It’s difficult to imagine Jamie actually going through with killing Murtagh, but no fan can definitively rule it out.
The fifth season of Outlander is on the way, and it hopefully won’t waste any time in paying off on the big Murtagh cliffhanger.
Well, because Murtagh died a long time ago in the books.
Season 4 ended with the reveal that Jamie had been tasked by Governor Tryon in raising a militia, hunting down the Regulators, and killing their leader, who just so happens to be his beloved godfather.
