Mr. X is currently an imaginary figure holding a place slot, as a NB exchange with one of our other normal players leads me to believe I'll be able to put them in that role inside a couple weeks, and it can also be used as a sub if someone else shows up or barring that if a few players get whacked. Mr. X can be lynched normally or NK'd or copped or whatever just like anyone else, and he/she has already be assigned a role just like everyone else, but he is inactive for voting purposes until claimed. At the time of this writing I myself have no idea what role Mr. X will have, so he could be anything form plain vanilla to cop to scum godfather or serial killer.
