Yes, from the moment that they mentioned that a person couldn't have a B-12 shot if they were pregnant, I knew, I just knew, that someone was going to announce that they were pregnant. Who would it be was the only question remaining. Would it be Harriet? Pregnant by her famous athlete boyfriend? Or would it be Jordan, pregnant by her scuzzy ex-husband? And when they kept using the pregnant joke in the episode... well, that just made it more obvious to me that someone was with child.
So while that part wasn't a surprise, the episode still holds up as another great episode of Studio 60. They keep throwing twists, and making the characters more complex and interesting as the series continues. I hope that the series stays around for a long time, so that we can really get to know the people in this tv-world.
