The elevator getting fixed, that's an easy one. Penny being pregnant, not a big surprise. Buffy the Vampire Slayer cameo was ridiculous. Howard and Bernadette's kids were already too big for cribs. The only things I was waiting for all season were about Howard. For most of the entire 12 seasons they made fun of him never becoming a doctor. He even mentioned he wanted to finally become one years ago. Could they at least of reunited him with his long lost father? That was one of the biggest plots in the entire series left unanswered. He already met his half brother, so obviously there's a twist to it.
