"Comatose" doesn't work that way...oh never mind.
The person in charge of 13th is, as Natsuko mentioned in her discussion, the 3rd seat. It just so happens that character has no player at the moment, so technically 13th is under the "control" of horngeek (the player) at the moment, since the Captain controls all unplayed/unclaimed members of their division. Am I wrong?
