If it had been a...I don't want to say normal, but a not so blatantly freakish and depressing pregnancy, their reactions would have made so much more sense. The fact that it wasn't, and had been made clear multiple times that it wasn't through Carol's emotional state and, y'know, the fact that she went into labor after three days of being pregnant, made the entire thing horrifying. It was like there was two entirely different stories being told here, with a horrible attempt to squish them into one.
