With all of the near-death experiences the Fraser family has faced in Outlander, it's easy to forget the elephant-sized house fire in the room that is supposed to take place sometime in the 1770s. In Season 4, Bree and Roger found a newspaper clipping that said a house fire kills Jamie and Claire, causing her to travel back in time and warn them of the future threat. And with the next Outlander season teed up to tackle the sixth book, Jamie and Claire may want to start fireproofing the Big House soon. Spoilers ahead for Outlander Book 6, A Breath of Snow and Ashes.

The mystery still remains, however, on what (or who) the spark will be that starts the fire on the show, though the stage has been set for one particular Outlander character: Richard Brown. In this theory about Richard Brown starting the Fraser's Ridge fire, revenge is best served pipping hot, even if it does diverge from Diana Gabaldon's books.
