6. Syrio Forel
Arya's 'dancing master' was another character that I quickly became fond of and was sad to see go. He was likeable, inspiring and definitely one of the more interesting characters that Arya meets throughout the series. He also proved to be a hell of a swordsman, quickly and effectively dispatching Lannister guards with a wooden sword. Syrio was an awesome character who I definitely miss now he's not in the show however his place on my list of deaths is a bit of a grey area for me. Other GoT conspiracy theorists and I have noticed that following his awesome display of wooden swordsmanship against the Lannister guards, there follows a scene with a disembodied scream. Naturally this hints that Syrio might have finally met his match, but what if he didn't? What if he's still alive and waiting to make an amazing reappearance? Possibly a far-out theory but assuming he's dead for the purposes of this piece he definitely deserves a place on this list for being a fantastic character who I definitely wish I'd seen more of.
