"I didn't figure that," someone says, and the room goes quiet for exactly the right reason. The episode hands you a puzzle, takes away two pieces, and smiles politely while you look under the sofa. The episode leans on reruns of earlier moments, which is nostalgic the first time and less so the fourth. There is a new face, Georgia, who walks in like they already know how this ends. The sort of episode that makes the credits feel rude.
