It is a heavy episode, the kind that sits on your chest like a well-meaning cat. The smartest person in the room has a very public breakdown, and it is about as dignified as a cat in a bathtub. The episode leans on reruns of earlier moments, which is nostalgic the first time and less so the fourth. Listen for "Yeah, I was just...", a line that does more work than most of the supporting cast. Watch it only for completeness, and maybe at double speed.
