Another One?

It’s happened again. I’ve lost another follower, and I can’t work out who it is. I’ve been expecting to lose one all week, because when your anticipated Third Queen proves to be illusory you can expect the sky to fall in at the very least. (Not that you’d be in any mood to notice an event of such little consequence, of course, since losing a Third Queen is a matter of rather more magnitude.) Anyway, it isn’t her. So I wonder who it is.
