Summary of “This Season’s Most Shocking TV Plot Twists”

You need to see it.” And even in our live show, when Chris is giving almost the emotional equivalent of a parental-discretion-advised warning: “This is not going to be an ordinary night. It’s going to be incredibly emotional, it is going to be tough, there’s going to be a lot of feelings, we’re all going to have a lot of opinions.” So you see that, and you can just feel TVs turning on, like, Oh my God, something big is going to happen here.
