artist, but again, it comes down to time. The show offers a look at that through subtle moments such as Claire seeing the artwork Bree left behind before going through the stones to save Mandy. We know she’s talented, and the show could opt to avoid this to help keep the focus on some of the more important storylines in the series.
