Brianna and Roger visit Fiona at Rev. Wakefield’s old manse only to find out that Fiona received a delivery for Jemmy which has been in a bank vault for 200 years. Inside they find letters from Jamie and Claire and what appears to be a musket ball.
The first letter Brianna and Roger read is about the fire at the Big House. Roger comes to the conclusion that Brianna is the reason for the fire. She went back in time and made matches which is what Donner used to accidentally ignite the ether. They believe they changed history and that the fire that killed Jamie and Claire can not happen because the house is already gone.
