It’s an in-joke for anyone who has watched the television adaptation of Outlander, and it is one of the main reasons I have gone off the show.
Despite the book series being – at its core – about Claire and Jamie in the past, the show’s producer is obsessed with the actor playing Frank. I find Frank deathly boring, and just because someone thinks an actor is good doesn’t mean the fundamental elements of the book need to be changed so drastically.
So a fan made a joke Frank-themed poster for the first of April!
I have no idea who to credit for making this!
