I suppose it says something about where we're at with incest that I barely blinked when 'Game of Thrones' introduced us to Queen Cersei and her brother Jamie Lannister, only to show them in flagrante during the first 50 minutes of the show's premiere. If confronted with this sort of behavior from real people, I'm pretty sure I'd say more than, "But isn't that her twin brother? Ohhhhhh." But when it comes to fictional people, lately it seems like a little inter-genetic action is par for the course.
