I love this episode because of the scene where TC wins the final bingo round. He's so excited and suddenly just lunges at Higgins and hugs him, knocks over the stand with the ball-roller.
My daughter and I love this, because we have the strong impression that Hillerman was on the verge of breaking up with laughter....look at him, after TC lets go. It's a real smile, and he just has that "about to explode" look to him.
We have a private theory that Hillerman walked offscreen right then because he had to, before he lost it--that was such a great bit of exuberance on Roger Mosley's part, he wouldn't want to ruin the take.
Also, someone posted that Hillerman looked good in the light-colored suit, and that he hadn't worn it in other episodes? Or something to that effect. He wore a light suit later, at the end of Letter to a Duchess...I'm still working through this season, so I can't speak to other times.
