Ok, the title is clickbait. There are comets coming but it's fine. Fi tells us all about the 1910 arrival of Halley's Comet and the ensuing panic. Claire talks about Jack the Ripper and it is pretty gruesome but she really tried to leave out the worst of it because she loves you and doesn't want to give you bad dreams. It's still pretty rough. It's also loooong so we hope you can put up with us lol.
