MadMonkey: I was thinking the opposet - that is they set a lot of vacations when they were a members, so they could be used now that they have less vacation days - taking advantage of a loophole of when you become a pawn.
Of course that is just my opinion. Has anyone talk to the person to see if they are going to be back or not? Otherwise, like someone else said - Fencer would be able to move control to someone else... and if sometime Kili does come back, it can always be given back to them at that point.
