While finishing a hunt, Sam and Dean save the life of a cheery but altogether mysterious young man. The Winchesters never could have predicted the chain of events set off afterwards. I mean, did *you* know that knights could time-travel? Neither did they! **Note!** This fanfiction draws on things already established as my own headcanon, but have not been explained anywhere else. My story 'Six: Welcome to the Caribbean' is the first in four that has this explanation in it. I'm very sorry for any confusion this may cause, but I'm still working to get 'Six' written outside of Wattpad as well as on Wattpad. Characters from: Supernatural, BBC Merlin, ABC Once Upon A Time
