This week, when an influential Cardassian figure dies, a whole host of potential heirs line up to fill his boots. But when a derelict starship starts asking questions about the afterlife, Sisko has to stay on his toes to make sure he isn’t the one who gets Sunday-schooled. Will Dukat get that big promotion? Will O’Brien get to play with a new toy? And can DS9 get its outbreak of crabs under control? All this and more in Valhalla, where we take on the ugly elephant in the room.
