They say that all good things must come to an end, and that is now sadly the case for The CW's Supernatural.
With 14 seasons already in the books, the adventures of Dean and Sam Winchester will conclude with a fifteenth and final season that commences this October. Where things go after Season 15, who knows. Considering that the brothers Winchester have already been featured in novels, comics, anime and even alongside Scooby-Doo, it seems likely that the show coming to an end may not really mean the end for these beloved characters.
By any stretch of the imagination, 15 full seasons is a ludicrous amount of time for a TV series to run for - so much so, Supernatural has long since established itself as the longest-running live-action fantasy TV show in the history of American television.
Throughout the 14 seasons to date, audiences have seen Dean and Sam battle all kinds of monstrous beasts and nefarious threats, as friends have become enemies, enemies have become friends, and all manner of plot twists have played out.
How well do you remember those 14 seasons to date, though? Here, there's a quiz that even the most ardent of Supernatural fans will struggle to get 100% on!
