Somewhere along the way, a brilliant schemer discovers yelling as a strategy; reviews are mixed. It is a heavy episode, the kind that sits on your chest like a well-meaning cat. Listen for "Master. Soon you will want to...", a line that does more work than most of the supporting cast. The episode leans on reruns of earlier moments, which is nostalgic the first time and less so the fourth. Good enough that your phone stays in your pocket. Mostly.
