Outlander season six has been filled with some great storylines but it seems the end of episode five is set to throw us another one.
When Claire and Jamie are set to leave Wilmington after meeting Flora MacDonald (Shauna MacDonald), Aunt Jocasta and Lord John Grey, she hears someone whistling a tune that she knows from the future.
The tune is of course the Colonel Bogey March, and was initially written by members of the British army in 1914, meaning whoever is whistling it is also from the future.
