Sheesh, where to start? We're big fans of 'How I Met Your Mother,' so naturally we're keen to see if series creators Carter Bays and Craig Thomas actually introduce the mother, or throw us a curveball to explain the ninth season. We're not sure about 'The Big Bang Theory' once again throwing a wrench into the relationship between Leonard and Penny, but how about the 'Elementary' finale? Looks like CBS isn't too shy about bumping up 'Game of Thrones' star Natalie Dormer to a bigger role! And might we meet Moriarty?

Well, what say you? Are you shocked by any of the CBS finale spoilers? Which closers are you most looking forward to seeing?
