Well, Percival obviously isn't in that picture (it would be hard not to spot that tall knight amongst others), so it could mean that the seat is his. Perhaps something happened to him and that is the reason why he is missing? Maybe that'll even mean that there will be an episode that focuses more on him? That would be AWESOME, especially since he is my favorite knight. :)
